250 mm² Copper THHN/THWN‑2 Wire –Extreme‑Duty Tray & Conduit Conductor
Engineered with a heavy‑duty PVC insulation and a rugged nylon jacket, this 250 mm² copper wire is rated 600V and UL 83 listed, built to handle the heaviest industrial loads in the Philippines. Despite its massive cross‑section, the stranded construction maintains manageable flexibility for field routing in trays, conduits, and underground ducts.

THHN/THWN-2 Cable
THHN/THWN‑2 cables bearing the Philippines Standard mark undergo strict quality assurance, ensuring consistent performance in tropical climates and corrosive coastal areas. Their dual‑rated insulation (dry/wet) reduces inventory needs and simplifies material selection for large projects.

Advantages of 250 mm² Copper THHN/THWN‑2 Wire
The 250 mm² size delivers near‑maximum ampacity, making it a staple for main switchboard feeders and large transformer connections. Its tough nylon jacket guards against mechanical damage during installation, while the stranded conductor bends easily for termination in cramped switchgear rooms.

What are people saying about us
Reliable factory quality, fast delivery and professional technical support for bulk wire orders.


Luis Fernando Pérez - Venezuela - Office Building Project
The wires are of very good quality. The cables need to pass through long pipes and corners, and the cables are very flexible. We also ordered fire-resistant wires, which have been tested by a testing agency and found to be without problems.


Thomas Baker - USA - Factory construction
GERITEL WIRE's engineering team was very professional. They offered suggestions based on our cable requirements, and we found more suitable cable models. Subsequent operation has been stable without any problems.


Ricardo José Herrera - Dominican - Hotel Project
Due to the tight schedule of the hotel project, we had to adjust the usage quantity several times. GERITEL WIRE supplier was very flexible in terms of delivery and packaging, with fast delivery times. The wire reels were clearly labeled, making on-site counting and distribution very convenient.
