YBM-12(24)/0.4 Pre-installed substation
YBM Pre-installed substation (also called European type substation)is connected separately by the cable or electric bar in the HV. Switch equipment, voltage transformer and LV. Electrical distributor. It has been used the normal indicated components in all of the HV & LV electrical distributors and transformers. The intellectual Preinstalledsubstation series can combine the HV switch equipment, which is RM6 or SEG switch with the automaticremote control electronic unit, transformer, LV. Electrical distributor, LV. Intellectual switch and no power automatic compensation into one unit, which has been fulfilled the site control or remote control, remote measure, remote counting. remote adjusting and any other functions. It suits for using in the public electrical distributing net, RMU, terminals such as residential quarters, enterprises, high buildings, airports and other places, which has a rated voltage up to 12kv,ratedfrequency 50Hz,three phases AC, System and capacity up to 2000kVA.
Notice to orderer
1.Model,specification,wire connecting mode of the transformer.
2.The main HV & LV wire connecting chart and the parameters of the main electronic compo-nents.
3.Whether shall the load switch equip with the electrical operating mechanism or not.
4.Inlet cable section.5.Any other specific requirement should be declared with the manufacturer.
