China Isolate Disconnector Switch Factory
High voltage Isolate Disconnector Switch has several roles below,
1. The high-voltage isolating switch can ensure the safety of high-voltage electrical appliances and devices during maintenance work. It can play the role of isolating voltage, and cannot be used to cut off, input load current and break short-circuit current. It can only be used for certain switching operations that do not produce strong arcs, that is, there is no arc extinguishing function.
2. According to the installation location of the high-voltage isolating switch, it can be divided into indoor type and outdoor type. According to the number of insulating pillars, it can be divided into single-column type, double-column type and three-column type. There are optional equipment for each voltage level.
3. The contacts of the high-voltage isolating switch are all exposed to the air, and there is an obvious disconnection point. The isolating switch has no arc extinguishing device, so it cannot be used to cut off the load current or short-circuit current. Otherwise, under the action of high voltage, the disconnection point will produce a strong arc, and it is difficult to extinguish by itself, and may even cause arcing.
4. The high-voltage isolating switch can also be used to switch certain circuits to change the operation of the system. For example, in a double-bus circuit, the high-voltage isolating switch can be used to switch the running circuit from one bus to another.
"JECSANY" Isolate Disconnector Switch has stable quality and the products are exported to Southeast Asia, South Africa, South America, the Middle East and other global markets. OEM customization can also be made according to the drawings or samples provided by customers.

Pole-mounted Disconnector Switch 33KV
Model:HRH-B/33F-630-25kA
Pole-mounted Disconnector Switch 33KV is an electrical device for the reliable disconnection of certain sections of a high-voltage electrical network when there is no current in them. The use of isolating switches (either alone or in combination with high-speed short-circuiting devices) makes it possible to simplify the arrangement of switching points and transformer substations and to eliminate expensive high-voltage circuit breakers.
In the case of damage to certain sections of a network, the circuit breakers operate first, and then the isolating switches automatically disconnect the damaged section, after which the circuit breakers close again and restore electric power to the rest of the consumers on the network. Isolating switch......
