10KVSTANDARDIZED DISCONNECTOR POST PORCELAIN INSULATOR

This is a dedicated porcelain post insulator for 10 kV outdoor polemounted disconnectors complying with StateGrid standard requirements. It is applied in 10 kV AC distribution systems to provide electrical insulation and mechanical support for live parts of disconnectors.
Manufactured from highstrength electric porcelain, the insulator features high mechanical strength, excellent weatherproof & antipollution performance, reliable cemented structure and good interchangeability. It is suitable for outdoor overhead lines of urban and rural power distribution networks.

10KV STANDARD PORCELAIN INSULATOR FOR DROPOUT FUSE

This porcelain insulator is specially designed as insulating support for 10kV outdoor standardized dropout fuse. Made of highstrength alumina porcelain with glazed shed design, it serves for earth insulation and mechanical support for upper and lower metal contacts of fuse.
Complying with StateGrid standard for 10kV polemounted fuses, it features high mechanical strength, antipollution and thermal cycling resistance. Suitable for overhead distribution network and primary side of distribution transformer, with good interchangeability.

30KV PORCELAIN INSULATOR FOR VACUUM CIRCUIT BREAKER

Model 8646A+8647 is used as a set. 8646A is vertical insulator and 8647 is horizontal insulator for vacuum circuit breaker, applied to 30kV on-board vacuum circuit breakers installed in roof high-voltage boxes of high-speed trains. It provides mechanical support and earth insulation for high-voltage conductive circuits. Made of high-strength alumina porcelain with multi-shed anti-contamination glaze, it features outstanding vibration resistance, shock resistance, fatigue resistance and tolerance to tunnel condensation and dust. Adaptable to alternating vibration and temperature variation caused by high-speed operation and tunnel transit. The two types work in combination to meet high-reliability requirements of rolling stock on-board high-voltage equipment.
