12kV/24kV PT Trolley

Short Description:

Application

The 24kV withdrawable transformer trolley has the characteristics of perfect design, compact structure, easy operation and excellent performance. It is suitable for high-voltage middle cabinets, where PT can be quickly drawn out and moved in to reduce the power failure switching time. The high-voltage fuse uses a miniature fuse with a diameter of 25mm and a length of 355mm, which is directly installed in the insulating contact arm. There are two sizes of PT vehicles, which are used in 800-wide cabinets and 1000-wide high-voltage center cabinets.
