YJLHV22 8.7/15kV Aluminium Alloy Conductor XLPE Insulated Steel Tape Armoured PVC Sheathed Power Cable

Overview

The YJLHV22 8.7/15kV is a three-core aluminum alloy power cable with XLPE insulation, copper tape screening, steel tape armour and a PVC outer sheath. Designed for medium voltage power distribution, it combines three insulated cores within one armoured cable assembly. This construction is suited to fixed installations where the cable route requires mechanical protection alongside electrical insulation and screening. Each core contains a stranded aluminum alloy conductor surrounded by its insulation system. Cross-linked polyethylene, commonly known as XLPE, provides the main electrical insulation. The copper tape screen forms part of the metallic screening system around the insulated cores. Filling and wrapping materials support the assembled cores, while the steel tape armour adds protection against external mechanical forces. The black PVC outer sheath covers the underlying cable layers. Together, these elements form the layered structure shown in the product cutaway. Typical applications include medium voltage feeders for industrial facilities, commercial developments and power distribution infrastructure. Depending on the project design and site conditions, installation routes may include cable trenches, tunnels or buried sections. Route selection should account for mechanical loading, moisture exposure, soil conditions and the applicable installation requirements. The presence of steel tape armour should be considered alongside the demands of the route when specifying protection and cable handling arrangements. For cable selection, confirm the 8.7/15kV voltage rating and choose the conductor cross-section using the calculated load, installation method and operating environment. Current capacity, voltage drop and short-circuit duty all affect the final specification. Terminations and joints should be compatible with aluminum alloy conductors and the cable's insulation, screen and armour construction. Correct preparation and installation are essential to the completed cable system. When preparing an enquiry, specify YJLHV22, the 8.7/15kV rating, three-core construction, conductor cross-section and required length. Include the intended installation environment and any project standards, test documentation or fire performance requirements. These details help establish the required cable configuration and provide a clear basis for reviewing technical suitability before ordering.
