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.

15kV/25kV/35kV Multi-layer Tree Wire

Used for primary and secondary overhead distribution where limited space is available or desirable for rights of way. Installed as an uninsulated conductor; however, covering is effective in preventing direct shorts and instantaneous flashovers should tree limbs or other objects contact conductors in such close proximity. The resulting close-proximity configuration minimizes the amount of space […]
