MV-Underground Power Cable

Introduction​​

MV-power cable

ZMS cable manufacturer as a professional medium voltage underground power cable supplier. Our standard medium voltage underground transmission line composition includes single and triple core copper or aluminum conductor cables. Also including polyvinyl chloride (PVC), crosslinked polyethylene (XLPE), polyethylene (PE), ethylene propylene rubber (EPR), and Low-pressure halogen-free (LSZH) jacket performance. As well as steel wire armor or aluminum wire armor to increase mechanical strength and provide mechanical protection.

Custom Medium Voltage Cable

In addition to standard MV cable products, we can also customize MV cables for you based on your specific application needs. Our custom cable solutions can be developed and designed around a variety of parameters and manufacturing variants. Include:
Cross-Sectional Area: usually 35mm2 to 630mm2
Number of Cores: single core or triple core.
Conductor: solid or stranded aluminum conductor, stranded copper conductor.
Insulation: XLPE (usually used as a medium voltage cable) or EPR (because it is relatively flexible, it is often used in marine or marine applications).
Metal Shield: concentric copper wire screen, aluminum foil laminate, extruded lead alloy sheath.
Armoured: Aluminum tape armor is mainly used for single-core cables, and galvanized steel wire armor is mainly used for multi-core cables.
Outer Sheath: We can tailor it to specific requirements. Cable jacket materials include PVC, EPR, LSZH, etc, to meet different environmental requirements.

Description of ZMS Cable Products

There is always some ambiguity in the range of voltage levels for medium voltage underground transmission cable. It depends on the country, as well as the standards-appointed bodies. We consider transmission lines with medium voltage levels above 3KV and below 35KV.
