Product details
Our bare copper conductors are principally used in energy transmission installations to maximise thermal and electrical conductivity, and to transmit energy with optimal efficiency. This uninsulated wire can be used as an earthing cable. The copper also offers natural resistance against environmental stresses such as wet, humid, and saline climates.
1. Highly conductive soft or hard drawn stranded copper cable
2. Tinned soft drawn stranded copper cable available on request
3. Bare stranded copper cable supplied unbranded
Solid and stranded (classes AA and A) bare copper are suitable for overhead transmission and distribution applications. Stranded conductor of greater flexibility (classes B and C) are suitable for uninsulated hook up, jumpers, and grounds in electrical construction. Soft Drawn copper is unilay construction.
Our technical engineers have vast experience of providing support with the selection of the optimum bare copper conductor. We also offer innovative logistics solutions to help improve supply chain efficiency. Please call us to discuss your specific requirements.
KINGYEAR from 2013-2018 are mainly for domestic trading and processing to some export trading companies. The average sales amount are about RMB 320,000,000 per year. For cables oversea market, From last may till now we have expanded our market to Bolivia, Peru, Dominican, Philippines, Vietnam, Thailand, Iraq, Mongolia, Indonesia and some Africa country. With total sales amount over USD10,000,000.
