High Voltage Disconnect Switch GW9-10 Series 1250A Vaccum Disconnector Used With Circuit Breaker For Outdoor
Product Description:
GW9-10 Series high voltage disconnect switch is a portable, high-voltage electrical switch used to isolate electrical circuits for maintenance and repair purposes. It is typically used in medium to high voltage power transmission and distribution systems.
The Loadbuster Electrical Isolator is designed to be portable and can be easily transported to the location where it is needed. It is capable of handling high voltage levels, typically ranging from a few kilovolts to several hundred kilovolts.
The switch is used to isolate a section of the power system for maintenance or repair purposes. It has visual indicators that show whether the switch is open or closed, making it easier for operators to know the status of the circuit.
The Loadbuster Electrical Isolator can be used for a wide range of applications, including switching and isolating circuits, as well as for grounding and de-energizing equipment. It is designed with safety features to protect operators from electrical hazards, such as insulating materials that prevent accidental contact with live parts.
The switch is easy to use and requires minimal training to operate. It has interchangeable blades that can be easily replaced, allowing for greater flexibility and versatility.
Application:
1 Substation isolation: In a substation, high voltage disconnector switches are used to disconnect transformers, circuit breakers, and other equipment from the power system for maintenance or repair.
2 Transmission line isolation: High voltage disconnector switches are used to isolate sections of a high voltage transmission line for maintenance, repair, or to prevent power flow during emergencies.
3 Capacitor bank switching: In power systems with capacitor banks, high voltage disconnector switches are used to disconnect the capacitor bank from the power system for maintenance or repair.
4 Load shedding: In case of an overload or other emergency situation, high voltage disconnector switches can be used to shed load by disconnecting certain sections of the power system.
5 Fault isolation: High voltage disconnector switches are used to isolate faulted sections of the power system to prevent damage to equipment and ensure continuity of power supply.
Conditions:
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
