Pillar - type fully enclosed structure with high sealing performance
Vacuum silicone grease is filled between the arc - extinguishing chamber and the insulating cylinder, which has good sealing performance, anti - aging and high - voltage resistance;
Vacuum arc extinguishing and vacuum silicone grease insulation are adopted, with good breaking performance and high safety and reliability;
It has a high insulation level, and a heater is installed in the box to prevent electrical components from getting damp, so that it can operate in high - altitude and low - temperature environments;
Effectively solve the problem of condensation and avoid defects caused by inflation and oil filling;
Long service life and low maintenance workload.
Specially equipped current transformer with multiple secondary windings, high precision and large capacity;
The current transformer can be installed either inside the box or outside the box.
Various convenient and flexible installation structures
The circuit breaker has various structures such as side - mounted type, middle - mounted type and built - in insulating pull rod, which is convenient for users to choose according to different installation locations.
