1.General Description
ZCW8-126(L) open-type composite apparatus is a new-type product developed by PG?own for the development of power market. Compared with the same products abroad, it can fill the requirements of domestic power market. Our company can not only design flexible layouts according to the customers?requirements, but also be contracted to supply the primary apparatus of the whole substation.
ZCW8-126(L) open-type composite apparatus has advanced structure and good performance. Its technical data comply with GB and IEC standards. The product has the advantages of compactness and small area of GIS and low price and easy maintenance of open-type composite apparatus. Compared with general substation, its area decreases 60%. It is applied to the substations in the cities, mountains and mining industries in particular.
