FIELD: electrical engineering. ^ SUBSTANCE: invention relates to electric power engineering and can be used in construction of electrical installations designed to be incorporated with the industrial circuits rated at not over 110 kV. The electrical installation comprises a bearing structure representing a block-box with lateral and front walls, a floor, a roof and doors. A 35 to 110 V non-oil-filled electrical hardware is mounted on the said block-box roof. The electrical hardware inside the block-box is mounted so that a free part of the floor is intended for servicing personnel. The proposed block-box allows adding several block-boxes to abut on the end face adjacent walls so that to form a corridor between common lateral sides and electrical equipment. ^ EFFECT: expanded performances of installation. |
