Product Details

GW9 Series High Voltage Disconnect Switch AC Powerful Group Disconneting Isolator
 
Product Decription:


 
GW9 Series High Voltage Disconnect Switch is an electrical switch that is designed to isolate a section of an electrical network or system from the rest of the system for maintenance or repair purposes. It is typically used in high voltage power transmission and distribution systems.
The switch is designed to open and close under normal or abnormal conditions, such as a fault or overcurrent. When the switch is open, it physically disconnects the section of the system from the rest of the network, preventing the flow of electricity to that section.
High voltage disconnect switches are typically designed to operate at voltages between 600 volts and 765,000 volts, and they can be operated manually or automatically. They are typically installed in substations or on power poles, and they are an important component of the electrical grid infrastructure.
It is important to follow proper safety procedures when working with high voltage disconnect switches, as they can be dangerous if not handled correctly. Only qualified and trained personnel should be allowed to operate and maintain high voltage equipment.
 
 
 
Application:


1.Maintenance and Repair: The Loadbuster Electrical Isolator is commonly used to isolate and ground electrical distribution lines for maintenance and repair activities. It allows maintenance personnel to work safely on energized equipment without the risk of electrocution.
2.Emergency Response: The Loadbuster Electrical Isolator can be used in emergency situations, such as power outages or natural disasters, to isolate and ground electrical distribution lines and restore power safely.
3.Switching Operations: The Loadbuster Electrical Isolator can be used to open or close switches and perform other switching operations on electrical distribution lines.
 
 
Condition:



1.The altitude does not exceed 1000m
2.The ambient air temperature: Maximum+ 40'C ;Minimum:General Area -30'C, Paramos -40 C;
3.The wind pressure does not exceed 700Pa.(corresponding to 34m/s wind speed);
4.The earthquake intensity does not exceed 8 degrees;
5.The working situation is without frequent violent vibration;
6.The installation site of ordinary type isolator should be kept away form gas, smoke chemical deposition, salt-spray fog, dust
and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator
7.Pollution-proof type isolator is applies to severe filthy conduction area, however, it shouldn't be any explosive matters and matters causing fire.
 
Safety risks:



1.Electrical shock: High voltage disconnect switches can deliver a potentially lethal electric shock if they are not handled properly. This can happen if the switch is not properly isolated before it is opened or if there is a fault in the equipment.
2.Arc flash: When high voltage disconnect switches are opened, an arc flash can occur, which can release a significant amount of energy in the form of heat, light, and pressure. This can cause burns, eye damage, and other injuries.
3.Equipment failure: High voltage disconnect switches can fail if they are not properly maintained or if they are overloaded. This can lead to equipment damage, electrical fires, and other hazards.
4.Environmental hazards: High voltage disconnect switches are often located in outdoor environments, where they can be exposed to extreme weather conditions, such as high winds, heavy rain, and lightning strikes. These conditions can create additional safety risks for personnel who are operating or maintaining the equipment.
 
P.S.
To minimize the risks associated with high voltage disconnect switches, it is important to follow proper safety procedures, including using appropriate personal protective equipment, following lockout and tagout procedures, and ensuring that only qualified and trained personnel are allowed to operate and maintain the equipment. Regular maintenance and testing of the equipment can also help to reduce the risk of equipment failure and other hazards.
