Electrical Safety Devices

Copper remains the foundational raw material for electrical safety devices, primarily utilized in high-conductivity internal paths, contact points, and terminals of circuit breakers, fuses, and relays.

Silver and silver-based alloys serve as critical raw materials for contact tips in electrical safety devices due to their exceptional electrical conductivity and arc-resistance properties under extreme voltage failure conditions.

Engineering plastics, including thermosets and thermoplastics like polyamides and polycarbonates, are primary raw feedstocks required for structural insulation and injection-molded casings of electrical safety enclosures.

Upstream material supply chains face structural bottlenecks due to high dependencies on regional smelting and processing capacities, which significantly impact the final availability and pricing of localized power infrastructure equipment.
