bare copper wire

Bare copper conductors are a range of uninsulated, unsheathed, multi-strand copper wire. Compared to solid conductors, the stranded structure improves flexibility and processability, making it suitable for a variety of electrical systems requiring uninsulated bare copper conductors.

NM-B cable

bare copper cable

Bare copper conductors employ a multi-strand stranded structure, which allows the conductor to maintain good mechanical flexibility and deformation adaptability even without insulation.

Advantages of bare cu wire

Bare copper conductors combine high conductivity with excellent flexibility, making them easier to install, bend, and process compared to solid copper wire. Furthermore, different stranding grades (soft annealed, medium-hard, hard drawn) can be selected to optimise strength or flexibility depending on the application requirements. As a bare copper material, it exhibits stable performance in grounding systems, overhead lines, distribution networks, and equipment connections, and because it lacks an insulation layer, it can be directly contacted or soldered to components.

APPLICATIONS

Bare copper conductors are primarily used in electrical and grounding systems requiring bare copper contact, such as power grounding down conductors, bare conductors for transmission lines, busbar connections, overhead conductor assemblies, and internal grounding circuits for equipment. They are commonly used in substations, distribution cabinets, and industrial installations to manufacture jumpers, grounding grids, and other applications requiring high conductivity and machinability.

NM-B Cable for Lightning Protection

Lightning Protection System

In lightning protection systems, bare copper cable is often used as a lightning rod down conductor and lightning protection grounding conductor. Its main function is to quickly and safely conduct the instantaneous large current generated by lightning strikes to the ground. Bare copper conductors can effectively reduce the risk of overvoltage and heat accumulation during lightning strikes.

THHN Cable for Industrial Plants

Electrical Grounding System

Bare copper cable is widely used in various electrical grounding systems and is the most basic and critical safety conductor in buildings, power facilities, and industrial installations. It is typically used to connect grounding electrodes, grounding grids, and equipment grounding terminals, providing a low-impedance, reliable discharge path for current in the event of leakage or fault current.

 

Bare Copper Cables for Equipment Grounding Conductor

Equipment Grounding Conductor

Bare copper cable is commonly used as an equipment protective grounding conductor to reliably connect the metal casings, cabinets, distribution boxes, and control cabinets of electrical equipment to the grounding system. When insulation breakdown or internal faults occur in the equipment, the bare copper grounding conductor can quickly conduct the fault current, triggering the protective device to operate.

 

Bare Copper Cable for Railway

Railway

In railway and rail transit systems, bare copper cable is widely used for signal system grounding, equipment grounding, and track return systems. Bare copper wire provides stable electrical connections, ensuring reliable signal system operation while effectively reducing electromagnetic interference. For long-term, high-reliability applications in railway and urban rail transit infrastructure.

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:

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.

Our factory provides return and exchange services. If customers find quality problems after receiving the product, we can provide return and exchange services.
Q

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.
