APPLICATIONS
TW75 wire is widely used in electrical wiring systems for residential, commercial and industrial buildings, such as lighting circuits, socket circuits and power branch lines; it is also commonly used for wiring inside distribution boxes, control cabinets and switchgear, as well as in industrial and electrical installation environments with high humidity but no direct water contact.
Industrial Plant
Inside industrial Plant, the TW75 wire is used for power and control wiring connections. Its multi-strand copper conductors provide adequate flexibility to accommodate minor vibrations generated during equipment operation, making it suitable for fixed or limited-movement internal wiring applications.
Commercial buildings
TW75 is used in electrical wiring systems of commercial and office buildings for lighting circuits, socket circuits, and power branch lines. It meets the basic safety and stability requirements of building electrical systems and can be laid in dry or humid environments.
Electrical control system
The TW75 wire is suitable for internal wiring in electrical control systems, used for power circuit and control circuit connections, meeting the stability and ease of installation requirements of control systems, and is suitable for industrial environments with high humidity and no direct water contact.
Indoor
TW75 wire is moisture-resistant and can be used in indoor environments with high humidity, such as basements, equipment rooms, and computer rooms. As long as there is no direct contact with water, TW75 maintains good insulation performance and reliability.

What are people saying about us
Our customers have consistently shared positive feedback about our cables and services. Here’s what they say about US:
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.
