GERITEL
Apr 14,2026
In 2025, a well-known spice processing enterprise in Zanzibar, Tanzania, launched a large-scale factory expansion project to meet the growing global demand for high-quality spices. As a key part of the project, the electrical wiring system directly determines the safety, efficiency and long-term stability of the factory’s production. After comparing multiple suppliers, the client finally chose Dongguan GERITEL Electrical Co., Ltd. (Greater Wire & Cable Co., Ltd.) as their exclusive wire supplier, relying on our professional solutions, high-quality products with international certifications, preferential prices and thoughtful sample services. This case study details how we helped the client solve core pain points and successfully complete the wire supply for the spice factory expansion project.
1. The Urgent Demand of a Spice Factory Expansion
Zanzibar, known as the “Spice Island” of Tanzania, is one of the world’s major spice production and processing bases. The client, a local leading spice processing company, has been engaged in the processing and export of cloves, cinnamon, nutmeg and other spices for more than 10 years. With the continuous expansion of its overseas market, the company decided to carry out a factory expansion project in early 2025, including the construction of new processing workshops, storage warehouses and supporting power facilities. The total area of the expanded factory is 8,000 square meters, and the daily processing capacity of spices is expected to increase by 50%.
However, the client encountered several key pain points in the selection of electrical wires for the expansion project, which directly affected the progress of the entire project: First, the local climate in Zanzibar is hot and humid, with frequent rainfall and high air corrosion, which requires the wires to have excellent moisture resistance, corrosion resistance and UV resistance; second, the spice processing workshop involves high-temperature drying, mechanical operation and other links, and the wires need to withstand high temperature, strong mechanical pressure and avoid fire risks caused by wire aging; third, the client has strict requirements on the project cost, hoping to obtain high-quality wires at a preferential price to control the overall investment of the expansion project; fourth, the project schedule is tight, and the client needs the supplier to deliver the goods quickly to ensure that the electrical installation can be carried out on time, so as to put the new workshop into use as soon as possible; fifth, as an export-oriented enterprise, the client requires all imported products to have international authoritative certifications to ensure compliance with Tanzania’s local electrical standards (TBS) and avoid customs clearance difficulties.
Before cooperating with us, the client had contacted two local suppliers in Tanzania, but their products could not meet the above requirements: the wires of local suppliers lacked international certifications, the quality was unstable, and there was a risk of insulation aging and short circuit in harsh environments; the price of imported wires from European suppliers was too high, which exceeded the client’s budget. At this critical moment, the client found our company through Google search and hoped that we could provide a comprehensive solution to solve their urgent needs.
2. Tailored Wires for Spice Factory Scenarios
After receiving the client’s inquiry, our professional team first conducted in-depth communication with the client to fully understand the specific needs of the spice factory expansion project, including the layout of the workshop, the power demand of processing equipment, the installation environment and the project schedule. Combined with the characteristics of the spice processing industry and the local climate in Zanzibar, we customized a set of wire supply solutions, focusing on three core wire models: H07ZZ-F, NYM-J and SWA, and matched corresponding specifications according to different use scenarios to ensure that each wire can play its maximum role.
First of all, for the internal wiring of the processing workshop and office area, we recommended NYM-J wires, which are specially designed for building internal wiring and have excellent insulation performance and mechanical strength. According to the client’s power demand, we provided multiple specifications, including the key specification 3×2.5mm NYM-J, as well as 2×1.5mm NYM-J, 4×4mm NYM-J and 5×6mm NYM-J. Compared with ordinary PVC wires, NYM-J wires adopt high-quality PVC insulation and sheath, which have better moisture resistance and corrosion resistance, and can adapt to the hot and humid environment of Zanzibar. At the same time, the multi-core design of NYM-J wires is more convenient for installation and layout, which can effectively reduce the difficulty of electrical construction and improve the construction efficiency. The client chose NYM-J wires mainly because they are more cost-effective than other building wires, and their performance can fully meet the internal wiring needs of the factory, avoiding the problem of frequent maintenance caused by wire damage.
Secondly, for the temporary power supply of the construction site and the connection of portable electrical equipment (such as mobile drying machines and conveyors), we recommended H07ZZ-F wires. H07ZZ-F is a flexible cable with crosslinked rubber insulation and outer sheath, which has the characteristics of fire non-propagation, low smoke and low corrosive gas emission, complying with IEC 60332-3 standards. We provided H07ZZ-F wires of 1×2.5mm, 1×4mm, 2×2.5mm and 3×4mm specifications. Compared with ordinary flexible wires, H07ZZ-F wires have better high-temperature resistance (operating temperature range of -15℃ to +90℃) and mechanical flexibility, which can adapt to the complex construction environment of the expansion project and avoid wire breakage caused by frequent movement. In addition, the low smoke and halogen-free performance of H07ZZ-F wires can effectively reduce the risk of toxic gas emission in case of fire, ensuring the safety of construction personnel and factory property.

Finally, for the external power supply lines of the factory, including the power connection between the main power distribution room and the workshop, and the outdoor power supply lines of the warehouse, we recommended SWA (Steel Wire Armoured) cables. SWA cables are manufactured in accordance with BS 5467 standards, with galvanized steel wire armour, which can provide maximum mechanical protection, effectively preventing damage caused by spade strikes, vehicle crossings and heavy-duty impacts. We provided SWA cables of multiple specifications, including 4×16mm, 4×25mm, 4×50mm and 4×120mm, to meet the different power transmission needs of the factory. Compared with non-armoured cables, SWA cables have stronger anti-interference ability and durability, and can be directly buried or embedded in concrete, which is suitable for outdoor harsh environments. The client chose SWA cables because they can effectively avoid the damage of external factors to the wires, ensuring the stable operation of the factory’s power supply system.
In addition to providing targeted wire models and specifications, we also launched a free sample service for the client. We sent samples of H07ZZ-F, 3×2.5mm NYM-J and SWA cables to the client’s factory, so that the client could conduct on-site tests on the quality, flexibility and insulation performance of the wires. At the same time, we provided preferential bulk purchase prices according to the client’s order quantity (a total of 8,500 meters of various wires were purchased), which helped the client save 15% of the wire purchase cost compared with European suppliers. This combination of sample service and price advantage became an important reason for the client to choose us.
3. International Certifications and Strict Quality Control
For industrial projects such as spice factories, electrical safety is the top priority. The client attaches great importance to the safety performance of wires, especially since the factory involves high-temperature processing links, and the risk of electrical fire is relatively high. To solve the client’s concerns, we highlighted our product certification advantages and strict quality control system.
All wires provided for this project have obtained international authoritative certifications, including IEC (International Electrotechnical Commission) certification, SAA (Standards Australia) certification and PVOC (Pre-shipment Verification of Conformity) certification required by Tanzania. Among them, PVOC certification is a mandatory certification for imported products in Tanzania. Our products have passed the strict inspection of the Tanzania Bureau of Standards (TBS), ensuring that the client can smoothly complete customs clearance at the port of Dar es Salaam without being detained due to certification issues. This solves the client’s worry about customs clearance difficulties, which is also an important advantage that local suppliers in Tanzania cannot match.
In addition, our company has established a strict quality control system from raw material procurement to product delivery. We use high-quality copper conductors, which have excellent electrical conductivity and heat dissipation performance, ensuring the stable transmission of electrical energy and reducing energy loss. The insulation and sheath materials are imported from high-quality suppliers, which have passed environmental protection and safety tests, and are non-toxic, odorless and pollution-free, in line with the environmental protection requirements of the spice processing industry. Before delivery, each batch of wires will undergo strict tests, including insulation resistance test, voltage withstand test, high-temperature resistance test and mechanical strength test, to ensure that the product quality meets international standards and the client’s requirements. For the SWA cables, we also specially tested the corrosion resistance of the steel wire armour to ensure that it can adapt to the humid and corrosive environment of Zanzibar.
4. Fast Response and Efficient Logistics
The client’s expansion project has a tight schedule, and the electrical installation work needs to be completed within 20 days, so the delivery speed of wires is crucial. After confirming the order, we immediately started the production arrangement, giving priority to the production of wires for this project to ensure that the production task is completed in the shortest time. At the same time, we cooperated with professional international logistics companies with rich experience in Tanzania routes to formulate an efficient logistics plan.
Considering the problems of slow customs clearance and high detention risk at the port of Dar es Salaam, our logistics team carefully sorted out the relevant documents, including PVOC certification, commercial invoice, packing list and other materials, and confirmed the accuracy of the documents with the client and the customs in advance to avoid customs clearance delays caused by incomplete or incorrect documents. In addition, we tracked the logistics status in real time and fed back the information to the client every day, so that the client could grasp the arrival time of the goods at any time.
With our efficient production and logistics arrangement, the entire batch of wires (8,500 meters in total) was delivered to the client’s factory in only 18 days, which was 7 days earlier than the client’s expected delivery time. This fast delivery speed ensured that the electrical installation work of the expansion project was carried out on time, laying a solid foundation for the factory to be put into use in advance.
5. Win-Win Cooperation and Client Recognition
With the support of our high-quality wires and professional services, the electrical installation work of the client’s spice factory expansion project was completed smoothly, and the new workshop was put into use one week earlier than planned. After several months of operation, the wires we provided have shown excellent performance: the NYM-J wires in the workshop have good moisture resistance and no insulation aging phenomenon; the H07ZZ-F wires on the construction site are flexible and durable, and no wire breakage or short circuit has occurred; the SWA cables for external power supply have strong anti-interference ability, ensuring the stable operation of the factory’s power supply system, and the power failure rate is zero.
The client’s factory’s daily processing capacity of spices has increased from 10 tons to 15 tons, and the production efficiency has been significantly improved. At the same time, due to the excellent performance of the wires, the maintenance cost of the electrical system has been reduced by 20% compared with the original factory, which has brought considerable economic benefits to the client. In addition, the preferential price we provided has helped the client control the project cost, making the investment return cycle of the expansion project shortened by 3 months.
The client is very satisfied with our products and services. They believe that our wires not only meet the quality and safety requirements of the project, but also solve their pain points in cost, delivery and customs clearance. The client said that they will take our company as their long-term cooperative supplier and will give priority to choosing our products in the future factory renovation and expansion projects. They also recommended our company to other spice processing enterprises in Zanzibar, bringing us more potential customers.
