EPR Power Cable, 15,000V (Shielded), 3 Conductor

Three-conductor 15kV cable places the phase conductors within one overall cable assembly, which can simplify routing and installation in applications designed for a multi-conductor configuration.

Whether three-conductor or single-conductor cable is appropriate depends on the electrical design, installation method, equipment configuration, ampacity requirements, pulling conditions, and applicable specifications. A three-conductor construction can reduce the number of separate cables that must be handled, but the complete system design should determine which configuration is used.

Copper tape shielding provides a conductive layer around the insulated conductors that helps control the electrical field and provides a defined path associated with the cable shielding system.

In medium-voltage systems, shielding is an important part of controlling electrical stress around the insulation. Copper tape is one method of providing that shield. The shield must be properly terminated, bonded, and grounded according to the system design and applicable installation requirements.

The grounding conductor provides an equipment-grounding path separate from the phase conductors and cable shields.

The required ground-wire size varies with conductor size and the electrical design. The product table therefore lists the corresponding grounding conductor for each available cable size. Grounding requirements should always be confirmed against the project specification and applicable electrical code rather than selected solely from the cable's phase-conductor size.

Cable ampacity changes because surrounding installation conditions affect how efficiently heat can leave the cable.

Cable installed in conduit exposed to air may dissipate heat differently from cable installed in an underground duct system. That is why the product table provides separate ampacity values for these installation conditions. Final allowable ampacity can also depend on ambient temperature, conductor loading, grouping, duct configuration, soil conditions, and other design factors.

Confirm the required load, ampacity, installation method, voltage class, insulation level, allowable voltage drop, termination requirements, and project specifications.

The available sizes on this page range across multiple AWG and kcmil conductors, with corresponding differences in cable diameter, weight, grounding conductor size, and ampacity. Choosing the correct size therefore requires more than matching the voltage rating. Engineers and buyers should evaluate the entire circuit and installation before selecting a specific cable size.
