TW wire
TW wire is a type of thermoplastic insulated wire certified to UL standards, commonly used in general power, lighting, and building wiring applications. TW is part of the UL 83 standard and is often found alongside THW as a common type of single-conductor wire.
TW wire
TW wire uses solid or stranded annealed copper conductors and PVC insulation, and can operate safely in wet/dry environments from -10 °C to 60 °C.

APPLICATIONS
TW wire is widely used in residential, commercial, and industrial power distribution, including power lines, grounding, and lighting circuits. It can also be safely used in damp pipes, distribution boxes, and general building wiring scenarios, making it suitable for a variety of low-voltage applications.
Industrial Plant
In industrial plants, TW wires can be used for control circuits, auxiliary power supplies, and equipment power, especially in areas where high temperatures are not required, such as general power outlets, lighting circuits, or inside control cabinets. Their PVC insulation maintains stable performance even under humid conditions, making them suitable for most industrial power distribution scenarios.
Commercial Building
In commercial buildings, TW wire is used for lighting circuits, power branches, and power supply for air conditioning and equipment sockets. Installed in conduits, cable trays, ceilings, and distribution boxes, it provides reliable low-voltage power to various commercial electrical loads. TW's water resistance meets the specifications for damp areas in commercial spaces.
Residential Building
TW wires are commonly used in residential wiring for branch circuits, lighting circuits, and socket power supply, and are suitable for installation in conduits, cable trays, or walls. They can be used in both damp and dry spaces, such as kitchens, basements, or garages for lighting and socket circuits. Their moisture-resistant PVC insulation is ideal for these basic building wiring applications.
Pipes and Cable Trays
TW electrical wires are suitable for running through metal conduits, cable trays, and other passageways within buildings for power distribution across rooms or floors. Due to their flexibility and moisture resistance, they are easy to install within conduits and meet NEC/UL standards.

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.
