Why power utilities choose InsulatorX
01
UHV-class engineering
Validated to ±1100 kV DC and 1000 kV AC transmission classes with full type-test reports.
02
Vertically integrated manufacturing
From clay slurry to final shed glaze, every step happens under one roof — for traceability and consistent quality.
03
Global compliance
IEC 60305 / 60372 / 60383, ASTM, ANSI C29, GB/T 7253, BS, JIS — type-tested at independent labs.
04
Field-proven longevity
Installed base across coastal, desert, high-altitude and heavy-pollution corridors with 30+ year design life.
Inside the factory
A purpose-built porcelain campus
Our 120,000 m² Pingxiang facility houses raw material prep, a 125-meter gas-fired tunnel kiln, high-volume pressing, automated dimensional inspection and the high-voltage testing center — all under one roof.
