IFlexCable’s medium voltage power cable (MV power cable) is engineered for safe, efficient power distribution in industrial networks, renewable energy installations, and infrastructure projects up to 36kV. XLPE insulated with copper or aluminum conductors and steel wire armor options for demanding installations.

What Is Medium Voltage Power Cable?

Medium voltage power cable refers to cables rated from 1kV to 36kV used for power distribution between substations, transformers, switchgear, and large industrial loads. These cables feature cross-linked polyethylene (XLPE) insulation for superior thermal and electrical performance compared to older PVC-insulated designs.

IFlexCable’s MV power cable range covers 3.6/6kV, 6/10kV, 8.7/15kV, 12/20kV, and 18/30kV voltage classes, with single-core and three-core configurations for distribution network applications worldwide.

Applications

• Power distribution networks — Urban and industrial electrical distribution
• Renewable energy installations — Wind farm and solar farm grid connections
• Industrial plant power distribution — Factories, data centers, and manufacturing facilities
• Infrastructure projects — Tunnels, railways, airports, and hospitals
• Switchgear and transformer connections — MV/LV substation wiring
• Mining operations — Underground and open-pit power distribution

Construction

How to Select Medium Voltage Power Cable

Choosing the correct MV power cable requires matching several parameters to your installation:

• Voltage class — Select based on your system voltage with adequate design margin (e.g., 6/10kV cable for 6kV systems)
• Current rating — Calculate based on installation method (direct burial, conduit, air) and ambient temperature
• Conductor material — Aluminum is cost-effective for long runs; copper offers better ampacity and termination compatibility
• Armor type — Steel wire armor (SWA) provides mechanical protection for direct burial and areas with ground movement; aluminum armor (AWA) is non-magnetic and preferred for AC systems

Frequently Asked Questions

What is the difference between low voltage and medium voltage power cable?

Low voltage (LV) power cables are rated up to 1kV and used for final power distribution to buildings and equipment. Medium voltage (MV) power cables are rated from 1kV to 36kV and used for power distribution between utility substations, large transformers, and main switchgear. MV cables require thicker insulation, larger conductor sizes, and more rigorous testing than LV cables.

Can medium voltage cable be installed underground?

Yes. XLPE-insulated SWA (steel wire armored) medium voltage power cable is specifically designed for direct burial installation. The steel wire armor provides mechanical protection against digging and ground movement. Cable with PVC outer sheath is used for standard burial; polyethylene (PE) sheath is preferred for wet or corrosive soil conditions.

What certifications does IFlexCable’s medium voltage cable have?

Our MV power cables are manufactured to IEC 60502-2 and IEC 60840 standards, with CE certification for European markets. We also support country-specific certifications including SABS (South Africa), SASO (Saudi Arabia), and other destination market requirements.
