Overview
YJV 8.7/15 kV XLPE power cable is designed for fixed medium voltage power distribution in industrial plants, substations and commercial infrastructure. Combining copper conductors, cross-linked polyethylene insulation and a PVC outer sheath, it provides a practical cable option for projects requiring an unarmoured construction. The rated voltage designation, U₀/U, is 8.7/15 kV. The copper conductor carries electrical current, while XLPE insulation provides the main dielectric layer. Medium voltage cable construction also incorporates conductor and insulation screens, together with a metallic screen. The PVC outer sheath covers and protects the underlying cable components. The detailed screen design, conductor construction and cable dimensions should be defined in the approved technical specification, allowing buyers to compare offers on a consistent basis. Typical applications include distribution feeders within industrial facilities, connections between substations and distribution equipment, and other permanent medium voltage circuits. YJV cable can be considered for cable ducts, tunnels and appropriately protected cable routes. Selection depends on the installation environment, mechanical protection and the electrical requirements of the network. For engineering and procurement teams, cable selection starts with the core configuration and conductor cross-section. Current-carrying capacity, voltage drop and short-circuit requirements must be assessed against the actual installation conditions. Ambient temperature, cable grouping and installation method all influence the final selection. Cable dimensions and screen requirements also help determine compatibility with joints and terminations. For a comparable quotation, provide your cable schedule, required lengths, total quantity, installation method and destination. Include the applicable manufacturing standard, screen specification, sheath requirements and any project inspection requirements. Agree on the technical datasheet, compliance documentation and required test reports before placing the order. Specifying drum lengths, cable marking and packing requirements at the enquiry stage also helps align delivery with site installation plans. Whether sourcing for a new distribution project or replacing an existing feeder, a clearly specified YJV 8.7/15 kV cable makes technical evaluation and purchasing more straightforward. Send your project requirements to request a quotation aligned with your approved cable specification.
