1.2 KV417 A BIL 30KV ANSI Spade 4 Hole Porcelain Bushing Transformer Insulator
- Details
The Threaded Bushings for voltage of 1.2kV are supplied assembled with the respective porcelain, NBR gaskets, copper threaded rod, blued steel spin grip nut, zinc-plated brass connector and stainless steel lock washer and nut.
Low-voltage transformers with separate leads normally have solid porcelain bushings. These bushings consist of high-grade porcelain cylinders through which the connections pass. The outside surface may be plain or have a series of corrugations or skirts to increase the surface leakage path to the metal case. When the conductors are brought to the transformers in lead-covered cables, the leads often enter through cable terminators. These terminators are similar to ordinary potheads and are attached to the transformer with the bushings inside the case.
