Description

The LXHIV cable range, supplied by Cleveland Cable Company, comprises unarmoured medium-voltage power cables primarily designed to meet Portuguese utility distribution grid designs. Manufactured in compliance with international standards IEC 60502-2 and IEC 60228, alongside European reference framework HD 620, these cables cover operational voltage ranges from 3.6/6kV up to 18/30kV. The construction features a Class 2 stranded aluminium conductor layered with semi-conductive screens, cross-linked polyethylene (XLPE) insulation, and a high-performance copper tape metallic screen, all enclosed by a robust, flame-retardant black PVC outer sheath.

Engineered for dependable use in power transmission and distribution across utility sub-stations and heavy industrial networks, these cables provide a lighter alternative to copper variants. They are ideal for applications where physical space allows for the larger overall diameter of aluminium cores. The integrated flame-retardant PVC outer sheath delivers reliable resistance to fire propagation in line with BS EN/IEC 60332-1-2 standards and performs effectively under continuous maximum conductor operating temperatures of +90°C and peak short-circuit levels up to +250°C.

For general installation, these unarmoured cables are suitable for direct burial in trenches within free-draining soils, as well as pulling through underground plastic ducts and conduits. They are also widely deployed above ground for fixed routing on open-air utility structures, external building walls, and industrial indoor or outdoor cable trays.
