Model NO.: XGN75-12 Shell Material: Aluminum Alloy Installation: Fixed Current: AC Form: All- packaged Type Size: 1 Uint Shell Protection Grade: IP56 Trademark: TIANAN Origin: China Certification: VDE, CCC, ISO9001:2000 Voltage Level: Medium Voltage Structure: Fixed Board Type: Distribution Metering Box Operation Voltage: High Voltage Application Range: Power Plants Brand: Tianan Specification: IEC HS Code: 85372090 General
The Gas Insulated Switchgear designed for installation in Transformer Substation, industrial plants, and infrastructure & complies the most stringent requirement of
Safety in operation
Staff safety
Operation reliability
Smaller footprints
Reduced maintenance work
This Switchgear conforms to IEC 62271-200 and all primary components employed therein are in accordance with the relevant standards.
It is designed to accommodate high performance vacuum circuitbreaker (VCB) which has been designed and tested in accordance with IEC62271-100.
The switchgear panels are suitable for the assembly of single &double busbar systems for indoor installation.

Features:-
1. Reliable
Each compartment is monitored individually &has its own pressure relief device.
Use of Vacuum circuit breakers with high number ofmechanical & electrical operations
Robust interlocking system
2. Safety
The primary side components are hermetically enclosed, gas filled compartment and thus insensitiveto atmosphere, dirt &dust.
Current Transformer are mounted outside the gas compartment & mounted on earthed LV compartment
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
