IEC BS Standard 12-20kV-XLPE Insulated PVC sheathed MV Power Cable

IEC BS Standard 12-20kV-XLPE Insulated PVC sheathed MV Power Cable

Specifications:

    Suitable for energy networks such as power stations. For installation in ducts, underground and outdoor.

    There’s huge variations in construction, standards and the materials used – specifying the correct MV cable for a project is a matter of balancing the performance requirements, installation demands, and environmental challenges, and then ensuring cable, industry, and regulatory compliance. With the International Electrotechnical Commission (IEC) defining Medium Voltage cables as having a voltage rating of above 1kV up to 100kV that’s a broad voltage range to consider. It’s more common to think as we do in terms of 3.3kV to 35kV, before it becomes high voltage. We can support cable specifications in all voltages.
