Based on the partnership with SIEMENS Inc. in German, one of leading companies in the
field of supply and monitoring equipment and continuous research and development, we provides 33SG gas insulated switchgears to domestic electric systems.
All the units of SF6 Gas Insulated Switchgear(GIS) from our company are equipped in a
grounded metal pressure vessel featuring the highest performance, high availability for real systems and detachable danang, and its main circuit is insulated by an inactive gas, SF6 having no color, taste, odor and toxicant .
In addition, it has a built-in vacuum breaker to cut off the load current and failure current from the circuit, and features high performance consistency and endurance for the long time operation. It also boasts semi- permanent lifetime and no needs to perform maintenance tasks, because its breaking unit sealed in a vacuum vessel guarantees no malfunction in GIS during repeated tasks to cut off the current
The highly experienced professional group in our company expects the increased quality,
enhanced reliability and differentiated usage of domestic electrical systems, enabled by the strong customer support, and promises to deliver the 33SG GIS with the best quality satisfying customer needs. The features of our GIS are as follows.
25.8kV Gas Insulated Switchgear with single bus, developed with our continuous research
and development, will be provided to domestic and international markets
All the units of SF6 Gas Insulated Switchgear(GIS) from our company are equipped in a
grounded metal pressure vessel featuring the highest performance, high availability for real systems and detachable single pole metal-enclosed , and its main circuit is insulated by an inactive gas, SF6 having no color, taste, odor and toxicant.
High Reliability
All the components sealed with SF6 gas guarantees no deterioration and semi-permanent high performance
Safety
Active units built in the grounded metal case ensures the safety of workers during operation and maintenance
Convenient Maintenance
Due to no deterioration at the components surrounded by SF6 gas, long term ? based maintenance is enough to ensure the compatibility for the product maintenance.
Reduced Installation Area
The effective installation area, enabled by reducing the width of unit circuit which determines the installation area.
Reduced Plan and deployment time
Reduced planning, manufacturing and delivery time, enabled by a combination of standard components
Environment- friendly combination
Superior modern environment-friendly combination featuring its tidy figure, low noise, minimized induction fault.
