Unitised Substation

we are amongst the leading suppliers of unitised substation. our unitised substation is for voltages up to 36kv.tt. It is a fully equipped unitised substatlon (uss) that includes outdoor housing. Medium voltage switchgear, distribution transformen low voltage panel and apfcr panei (0ptlonai). Only the incoming & out going cables need to be connected at site and the site work is kept to an absolute minimum. the unitised substation is completely self-contained and is factory assembled weatherproof housing that is ready for placing into position upon a concrete base. Unitised substation is provided with four lifting eyes located on the mol for easy lifting and positioning the whole unit at the site by the use of crane. each substation contains three main equipment: transformer. Mv switchgear and lv switchgear each is contained in appropriate compartment. All compartments are individually accessible by their own door from outside. features
