33kV Medium Voltage MV ABC Cable

What is 33kV Medium Voltage MV ABC Cable?

33kV Medium Voltage MV ABC Cable are a type of overhead electrical transmission line designed for distribution networks. These cables are bundled with insulation, which offers several advantages compared to traditional overhead lines with bare conductors.

This variation of overhead power lines uses the same principles as bundled conductors, except they are closer to each other until the point of contact, but each conductor is surrounded by an insulating layer (except the neutral line).

Applications of 33kV Medium Voltage ABC Cable

33kV MV ABC cable is used for fixed installations, such as electrical energy distribution networks or industrial facilities, that is placed indoors, exteriors, in tunnels, in cable trenches or directly on the ground, able to withstand external mechanical forces and certain tensile force.
