Electronic Transformer Industry: Insulating bushings are commonly used insulating materials in electronic transformers, mainly used to protect the internal circuits of transformers. It can effectively isolate charges between different circuits inside the transformer, prevent leakage or short circuit phenomena, and ensure the normal operation of the transformer's internal circuits. Rongshibang silicone resin fiberglass tubes have excellent high and low temperature resistance, can maintain good elasticity and insulation performance in a wide temperature range, can adapt well to environmental changes, and ensure safe and reliable operation of transformers.
