Product Details
Porcelain bushing in transformer is a core component for insulation and conductive lead-out of transformers, mainly used to lead the high and low voltage winding leads inside the transformer out of the oil tank, undertaking three core functions of conduction, insulation and mechanical support. The product is made of high-purity electrical porcelain material for the main insulation structure, assembled with high-quality conductive rods and seals. It is widely suitable for various oil-immersed transformers, and can meet the matching needs of transformers in power transmission and distribution, industrial and mining power distribution, power station transformation and other scenarios. As a key part to ensure the stable operation of transformers, it relies on excellent high-voltage insulation performance and reliable structure to effectively eliminate potential safety hazards such as transformer leakage and breakdown, and achieve stable power conduction and output. Featuring outstanding weather resistance and corrosion resistance, it adapts to complex outdoor operating environments stably.
