Underground service entrance cable · 1/0 AWG 3 conductor aluminium XLPE/PVC 600 V direct burial · Prysmian 1/0/3USEI90

What this product is for

This USEI-90 cable is used for underground secondary power distribution at 600 V or less. It is built for direct burial or duct installation between utility secondary distribution points, meter bases, and similar low-voltage service entrance applications.

Use for

Use for underground service entrance runs, secondary distribution, and other buried or ducted low-voltage feeder applications where aluminium conductors and 90 deg C wet or dry rated insulation are acceptable. Typical applications include residential subdivision services and some light commercial underground distribution.

Avoid for

Avoid using this cable where an armoured cable, exposed building wire, or a cable type intended for interior open wiring is required. Do not substitute it for cable types with different construction or termination requirements.

Best for

Best for electricians and utility-related contractors needing a 3 conductor underground cable with compact aluminium conductors, XLPE insulation, PVC jacket, and CSA USEI-90 compliance for Canadian installations.

Installed in

Installed directly in earth or in underground duct systems. Portions of the cable may be exposed to sunlight at termination points or during storage where permitted by the product construction and code requirements.

Why this product exists

USEI-90 cable provides an underground service entrance construction that combines compact aluminium conductors with RW90 XLPE insulation and a weather-resistant PVC jacket. This helps reduce installation cost versus copper in many underground secondary applications while maintaining a 600 V rating and 90 deg C conductor rating in wet or dry locations.

Compared with similar products

Compared with single-conductor RW90 aluminium in conduit, this cable provides a factory-assembled underground service entrance construction for direct burial or duct use. Compared with armoured cable, it is intended for underground secondary distribution rather than exposed mechanical protection applications.

Typical buying guidance: 1/0 AWG aluminium underground cable is commonly selected where a larger secondary feeder is needed, but final conductor sizing, voltage drop, and overcurrent protection must be confirmed from the Canadian Electrical Code, run length, and utility or project requirements. Actual performance depends on installation conditions, layout, and local electrical code.
