DIN 1kV 1000A 3150A Low Voltage Transformer Porcelain Bushing
The Threaded Bushings for voltage of 1kV 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.
