Medium-voltage (MV) cables are designed for demanding industrial, commercial, and utility applications, withstanding harsh environments and various installation methods, including direct burial, conduit, open trays, and aerial runs. Transmit electricity from a high-voltage network to the next level of transformers, powering local districts, large facilities, and communities. MV cables supply power to heavy machinery, motors, and equipment in industries like petrochemical, steel, and mills. Used in wind farms and solar power plants to transmit energy from the generation site to the grid or storage systems. Power is supplied to electric railways and airports through these cables. MV cables provide power for mining equipment and operations in challenging environments. Used in these facilities for power distribution and pumping systems.
Primary Uses
Why are they used?
Higher power requirements
MV cables are needed for equipment that requires a higher voltage level but lower than the high-voltage lines that transmit power over long distances.
Durability and protection
MV cables are built to withstand harsh environmental conditions, extreme temperatures, and physical stress, offering enhanced mechanical protection and corrosion resistance.
Versatile installation
They can be installed in various ways, including direct burial, underground ducts, conduit, open cable trays, or aerial systems, depending on the specific application.
Safety features
Many MV cables include features such as copper screens for fault-current handling and electromagnetic shielding to ensure system stability and safety.
Key Features
The abbreviation XLPE stands for Cross-Linked Polyethylene.
Depending on the application, variations are applied to specific requirements.
These cables are manufactured in either:
Core Specifications
- Copper or Aluminium cores.
- Single or 3 cores.
- Armoured (3 cores SWA/ 1 core AWA) or Unarmoured.
Cable Screening
All XLPE Cables are screened.
Sheathing
The Sheathing can be either:
- FR (Fire Retardant),
- LH (Low Halogen), HFC or
- ZTX (ZeroTox or Halogen Free Cable).
Voltage Rating
Medium-voltage ranges from
6.6kV to 33kV.
