BS7835 12.7/22kV LSZH

Our range of Nexans BS7835 12.7/22kV LSZH medium voltage cables is designed for power distribution across data centres, industrial facilities and utility infrastructure where low-smoke, halogen-free cable construction is specified. Featuring copper conductors, XLPE insulation, metallic screening and a Low Smoke Zero Halogen (LSZH) outer sheath, these cables are suitable for medium voltage networks requiring defined electrical performance and fire-related material characteristics. Available in single-core and three-core configurations, with Aluminium Wire Armour (AWA) or Steel Wire Armour (SWA) according to the cable design, they support a range of fixed electrical installations.

Why Choose Nexans BS7835 22kV LSZH Cable?

  • Rated at 12.7/22kV (24kV maximum system voltage) for medium voltage power distribution.
  • Manufactured to BS 7835 for applicable LSZH medium voltage cable requirements.
  • Copper conductors and XLPE insulation for electrical power transmission and distribution.
  • Metallic screening forms part of the cable construction for medium voltage applications.
  • LSZH sheath materials help reduce smoke emissions and corrosive halogen gas release during a fire.
  • Flame-retardant performance is assessed against the applicable cable test standards.
  • AWA single-core and SWA three-core options are available in relevant cable constructions.
  • Suitable for specified installations underground, in ducts or in air.

When specifying Nexans 22kV LSZH cable, consider conductor size, electrical loading, fault levels, installation conditions and the required mechanical protection. The selected cable must meet the project's electrical design and fire performance requirements, with the individual product datasheet used to confirm the precise construction and applicable standards.

In data centre developments, medium voltage cabling can form part of the incoming power supply and site distribution network feeding transformers and downstream electrical systems. Selecting the appropriate BS7835 construction helps align cable specification with the wider infrastructure design, particularly where low-smoke, halogen-free materials are required.
