Product Description

GIS-Gas Insulated Switchgear
NINGBO TIANAN (GROUP) CO., LTD.

General
The GIS is suitable for power plant, substation, combined substation and electric power system, which is three phase indoor AC single busbar and sectioning single busbar with 50Hz, 35kV rated voltage, used to control, accept and distribute electric power.
Standard
>>IEC 60265-1, IEC 6227-1, EC 62271-100, -102, -105, -200 and IEC 60529 
Available modules
>>C:  Cable Switch
>>De:  Direct Cable Connection with earthing
>>D:   Direct Cable Connection
>>F:    Switch-Fuse Disconnector
>>V:   Vacuum Circuit breaker
>>Be:  Busbar earthing
>>Sl:   Busbar Sectionalizer, load break switch
>>Sv:  Busbar Sectionalizer, vacuum circuit breaker
>>CB: Circuit-breaker module
>>M:   Metering Module
>>Mt:  Metering tariff module
Functional design
1. Reliable
  Each compartment is monitored individually & has its own pressure relief device.
2. Safety
 The primary side components are hermetically enclosed, gas filled compartment and thus insensitive
  to atmosphere, dirt &dust.
3. Space saving
  Smaller foot prints All operations on the switchgear front.
4. Economically efficient
  Reduced space & surface area requirement. Long service life Maintenance free Gas compartment.
