APPLICATIONS
TWU wire is widely used in underground power supply lines, power connections between buildings, outdoor lighting and equipment power supply, underground branch lines of electrical systems, and industrial and building electrical wiring in humid environments. It is a commonly used type of wire for outdoor and underground power transmission.
Industrial plant
In industrial plants, TWU wire is commonly used in underground power distribution lines and outdoor electrical systems. Its environmental resistance allows it to adapt to complex operating conditions, ensuring the safe transmission of power and control signals in both outdoor and underground environments.
Outdoor electrical
In outdoor electrical systems, TWU wire is commonly used for power supply and control lines below or near the ground, such as yard lighting, electric gate systems, outdoor monitoring equipment, and auxiliary electrical devices. Its insulation material can withstand the effects of soil moisture, rainwater infiltration, and environmental changes.
Humid environment
TWU wire is suitable for high-humidity locations such as basements, under equipment foundations, cable trenches, and near drainage areas. TWU wire possesses stable insulation properties and moisture resistance, enabling reliable operation even under prolonged humid conditions.
Underground power supply
TWU wire is mainly used for underground power supply lines between buildings and between main power distribution systems and branch equipment. Due to its good moisture resistance and mechanical strength, it can be directly buried underground under conditions that comply with electrical codes, and is used to provide stable power to outdoor lighting fixtures, equipment rooms, pumping stations and other facilities.

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.
