Medium-Voltage Epoxy Support Insulators
ESI-101, ESI-201, ESI-202, ESI-301, ESI-302
Intended for 12 kV, 24 kV, or 36 kV power systems, these support insulators, also called “post insulators,” are cast in Araldite® epoxy resin. With excellent resistance to moisture, these easy-to-install insulators can be used in locations with salty or polluted air.

Epoxy Insulator Accessories for Medium-Voltage C-GIS
Epoxy resin insulator accessories play a crucial role in C-GIS, which is short for cubicle-type gas-insulated switchgear—a type of gas-insulated switchgear (GIS). These insulator accessories are integral to the metal-enclosed switchgear equipment that is insulated with sulfur hexafluoride (SF6) gas.

Epoxy Resin Insulators & Epoxy Bushings
Epoxy resin insulators and bushings find applications across a wide spectrum of uses. With over three decades of experience, Challenge Industrial Co., Ltd. (CIC) has been dedicated to the research and manufacturing of these vital insulation components. In 1990, CIC incorporated cutting-edge "Automatic Pressure Gelation" (APG) equipment, molds, and associated hardware sourced from Vogel in Switzerland, facilitating the creation of a mechanized production line for resin insulation products. Building upon its extensive knowledge in producing medium-voltage distribution box insulators, such as support insulators and wall bushings, CIC has developed a diverse range of high-precision insulation products, which are employed in various electrical distribution equipment and associated engineering projects. Today, CIC offers a wide array of epoxy resin insulation solutions, including indoor and outdoor post insulators, wall bushings, bushing plates for busbars, MV voltage monitoring insulators, and various insulation accessories for 12-36 kV distribution equipment. CIC's product portfolio extends to medium-voltage C-GIS insulator components, VCB frames for 24 kV vacuum circuit breakers exported overseas, 24 kV single-phase gas circuit breaker insulator housings for high-speed railway trains, support insulators for gas-insulated bus ducts in local high-voltage substations in Taiwan, GIS spacers for 220 kV gas-insulated switches, and more. As the first manufacturer in Taiwan to establish a resin insulation production line using equipment imported from Switzerland, CIC utilizes Huntsman Advanced Materials' Araldite® epoxy resin (formerly under Swiss Ciba-Geigy). With decades of production expertise, CIC’s epoxy resin insulators and bushings are widely trusted by local distribution board manufacturers, transformer factories, and power companies. Their reputation for superior quality has led to widespread adoption by numerous international companies and clients in Europe, America, Japan, and other countries. CIC provides a diverse product range tailored to the needs of distribution equipment manufacturers, power engineering contractors, Taiwan's nuclear power plants, high-speed railways in Japan and China, and various international large-scale public engineering projects, offering customized insulation solutions.
