In order to guarantee more reliable and stable operation of electric equipment for indoor or outdoor substations, GIS acts as an integrated switchgear that monitors, controls, protects and measures the power systems with protection & control relay panels by safe opening or closing the power lines under the conditions of normal and abnormal operations.
High Safety
With metal tank completely earthed and recharging section not exposed outside. not only capacitative induction and contact incident can be avoided, but also fire prevention is accomplishment by using flame retardant SF6 Gas. As controlling lever is not exposed outside, there is no danger to operator's body when controlling.
Easy Securing Area
LSIS's GIS takes much less area & space for installation than conventional type because of drastic reduction of required area for its compact size mainly by integrating all the components within the metal SF6 Gas filled-tank which is excellent for di-electric characteristics. It is suitable particularly in a dense areas like city and a place where large space and are not available.
High Reliability
Since main parts of switchgear is sealed with SF6 Gas it's free from environmental pollution and climatic change and there's no care about dielectric deterioration by long time operation. The diffusion of accident will be prevented by Gas Section in the case of internal accident. As the operating lever is designed to fit in such manner not to be exposed outside, malfunction caused by freezing and so on can be prevented. The merit when adapting an operating method by oil pressure is that it can be used almost permanently owing to the main components composed together within the oil which lessen the concern for aging and wearing off.
Easy Installation and Maintenance
Compact product size makes it possible to shorten the installation period remarkably due to its far more simple installation method than conventional type as well as for easy transportation to site. In addition, Installation without power shut down become possible for expansion works in the future and maintenance works is possible during operation because main components are concealed within SF6 Gas without being influenced by outside factors. Unlike pneumatic generator no regular check (more than 1 time a week) is required-featuring the maintenance free type.
