MDK Density Switch(Medium Voltage/High Voltage)

These instruments are used to monitor SF6 gas density in sealed tanks. They are applied to indicate the gas density and to provide a signal outputs when the density reaches the set value. They are designed to monitor High Voltage systems. They can provide multiple solutions to support new substations and the intelligent transformation of existing substations.

Application of MDK Density Switch


  • SF6 Gas Insulated Switchgear (GIS)

  • SF6 Insulated Circuit Breakers

  • SF6 Insulated Pole-Mounted Switch

  • SF6 Insulated Transformers

  • SF6 Insulated Mutual Inductor

  • SF6 Insulated Busbar Systems


Features of MDK Density Switch


  • Gas compensation guarantees higher precision of the set point. 

  • The Micro switch enables normally open contacts and normally closed contacts freely switch to each other.

  • High resistance to shock 

  • Usually closed contacts do not set a false alarm due to vibration
