Product Highlights
Engineered for Peak Performance
It has passed insulation parameter tests exceeding the standard requirements. The absence of a horizontal insulator beneath the moving parts reduces the risk of insulation faults such as the accumulation of metal particles. The design of the self-energy plus compressed-air hybrid arc extinguishing chamber requires low operating energy, reduces driving impact, and enhances both insulation and mechanical reliability.
Built for Operator Convenience
All operating mechanisms are arranged in a low position to improve the convenience of on-site operation, maintenance, and repair.
Proven Across Demanding Conditions
Through targeted design and extreme working condition testing, it can operate stably and meet the requirements of complex outdoor scenes in environments with strong sandstorms and large temperature differences.
