Medium Voltage cables, or MV cables, is a category defined by the International Electrotechnical Commission (IEC) as having a voltage rating of above 1kV up to 100kV. There does, however, remain some ambiguity over where the medium voltage cable band begins and ends, depending on the countries, the standard setting bodies, and the type of system used as historically engineers only referred to low voltage and high voltage. The concept of medium voltage was only introduced as the level of voltages increased and the need arose for a greater classification range, which now often includes extra low and extra high voltage.
Hongda Cable is a good supplier of medium voltage cables, which we consider to range between 3.3kV and 45kV. 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.

In addition to standard medium voltage cables, we can design and supply bespoke MV cable products developed for your specific applications. Our custom designed cable solutions provide for variants developed and manufactured around a number of parameters, including:
| Cross-sectional area: | generally 35mm2 up to 1000mm2 |
| 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. |
