It should also have doors for transformer, L.V. cubicle and MV ring main unit with the necessary frame work to carry the whole equipment. The substation housing shall be made of three separate compartments: for transformer, MV metal enclosed RMU and LV panel. The housing shall be adequately ventilated and yet shall be so designed that birds, lizards and small rodents etc., cannot gain access to the equipment. Steel meshes behind louvers should be used for this purpose. Compact Ring Main unit with LV board both directly coupled to the transformer could be accepted if the Tenderer proves suitability for outdoor use without the need of housing.
