Structure Size and technical parameter

Q: What kind of cable is the JKY/JKLY cable? 

A: JKY/JKLY cable cable is copper core (aluminum core) polyethylene insulated overhead cable. 

Q: What are the characteristics of JKY/JKLY? 

A: Its copper core (aluminum core) has good electrical conductivity and can efficiently transmit current. The polyethylene insulation layer has good insulation performance and can effectively prevent the occurrence of leakage. JKY cable structure is relatively simple, light weight, easy to install and erect, suitable for use in overhead lines. At the same time, it has a certain ability to adapt to the environment, and can work stably under normal climate and environmental conditions. 

Q: What scenarios are JKY cables mainly used in? 

A: JKY cable is mainly used in overhead power transmission scenarios, such as in rural power grid construction, because of its relatively low cost and can meet the basic power transmission needs, it is widely used in power transmission lines from substations to villages. It is also often used in small industrial parks or power distribution lines around towns.
