Bare wires are the most basic category of wire and cable products. Some products of bare wires can be used as conductive wires and cables; another part of products is used as components in equipment such as motors, electrical appliances, and transformers. In addition, bare wires can be directly used to transmit electric energy and information in electric power, communication, transportation and other departments. Bare wires should have good electrical conductivity and physical and mechanical properties.

Bare wires have only conductors without insulation and sheath structure.

 

 

The bare copper wire has good electrical conductivity and physical and mechanical properties.

The only function of the bare wire is to guide the unconventional current into the earth in an abnormal state (or in an accident), but in the normal state, no current passes through the grounding wire, so ensure the safety of the grounding wire. Good grounding is an effective means to prevent electric shock accidents and overload accidents.

Safety regulations uniformly stipulate that all grounding wires must be bare wires, including lightning protection grounding, anti-static grounding, protective grounding, etc.

 

 

Bare single wire is a wire with bare surface and no insulation layer, which is mainly used in the manufacture of electric power, transportation, telecommunication engineering, motors and transformers.

 

 

 

The bare wire is made of soft material, with excellent electrical conductivity and strong heat transfer capability.

Conductivity: Copper is one of the best conductors of electricity, making bare copper wire an ideal choice for applications that require efficient electrical conductivity.

Corrosion Resistance: Copper has natural corrosion-resistant properties, which helps maintain the wire's conductivity and prevents degradation over time. However, it may develop a patina or oxide layer when exposed to certain environments.

 

 

Bare copper wire must meet GB/T 3953 "Electrical Round Copper Wire", GB/T 4909 "Test Method for Bare Wire", ASTM B1 "Standard for Hard Drawn Copper Wire", ASTM B3 "Standard for Soft Round or Annealed Copper Wire", JIS C 3102 "Annealed copper wire for electrical purposes"

 

 

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.
