ZMS Cable is a leading supplier of medium voltage cables in China, which we consider to range between 3.6kV and 35kV. For higher voltages, please visit our high voltage cable specifications to find the right cable for your application.  

Our MV XLPE insulated cables are manufactured in accordance with various British and international Standards. These include armoured cable to British Standard BS6622 and BS7835; international Standards including IEC 60502-1 and IEC 60502-2; as well as a wide range of international construction specifications, including N2SXY, N2XS2Y, N2XSEY, NA2XSY and NA2XS2Y.

Custom designed medium voltage cable

Copper or Aluminum conductor with cross-sectional area: generally 35mm2 up to 100mm2

Number of cores: generally one or three

Solid or stranded aluminium conductors: for applications requiring a lighter cable weight, also often more economical due to lower aluminium prices. 

Stranded copper conductors: for applications requiring a smaller overall diameter and higher transmitting properties.

Bedding

Bonded or strippable out semi-conducting layer

Water tightness: longitudinal, longitudinal + quasi-radial, longitudinal + radial

Insulation layers (conductor screen, insulation and insulation screen): XLPE, which is more commonly used for MV cables, or EPR which is more flexible and often better suited to marine and offshore applications.

Metallic screen: to nullify the electric field outside the MV cable. Concentric copper wire screens, Aluminium foil laminate, or extruded lead alloy sheath.

Twisted three-core cable or triplex 

Armouring: for mechanical protection. Aluminium wire armoured for single-core cables, Galvanised steel wire armour, strip or tape.

Tapes: Separator tapes to facilitate peeling, water-swellable tapes to prevent water ingress, Conductive tape for core binding.

Outer Sheath: compounds with various properties, tailored to the specific application's requirements, including resistance to oils, greases, rodents, termites, UV and flame, as well as zero halogen emissions.
