Compact Design Through State-of-the-art Technologies

A design highly optimized to provide maximum efficiency mechanically and electrically. Space-saving design is ideal for use in compact places especially in urban or industrial zone.

High Reliability

GIS is less affected from pollution, climatic changes and dielectric deterioration in consequence of time than air insulated switchgear(AIS). Our GIS is given early life test and full life test for customers to ensure safety and reliability.

Long Life and Minimal Operation Cost

From design to test operation, our GIS is fully tested and supervised to ensure maximum performance and highest level of quality. Built to last over 30years, it provides long service life at minimal operating cost.

Environmental Friendly

Minimal use of SF6 gas is realized by compact design and our high technology. Gas leakage barely occurs, so that much environmental friendly solution can be realized.

The operating mechanism for circuit breaker is spring stored-energytype that is installed in front of circuit breaker for easy access. The circuit breaker mechanism is composed of separate module whichmake it a simple design, highly reliable apparatus. The lifetime of circuitbreaker ensures over 20,000 use if mechanical life, with minimal use ofparts to ensure.
