main product features:
1. high technical parameters. it meets the requirements of iec 62271-1 and iec 62271-100.
2. the operation mechanism adopts the modular design. the valve system of this type of hydraulic mechanism adopts the integrated block structure, which is small in size and compact in structure. it not only maintains the reliable characteristics of the hydraulic mechanism such as fast movement, stable characteristics, low noise and no wear and tear, but also completely avoids the leakage of the mechanism.
3. the product is designed for the environment in northwest china, with the highest altitude of 2,000 meters in the applicable area, covering most of northwest china. a 0.5 mpa circuit breaker is specially designed for the northwest low temperature region, and users can choose according to different needs.
