Introduction to Composite Bushing
Composite bushings are crucial components in electrical power systems. They are designed to provide insulation and support for electrical conductors passing through various equipment such as transformers, switchgear, and circuit breakers. Made from composite materials, these bushings offer several advantages over traditional porcelain or oil – filled bushings. Composite materials, typically a combination of fiberglass and epoxy resin, provide excellent mechanical strength, high resistance to environmental factors like moisture, pollution, and UV radiation. They are also lighter in weight, which simplifies installation and reduces transportation costs. Moreover, composite bushings have better seismic performance, making them suitable for use in areas prone to earthquakes. Composite Bushing
