N2XS2Y 8.7/15kV

10 Min Read
8.7/15kV voltage rating is classified under Medium Voltage (MV), supporting heavy-duty equipment power and MV distribution on industrial sites, mining operations, and utility networks. 15kV is a voltage commonly specified for equipment cables, including robust mining equipment cables manufactured in accordance with IEC 60502-2, but is also associated with British standard armoured cables BS6622 and BS7835.

What is 8.7/15kV Cable?

mining cables may be sheathed in robust rubber to provide abrasion resistance, especially for trailing applications, the BS6622 and BS7835 standard cables are instead sheathed in PVC or LSZH materials, with mechanical protection provided from a layer of steel wire armouring. As a British standard voltage, 8.7/15kV isn’t as commonly specified as 11kV or 33kV, but will depend on the application demands.

IEC 60502 is an international standard published by the International Electrotechnical Commission (IEC) that sets out the specification for power cables with extruded insulation. The standard covers cables with voltage ratings from 1 kV (Um = 1.2 kV) up to 30 kV (Um = 36 kV), designed for fixed installations such as distribution networks and industrial installations. This widely recognized standard serves as a primary reference for cable manufacturers worldwide and forms the basis for numerous national and regional cable standards.
