IT Safe operation of substations heavily relies on the superior insulation performance of high-voltage bushings. When purchasing substation-specialized bushings, focus on these core technical details:
- Insulation Body: Adopt capacitive core for internal insulation with stable insulating properties, meeting the long-term continuous withstand voltage operation requirements of substations.

- Coaxial Conductor Core: Manufactured with high machining precision and excellent concentricity, featuring strong current conduction capacity. It operates without overheating or corona generation, suitable for harsh working conditions inside transformers, wall penetration and other scenarios.
- Sealing Structure at Both Ends: Tight sealing design prevents water and moisture ingress into the bushing interior, avoiding insulation dampening and breakdown, applicable to both indoor and outdoor substation environments.
- Outer Insulation Shed Creepage Distance: Optimized shed profile and creepage distance deliver anti-pollution, rainproof and anti-condensation performance, effectively preventing outer insulation flashover in heavily polluted substation areas.
- Authoritative Test Certifications: Manufactured in strict accordance with IEC 60137 and GB/T 4109 standards, complete with type tests including partial discharge, power frequency withstand voltage, temperature rise and climatic aging, applicable for new-built, expansion and reconstruction substation projects.
We specialize in customized dry-type capacitive high-voltage bushings, with precision production of high-voltage wall bushings and transformer bushings to guarantee stable and reliable power grid power transmission.
