Wall bushing is an insulation component used in power systems to guide high-voltage wires through building structures such as walls and floors. It is mainly composed of conductive poles, insulation media (such as porcelain, epoxy resin, or silicone rubber), and metal flanges. Its core function is to isolate charged bodies from buildings while ensuring reliable transmission of electrical energy. Its advantages include: using high-strength insulation materials, withstanding voltages up to 10-220kV, possessing impact resistance, corrosion resistance, and aging resistance, and being able to adapt to complex environments such as high temperature, humidity, and dust; Optimize the electric field distribution in structural design, ensure that the creepage distance meets the pollution level requirements (such as Level II-IV), and reduce the risk of flashover; The metal flange is tightly matched with the wall, supporting bolt fixation or concrete pouring installation, with excellent sealing performance to prevent rainwater and small animals from entering.

We provide a full scenario solution: customized sleeve specifications based on wall thickness, voltage level, and installation method (indoor/outdoor), supporting various materials such as copper and aluminum conductors; Strictly follow standards such as GB/T 12944 and IEC 60137, and ensure insulation performance and mechanical strength meet standards through tests such as withstand voltage and temperature rise; Provide installation guidance and waterproof sealing solutions to assist customers in efficiently completing through wall wiring. The company relies on 15 years of experience in the research and development of power fittings, automated production lines, and a national warehousing network to provide high-precision and long-life through wall conduit products for scenarios such as substations, industrial plants, and high-rise buildings, ensuring the safety of power transmission and reliable isolation of building structures.
