            YB□22

            Prefabricated substation

            YB/22 series preinstalled type transformer substation is my company to meet the demand of network construction, design and development of series products. This series of products is a kind of medium voltage switchgear, transformer, low voltage power distribution equipmentin a certain connection scheme combined into one of the sets of power aistribution equipment. This series of pre-loaded type is applicable to 12 kv substation, three-phase ac system rated frequency 50 hz, under 2000 kva capacity configuration of residential quarters, shopping malls hotels, large construction site, high mansion building. industrial and mining enterprises and temporary construction sites, suitable for ring network power supply. and optimum radial terminal power supply. The series preinstalled type substation has compact structure, complete sets of strong. safe and reliable operation, easymaintenance. the advantages of aesthetically pleasing: Selectivity has small volume, cover an area of an area small, big, small amount of on-site installation and short installation period, and it can move along with the load center, etc.
