Protection Relay Compare with switching type relays, our protection relays have a clearly defined operating voltage and other operating parameters. They are composed of arrays of induction disks, shaded-pole magnets, operating and restraint coils, solenoid-type operators, telephone-relay style contacts, and phase-shifting networks.

A breaker switch is also known as a load break switch. It is a switching device that can close and discontinue the load current, field current, charging current and current of the capacitor bank in normal operating condition. The commonly used break switches include vacuum load break switches, outdoor load break switches and indoor load break switches. According to the working voltage, load break switches can be grouped into high voltage load switches and low voltage load switches. The operating principle of high voltage load switches is similar to breakers. They are generally equipped with an arc control device with simple structure.

Huayi Electric Co., Ltd. is an ISO9001: 2000 and ISO14001: 2004 certified load break switch manufacturer in China. We can provide various outdoor load break switches and indoor load break switches. The raw materials used in the manufacture of our products have been strictly inspected in order to ensure high performance. Besides load break switches, we also produce wind turbine generators, circuit breakers, disconnect switches and other products.

Low Voltage Components Disconnect switches generally refer to high voltage disconnect switches with 1Kv or above rated voltage. In the circuit, disconnect switches have the function of isolation. They are the most commonly used switches among all high voltage switching apparatus. Its operating principle and structure are simpler...
