How to improve the thermal stability of OPGW cable?
by admin on 21-08-31
Today, GL talks about how to improve the common measures of OPGW cable thermal stability: 1. Shunt line method The price of OPGW cable is very high, and it is not economical to simply increase the cross-section to bear the short-circuit current. It is commonly used to set up a lightning protectio...
