IEC/BS Standard 3.8-6.6kV-XLPE Insulated MV Middle Voltage Power Cable

IEC/BS Standard 3.8-6.6kV-XLPE Insulated MV Middle Voltage Power Cable

Specifications:

    3.8/6.6kV is a voltage rating more commonly associated with British standards, notably both BS6622 and BS7835 specifications, where applications can benefit from the mechanical protection provided by their aluminium wire or steel wire armour (depending on single core or three core configurations). Such cables would be well suited to fixed installations and providing power to heavy-duty static equipment as their rigid construction limits the bend radius.

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

    Please note: Red outer sheath can be prone to fading when exposed to UV rays.
