What are Overhead Cables?

2023-05-23 275

Overhead harness cables are overhead power lines that use multiple insulated phase conductors tightly bundled together, usually with an exposed neutral conductor. This contrasts with the traditional practice of using uninsulated conductors separated by air gaps. This variant of overhead power lines uses the same principles as bundled conductors, except they are closer to the point of contact, but each conductor is surrounded by insulation.


The use of overhead cables can greatly reduce various short-circuit faults. Compared with overhead bare conductors, the failure rate is 4-6 times lower.
