Bare Copper Conductor Description
Bare copper conductors are simply copper wires, which makes them efficient at carrying current while minimizing resistance, making them ideal for a variety of applications. Copper is also naturally corrosion-resistant, making it suitable for some outdoor applications.
Bare copper conductors can be solid (a single strand) or stranded (multiple strands twisted together). Stranded conductors offer greater flexibility than solid conductors, making them useful in applications where the wires need to bend or pass through tight spaces.
We offer both annealed stranded copper and hard-drawn stranded copper. Annealed stranded copper is more flexible than hard-drawn copper, which in turn is more flexible than solid, hard-drawn copper conductors.
Annealed stranded bare copper is manufactured by EN 13602 and EN 60228 and is commonly used in renewable energy (including solar farms) and battery storage projects. Hard-drawn stranded bare copper, on the other hand, is manufactured by BS7884 and is more commonly used in the railway industry.
Bare Copper Conductor Construction
- Conductor
- Annealed: Class 2 annealed stranded copper
- Hard Drawn: Circular non-compacted hard drawn conductor (Class 2)
- Material
- Hard Drawn: Cu
Bare Copper Conductor Applications
- Grounding Systems: Bare copper conductors are widely used for grounding electrical systems, providing a safe path for electricity to flow to the earth in case of a fault.
- Overhead Power Lines: They are often used in overhead power transmission and distribution lines.
- Electrical Panels: They can be found in electrical panels and inside some appliances.
- High-Voltage Applications: Due to their excellent conductivity, they are used in applications where high voltage needs to be transmitted efficiently.
- Various Industrial Purposes: Bare copper conductors are used in a wide range of industrial applications, including machinery, heavy appliances, and more.
