Advantages of RHW-2 cable

Both RHW and RHW-2 cables feature annealed bare copper or tinned copper conductors conforming to ASTM B3/B8 standards, providing excellent conductivity and mechanical strength. Their insulation layers are made of thermosetting cross-linked materials (such as XLPE or equivalent thermosetting compounds), with a uniform and dense insulation layer that tightly encloses the conductor, providing reliable electrical isolation and environmental protection. The main structural difference between RHW and RHW-2 lies in the heat resistance rating of the insulation material, allowing them to meet different application requirements of 75°C and 90°C, respectively.

APPLICATIONS

Both RHW and RHW-2 cables are suitable for installation in conduits, raceways, cable trays, and other installation environments that meet NEC requirements, and can be used in indoor and outdoor damp areas. RHW is more suitable for conventional power distribution applications with temperature requirements of 75 °C, while RHW-2 is more suitable for high-load, high-ambient temperature, or projects requiring higher system margins.

RHW RHW-2 cable for Industrial Plant

Industrial Plant

In manufacturing plants, RHW/RHW-2 cables are used to provide power to large motors, production equipment, and control cabinets. They can withstand the temperature rise, oil contamination, and humidity conditions of industrial environments.

RHW RHW-2 for Commercial Building

Commercial Building

In commercial buildings such as office buildings, shopping malls, and hotels, RHW/RHW-2 cables are commonly used for feeder connections between the main power distribution panel and the distribution boxes on each floor.

RHW-2 Cable for Cable Tray

Cable Tray

RHW/RHW-2 Cable is commonly used for multi-circuit centralised installations in cable tray or cable management systems in commercial and industrial buildings. Its thermosetting insulation remains stable even under high-density conditions.

RHW-2 Cable for Renewable Energy

Renewable Energy

RHW/RHW-2 Cables are used in photovoltaic power plants, energy storage systems, and supporting power distribution lines for AC side or auxiliary power supply lines. Their performance is adaptable to outdoor and high-temperature operating conditions.

Customer Reviews of Geritel Wire

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.

UL Wire for Factory Construction

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.

UL Cables for Hotel Project

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.

What is your quality assurance process?

We will select and inspect the raw material and conduct strict quality inspections on each batch of raw materials. During the production process, the factory usually uses automated equipment and online detection systems for real-time monitoring. For example, the diameter of the copper wire, the thickness of the insulation material, and the twisting process during the wire drawing process all need to be precisely controlled. At the same time, we regularly take a certain number of wire and cable samples for inspection. These inspections include, but are not limited to, tests such as size, insulation resistance, conductivity, and mechanical strength. Each batch of wires and cables produced will be fully tested before leaving the factory. If quality problems are found in the product testing, the factory will take "traceback" measures to find the root cause of the problem and correct possible deviations in the production process. After production is completed, all wire and cable products will undergo a final quality inspection. In the packaging stage, the wires and cables will be properly packaged according to the specifications to ensure that they are not damaged during transportation. In addition, we have a professional after-sales team to respond to customer feedback and complaints promptly to ensure that problems encountered by users during use are solved promptly. In addition, the factory will regularly visit customers to collect product usage feedback and further improve product quality.
