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.

Outdoor High voltage isolation switch with fuse
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.
China Outdoor High Voltage Three Phase Disconnector Switch
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.
15KV 600A Single Phase Disconnecting Standard Type Porcelain Isolate Switch
a piece of electrical equipment that safely disconnects specific high-voltage electrical network segments when there is no more current flowing through them. It is feasible to reduce the complexity of switching point and transformer substation layouts and do away with costly high-voltage circuit breakers by utilizing isolating switches, either by themselves or in conjunction with high-speed short-circuiting devices.
- Model GW9-15/600
Single Phase Disconnecting Porcelain Isolate Switch
An electrical device that, when no current is present, reliably disconnects certain areas of a high-voltage electrical network. The configuration of transformer substations and switching points can be made simpler by using isolating switches, either by themselves or in conjunction with high-speed short-circuiting devices. Additionally, high-voltage circuit breakers can be removed, saving money.
- Model GW9-27/600
Air-Blast Load Break Switch
Electrical appliances with a compressor load switch-fuse combination are appropriate for three-phase power distribution systems operating at 12 kV or less. They can be used to control and safeguard power equipment, including transformers, cables, overhead lines, and other equipment. They are particularly well-suited for use in box-type substations and the terminal substations of both urban and rural power grids. Additionally, it works well with double radiation power supply units and ring networks for safety and control.
