APPLICATIONS
RWU90 is primarily used in medium- and low-voltage power distribution systems in residential, commercial, and industrial buildings. It can be used as a service entry line, feeder, and branch circuit conductor, and is suitable for installation in cable ducts, trunking, and distribution cabinets. This cable supports both outdoor and direct underground installation and is commonly used in underground power distribution lines, outdoor distribution boxes, and power supply for public facilities.
Industrial Plant
RWU90 is suitable for factory buildings, power control rooms, and equipment power distribution systems, and can be used for power connections of equipment such as motors, pumps, fans, and compressors. Due to its oil, chemical, and moisture resistance, RWU90 is particularly suitable for installation in industrial environments with oil, moisture, or chemical media, such as manufacturing workshops, storage facilities, and public infrastructure power distribution systems.
Commercial Building
In building power distribution, RWU90 is often used as a service entry line to connect the power grid to the building's main distribution cabinet. It can also be used as a feeder and branch circuit conductor to supply power to lighting systems, socket circuits, air conditioning systems, elevators, and power equipment. It is suitable for wiring in cable ducts, cable trays, and distribution cabinets.
Outdoor and Underground
In both outdoor and underground applications, the RWU90 is capable of direct burial and is commonly used for underground power distribution lines, outdoor equipment power supply, power trenches, and outdoor distribution box connections. Its resistance to sunlight and weathering allows it to be exposed to outdoor environments for extended periods without affecting its electrical performance, making it suitable for power distribution in industrial parks, street lighting, and public facilities.
New Energy
In new energy applications, the RWU90 is also widely used in photovoltaic power generation systems for power connections between inverters, combiner boxes, and power distribution equipment. Furthermore, this cable is suitable for humid environments, low-temperature regions, and areas with significant temperature variations, maintaining safe and stable power transmission under various complex operating conditions.

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.
