GW9-12 High Voltage Disconnect Switch Power Disconnect Switch Thickened Channel Steel ertical Break Switch

Product Decription:

High Voltage disconnect switch is an electrical switch used to disconnect a circuit from its power source. It is typically used in high-voltage power transmission and distribution systems to allow maintenance personnel to safely work on the equipment without the risk of electrocution.

High Voltage disconnect switch has a blade or contact that can be opened or closed by rotating the pole, which engages or disengages the circuit. The pole usually has a non-conductive material to insulate the operator from the high voltage.

High Voltage disconnect switch come in various designs and sizes, depending on the voltage and current rating of the circuit they are intended to control. They are often mounted on a pole or a structure and are commonly used in conjunction with other protective devices, such as circuit breakers and fuses, to ensure the safety and reliability of the electrical system.

Feature:

1.Circuit Isolation: High voltage isolator switches are used to isolate a section of a high voltage circuit for maintenance, repair, or testing purposes. By opening the switch, the section can be effectively disconnected from the rest of the system, allowing work to be carried out safely.

2.Load Switching: High voltage isolator switches can be used as load switches to control the flow of electrical power in a circuit. They are particularly useful in situations where the load is relatively small and does not require a circuit breaker or fuse.

3.Overhead Line Protection: High voltage isolator switches are often installed on overhead power lines to provide protection against lightning strikes and other electrical disturbances. By isolating a section of the line, the switch can help prevent damage to equipment and reduce the risk of power outages.

4.Transformer Protection: High voltage isolator switches are also used to protect transformers by isolating them from the electrical network in the event of a fault or overload. By opening the switch, the transformer can be disconnected from the network, preventing damage to the transformer and other equipment.

Advantage

1.Simple structure: The isolation switch is designed with a straightforward structure, making it easy to understand and operate.

Low maintenance: Due to its design and construction, the isolation switch requires minimal maintenance, reducing the need for frequent inspections and repairs.

2.High breaking and closing linearity: The isolation switch has excellent breaking and closing linearity, ensuring smooth and reliable operation during switching operations.

3.High reliability: The switch is built to provide dependable performance, minimizing the risk of malfunctions or failures during operation.

4.Comparable to international standards: The GW9-12(W) series isolation switch meets or exceeds the level of similar products both domestically and internationally, ensuring its compatibility and competitiveness in the market.

Structure:

1.Porcelain Insulator Body: The insulator body is the main component of the isolator, and is typically made of high-strength porcelain. It is designed to provide electrical insulation between the conductor and supporting structure, and is molded into the desired shape and size.

2.Metal End Fittings: The metal end fittings are attached to the insulator body and provide a means of connecting the isolator to the conductor and supporting structure. They are typically made of galvanized steel or other corrosion-resistant material, and may be designed with special features such as clevises or ball-and-socket joints for easy installation.

3.Sealing Compound: A sealing compound is used to seal the joint between the insulator body and metal end fittings, preventing moisture and contaminants from entering the interior of the isolator.

4.Hardware: Hardware such as bolts, nuts, and washers are used to secure the metal end fittings to the insulator body and supporting structure.

Fitting Caps: Fitting caps are used to protect the metal end fittings from corrosion and damage, and may be made of plastic or other materials.

5.Additional Features: Depending on the specific application, porcelain high voltage electrical isolators may be designed with additional features such as insulating barriers, arc chutes, and earth switches to improve their performance and safety.

Application:

1.Circuit isolation: High voltage electrical isolators are primarily used to isolate sections of a power system for maintenance or repair work. This allows workers to work safely on the isolated circuit without the risk of electrocution or other electrical hazards.

2.Safety: High voltage electrical isolators are also used as a safety device to protect workers and the public from electrical hazards. By isolating a circuit, High voltage electrical isolators prevent accidental contact with live parts of the system and reduce the risk of electrical accidents.

3.Fault protection: High voltage electrical isolators can also be used to protect the power system from faults, such as short circuits and overloads. By isolating a faulty section of the system, High voltage electrical isolators prevent the fault from spreading to other parts of the system and causing further damage.

4.Switching: High voltage electrical isolators can be used as a switching device to control the flow of power in a system. By opening or closing the isolator, the flow of power can be directed to different parts of the system as needed.

5.Testing: High voltage electrical isolators can also be used for testing purposes, such as to measure the voltage or current in a circuit, or to test the performance of other components in the system.
