24 Kv Pole Mounted Vacuum Circuit Breaker

ZIKAI® warmly welcome you to buy 24 Kv Pole Mounted Vacuum Circuit Breaker from our factory. Our products are CE certified and currently have a large amount of factory inventory. We will provide you with good service and factory discounted prices.

ZIKAI® is 24 Kv Pole Mounted Vacuum Circuit Breaker manufacturer and supplier in China, we can provide professional service and better price for you. 24Kv Pole Mounted Vacuum Circuit Breaker (VCB) is a kind of switch equipment used in power system, the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are high vacuum. This circuit breaker is specially designed for use in three-phase AC (AC) 50Hz power systems with a rated voltage of 24kV for control and protection circuits. Because vacuum is used as the extinguishing medium, it has the characteristics of small size, light weight, suitable for frequent operation and no frequent maintenance.

Zi Kai 24 Kv Pole Mounted Vacuum Circuit Breaker Application

Distribution network:

In the distribution network, the 24kV vacuum circuit breaker on the column is used as a key control and protection element for the distribution and transmission of electrical energy. They are installed on utility poles so that the circuit can be quickly cut off or switched on when needed, protecting downstream equipment and lines from failures such as overload and short circuits.

Substation and switchboard:

In substations and switchboards, circuit breakers are used as incoming and outgoing line switches or bus-block switches to achieve control of different power circuits. They can quickly respond to system instructions under automatic or manual operation to achieve reliable circuit switching.

Industrial and commercial electricity:

For large industrial and commercial facilities, such as factories, shopping centers, hospitals, etc., 24kV vacuum circuit breakers on columns are widely used in power distribution systems. They ensure the stability and reliability of the power supply, while being able to quickly cut off power in the event of a failure, protecting equipment and personnel.
