Structure size and technical parameter

Q: What is the structural composition of the JKYJ cable? 

A: JKYJ cable is mainly composed of copper core, cross-linked polyethylene insulation layer and protective layer. Copper core is responsible for conducting electricity as a conductor, and its material has good electrical conductivity. The cross-linked polyethylene insulating layer is wrapped in copper core, which can effectively isolate current and prevent leakage, and has excellent electrical properties and weather resistance. The protective layer protects the internal structure of the cable. 

Q: What are the advantages of JKYJ cable? 

A: It has many advantages. In terms of electrical performance, it can transmit power stably and reduce power loss. In terms of safety performance, due to good insulation performance, the risk of electric shock can be reduced. Moreover, this cable has a long service life, adaption to a variety of environments, whether in high or low temperature environments, can maintain better performance, reduce the frequency of maintenance and replacement. 

Q: What scenarios are JKYJ cables mainly used in? 

A: It is often used for overhead lines in urban power grids, such as power transmission in city streets. It is also suitable for the residential power supply line to provide safe and stable power supply for residents.
