Product Description

Switchgears for distribution
Model : Indoor SF6 gas insulated switchgear ring main unit 12kv/24kv/36kv
 

Product Overview
The SF6 gas insulated switchgear (GIS) is used for receiving and distributing electric energy in power system. It is widely used in processing industry, civil  and power supply terminal, such as: Small secondary distribution station,switching station,urban residential area,airport,railway and tunnel. It is equipped with perfect "Five Prevention" interlock device, which can completely eliminate personnel injury and equipment operation failure caused by human error operation.

Features
1.The gas insulated switchgear uses SF6 gas as arc extinguishing and insulating medium.
2.The switchgear is fully sealed and insulated, and the protection level reaches IP67.
3.The switchgear has reliable safe pressure relief channel, which can guarantee the safety of personnel even in extreme cases
4.The whole switchgear is not affected by the external environment.
5.Cabinet size is small, does not occupy space, and easy to install
6.The switchgear can be equipped with electric, remote control and detection devices according to different needs of users

Structure

Circuit breaker for inflatable cabinet
1. Fault Protection:It quickly interrupts electrical current during faults, such as short - circuits. This shields the power distribution system from excessive current damage, preventing widespread outages and protecting equipment.
2. Efficient Arc Quenching:Using SF6 gas, it achieves rapid arc quenching. The gas's excellent arc - extinguishing ability cools and extinguishes arcs fast, extending the breaker's lifespan and enhancing switchgear reliability.

SF6 gas tank
1. Exceptional Insulation:SF6 gas provides insulation 2.5 times stronger than air, effectively isolating live parts, thus preventing short - circuits and ensuring safe operation.
2. Powerful Arc - extinguishing:With arc - extinguishing capacity 10 times that of air, it quickly quenches arcs during switching, protecting internal components.
3. Superior Sealing:Tightly sealed, it stops gas leakage and keeps out impurities, maintaining stable performance and reducing maintenance needs.

Cable accessories for option

1. European front connector:Used for connecting cables to the front of electrical equipment, providing a reliable electrical connection with good insulation.
2. European style rear connector:Installed at the rear of electrical devices, it connects cables, often working with front connectors for loop - network cable connection.
3. European lightning arrester:Protects electrical equipment from over - voltages like lightning and switching surges by diverting them to the ground.
4. Current transformer:Transforms large currents into smaller ones proportionally for easy measurement, protection, and control in power systems.
5. Gas filled bushing:Serves as an insulating connection between the inside and outside of electrical equipment, with excellent insulation due to gas - filled design.
6. Insulation cap:Protects the end of electrical equipment from external contact with live parts, offering insulation and safeguard.
7. Top busbar connector:Connects busbars, ensuring electrical connection and current transmission with good conductivity and mechanical strength.
8. Voltage transformer:Reduces high voltage to a lower level in proportion, allowing safe monitoring of primary circuit voltage by secondary equipment.
