Medium-voltage switchgear – ERM6

Medium-voltage switchgear – ERM6 is a complete unit consisting of a three-phase AC single bus, double bus, and indoor bus sections. It is primarily used in power plants, medium and small-sized power plants, substations, high-rise buildings, industrial enterprises and mining operations, subways, and electrified railways, etc., for controlling, receiving, distributing, protecting, and monitoring the electrical power supply and energy system

Key Features of the Medium-Voltage Switchgear – ERM6

• Metal-clad sealing, using low-pressure SF6 gas inside as the insulating medium. The high-voltage components are waterproof, dustproof, unaffected by environmental conditions, and resistant to altitude variations. The switchgear is completely maintenance-free
• Uses a permanent magnet or spring-operated mechanism, with a sealed vacuum interrupter that ensures reliable switching, significantly reducing the number of parts and components
• Reliable operation in basements, plateaus, frozen ground, coastal areas, and other harsh environments, including humid and foggy conditions. It meets the power supply needs of new energy projects, plateaus, subways, high-speed railways, and urban electrical distribution projects with limited space. The switchgear is highly reliable, maintenance-free, adaptable, and occupies minimal space
• With an intelligent control and protection system, featuring robust control, protection, measurement, and communication functions, it fully meets the automation requirements of the distribution network

Applications of the Medium-Voltage Switchgear – ERM6

1. Circuit Interrupting: The switchgear can interrupt electrical circuits during faults such as overloads or short circuits, protecting the devices within the electrical system
2. Circuit Closing: The switchgear is capable of restoring power after the fault is cleared, ensuring continuous operation of the system
3. Protection: The switchgear integrates protection functions such as overcurrent protection, overvoltage protection, and short-circuit protection, preventing damage to equipment and the electrical network
4. Insulation: Uses SF6 (sulfur hexafluoride) gas as an insulating medium, ensuring high performance and reliability under various environmental conditions
5. Control and Monitoring: Equipped with measuring and signaling devices to monitor the operational status of equipment and the system

Environmental Conditions

• Altitude: Up to 5000m (If the equipment is installed at an altitude higher than 1000m, specific specifications need to be indicated).
• Ambient Temperature: Maximum temperature of 50°C, minimum temperature of -25°C. The average temperature over a 24-hour period should be less than 35°C.
• Relative Humidity: Average relative humidity for 24 hours ≤95%; average relative humidity for a month ≤90%.
• Installation Environment: No explosive gases, no corrosive gases in the surrounding air, and no frequent vibrations or strong impacts at the installation site.
