Type USEI/USEB is the most widely used cable for underground secondary distribution and service entrance applications at 600 volts or less. The aluminum alloy 1350 USEI75 phase conductors are insulated with black polyethylene (LLDPE). The USEI90 and USEB phase conductors are insulated with black crosslinked polyethylene (XLPE). Each USEI75 and USEI90 phase conductor has a colour-coded, flame retardant, sunlight resistant PVC jacket applied over the insulation prior to cabling. USEB conductors are cabled together and a copper concentric neutral is applied. The entire USEB assembly is then covered with an overall PVC jacket.
