GIS GAS Insulated switchgear For Transportation

GIS GAS Insulated 4 Phase Protection Low Voltage Switchgear for Transportation​



Product Description


  • Low-voltage switchgear is typically used for power systems with a voltage of less than 1000V. It is used to control and distribute power to electrical loads while protecting them from overcurrent and other electrical faults.


  • Fixed type switchgear is often used in indoor applications where space is limited, while movable type switchgear is usually used in outdoor applications where flexibility is required.


  • Drawer type switchgear is designed with withdrawable units that can be removed for maintenance or replacement without interrupting the power supply to other equipment.


  • Modular type switchgear is made up of standardized modules that can be easily combined to create customized switchgear assemblies.


  • Isolated type switchgear is designed to provide a high degree of safety by isolating the electrical components from the operator.


  • Explosion-proof type switchgear is used in hazardous environments where there is a risk of explosion due to the presence of flammable gases or dust.


  • Protective type switchgear is used to protect electrical equipment from damage caused by overvoltage, undervoltage, or other electrical faults.


  • Low-voltage switchgear must meet several international standards and regulations, such as IEC 61439, UL 891, and GB7251.
  • Switchgear should be designed with clear labeling and color-coding to make it easy for operators to identify different components and functions.
  • Regular maintenance and testing of low-voltage switchgear is essential to ensure its continued safe and reliable operation.


Overall, low-voltage switchgear plays a vital role in modern electrical systems, providing a safe, efficient, and flexible solution for power distribution and control in a wide range of applications.
