Secondary URD Cable
Secondary UD underground distribution cables are used to run power from a pad mounted transformer to the service entry or meter of a structure. The cables are rated for installation in underground duct or directly buried in earth. They are offered in single conductor, duplex, triplex, and quadruplex.
