Product Summary

The RMU is generally divided into air insulated and SF6 insulated types. XGN15- 12 indoor fixed type SF6 RMU uses SF6 switchas its main switch, and air insulation is used for the entire cabinet. It is suitable for 10kV distribution systems in factories, enterprises,residential districts, high-rise buildings, mines and ports. And it can be combined into ring network system used for power supplyand distribution of three-phase AC ring network, biradial power supply unit or line terminal,receiving, distributing and controllingelectric power, and protecting the safety operation of electrical equipment.


Environmental Conditions

1.Ambient Temperature: No more than +40℃ and no less than - 15℃Average temperature is no more than +35℃ within 24 hours.

2.Altitude: No more than 1000m.

3.Relative Humidity: the average daily value is no more than 95%, the average monthly value is no more than 90%.

4.Earthquake Intensity: No more than 8 degrees.

5.Vapor pressure: average daily value is no more than 2.2kPa, average monthly value is no more than 1.8kPa.

6.Installation locations without fire, explosion danger, serious pollution, chemical corrosion and violent vibration.


Product Features

1.Modular design. Each unit module can be combined and extended arbitrarily, which is easy to schemes combination, with a wideapplicable range.

2.The armored structure is used for the cabinet. And each compartment is separated to the other one by metal partition board.

3.The corrosion resistant metal is used for the operating mechanism, and bearings of rotating parts are all self-lubricating bearings.The product will not be affected by the environment, thus exempting from regular maintenance.

4.In order to adapt to the power grid automation and improve the reliability of power distribution, the electric drive mechanism, controlterminal unit of power distribution network and other equipment can be added. Thus, it possesses telemetering, remote signalingand remote control systems.

5.The cabinet is compact design, using three- positions rotary load switch, which effectively reduces the number of components andparts, and realizes the five-preventions interlocking.

6.The simulated single line diagram of primary circuit and analog display can display the internal conditions of the switch, so that theoperation can be simple, correct and safe.
