Products Description
Bare copper wires, both internally and externally, are composed of copper metal. These wires, extracted from pure copper rods, come in various specifications. They lack any type of coating or insulation, such as varnishes or conductive materials, and retain their natural copper color. Physically, bare copper wires are pliable and possess excellent electrical conductivity.
The most fundamental type of wire and cable products on the market is bare CU wire. These versatile products can be used as conductive wires for electrical wiring and cabling, or as components in motors, electronics, electrical installation cables, and other equipment. With a wide range of applications, bare copper wire is an essential component in many industries. Whether you need a reliable conductor or a durable component for your electrical projects, bare copper wire is an excellent choice.
The processing of bare CU wires is carried out based on specific requirements and combined to form different types of wires such as stranded wires and multi-stranded wires, depending on the specific needs.
The wires and cables used in electrical systems can be classified into two types based on their function. The first type is the carrier electromagnetic wire, also known as the winding wire, which serves the purpose of converting electric energy into magnetic energy or vice versa. The second type is responsible for transmitting signals through the electrical system. Both of these types of wires play an important role in ensuring the proper functioning of an electrical system.
Wires and cables are extensively used in both major power and information systems. These systems begin at the initial point, like generators and signal transmitters, and progress through various nodes such as transformers and program-controlled switches. Finally, they reach user terminals that consist of household appliances, telephones, televisions, and computers. The interconnectivity of all these devices relies on the abundant use of wires and cables throughout the entire system.
Product Features
Bare CU wire possesses excellent electrical conductivity and exhibits remarkable physical and mechanical properties. Let me generate a highly similar content by rearranging the above information.
Application field
Cables derived from bare CU wires find extensive applications in the domains of cables, electromechanical systems, and electronics. The processing of these wires enables their transformation into various types of cables that are widely utilized in these industries.


Physical properties
The bare copper wire exhibits remarkable electrical conductivity and robust heat transfer ability, while being soft in nature.
QA&QCQuality Assurance and Quality Control
According to the guidelines set forth in GB/T 3953 "Electrical Round Copper Wire" and GB/T 4909 "Test Methods for Bare Wires", it is imperative to produce and thoroughly inspect bare CU wires. These wires must adhere strictly to the specified standards and undergo rigorous quality checks. By following these guidelines, the production process can ensure the delivery of high-quality bare CU wires that meet industry requirements. Through compliance with these regulations, the safety and reliability of bare CU wires can be guaranteed, providing peace of mind to end-users and contributing to overall electrical system efficiency.
Packaging, storage, handling and shipping
After the bare copper wire is produced, it must be packaged, stored, handled and transported in strict accordance with customer and industry standards to ensure that the product is free from moisture and damage.
