USEI-90 Underground Cable

Application & construction

USEI-90 underground distribution cable is designed to be used for secondary distribution and underground service operating at 600 volts or less. Cables are intended for underground installation, either direct burial or in duct systems.

Structure

1. Conductors — Compact stranded aluminum conductors class B or compact stranded copper conductors class B
2. Insulation — Cross-linked polyethylene (XLPE) insulation meeting the requirements of CSA C22.2 No. 38 for Type RW90 insulation
3. Jacket — PVC outer jacket, weather resistant, sunlight resistant, cut-through resistant, FT1 rated material
4. Neutral conductor — The neutral conductor may be the same size as the power conductor, or it may be reduced
5. Phase identification — by jacket color coding, with sequential printing — three conductor cable: red and black power conductors and a white neutral; four conductor cable: red, black and blue phase conductors and a white neutral
