Gas Insulated Switchgear (GIS)

Product Description

1.Introduction
ZF48-126 (145) type GIS switchgear is assembled from different standard functional modules, namely,
circuit breaker GCB, Combined Diconnector/Earthing Switch TPS, potential transformer PT, current
transformer CT, SF6/air bushing BSG and busbar BUS, etc. Every module uses a common enclosure for
the three phases. All these modules have a common interface with the same dimensions, and thus can be
combined according to the design and layout requirements of various substations. Due to the modular
concept, maintenance is simplified and future retrofit or expansion of the substation becomes very easy.
The high degree of flexibility obtained by the modular design makes it simple and easy to cover all
customer requirements and substation layouts such as single/double-busbar configuration, direction of
incoming power lines or cables, building dimensions, accessibility, quick trouble shooting etc.
