Product Features
Compact Dimensions
Our 33 kv gas insulated switchgear (33 kv gis / 33kv gis switchgear) and supporting 36 kv switchgear - as high-performance gis switchgear tailored for enclosed power scenarios - are also professional 33kv indoor switchgear solutions. Adopting SF6 as the dielectric medium, this series of switchgear features a more compact structure compared with oil-insulated switchgear.
High Reliability & Safety
All live components and switching mechanisms of this 33kv gas insulated switchgear are hermetically sealed in an SF6-filled enclosure. Isolated from external environmental interference, the 33 kv gis delivers guaranteed reliability and safety performance – it is essentially maintenance-free, and eliminates risks of electric shock and fire hazards, which is a core advantage of this premium gis switchgear and dedicated 33kv indoor switchgear.
Easy Maintenance
With all live components and switching mechanisms sealed in the SF6 tank, the 33kv gis switchgear is resistant to corrosion and rust, significantly reducing routine maintenance workload. Additionally, a maintenance-free vacuum circuit breaker is integrated into this 36 kv switchgear lineup for further operational convenience.
Flexible Applicability
Featuring standard modular units and flexible combination modes, this versatile 33kv gas insulated switchgear (also known as 33 kv gis) can fully meet the application requirements of all power network nodes and end users. As a widely adaptable gis switchgear and 33kv indoor switchgear, it also covers the application demands of the 36 kv switchgear voltage level, achieving full-scenario coverage for medium-voltage power distribution.
