An operating mechanism is used to open and close the contacts. A valve controls the flow of SF6 gas between the two chambers. Our company offers a variety of electric operating mechanisms, which can be widely applied to medium and high voltage switch cabinets from ABB, Schneider, Siemens, etc.

This series of products has carried out standardized, integrated and modular design for the electric operating mechanisms and secondary circuits of ring main units (boxes). It can significantly reduce the on-site assembly and wiring time, and improve the delivery and operation efficiency of ring main units (boxes).

How we to Select the Model

Selection core: The three key factors for adapting to the requirements of switchgear equipment

1.Standard compliance: Our products that meet the standards of IEC and GB series ensure that the switchgear passes the type test.

2.Compatibility matching: Select products with appropriate torque and installation dimensions based on the circuit breaker model (such as Siemens 3VL, Schneider CM2);

3.Scene adaptability: For regular scenarios, Schneider is chosen (for its high cost-effectiveness); for extreme conditions, ABB is selected (for its strong protection); and for system integration requirements, Siemens is chosen (for its ecological compatibility).
