11.1. Administrative building and fire station Electric lighting Distribution panels are made of individual manufacture and mounted design with a disconnecting device at the input and group single-phase and three-phase automatic machines with a 3L+N+PE bus system. For general lighting of the fire truck parking area, suspended lamps with incandescent lamps with a power of 150 watts are used. The number of lighting fixtures in the rooms is indicated on the plan. The group lighting network is carried out by a VVG cable with a cross-section of 3*1.5mm2. The cable is laid in the parking area of the fire truck along the ceiling and walls openly with staples. In the premises of the administrative building, the cable is laid in a corrugated pipe behind the hemmed ceiling and in the walls in fines. Lighting control is performed by switches that are installed locally on the side of the door handle at a distance of 0.25 m from the doorway and at a height of 1 m from the floor. Perform the socket network with a cable section of 3 * 2.5mm2 in a corrugated pipe in fines. External power supply The power supply of the administrative building and the fire truck parking building is provided from the projected transformer substation of the KTPN 10/0. 4 kV type with a capacity of 100 kVA, which is connected by the projected 10kV overhead line to the existing 10kV overhead line support No. 26. The 10 kV overhead line is provided on reinforced concrete supports with SV-105-3.5 struts and AC-35 wire. Linear disconnectors RLND 10 and dischargers RVN-10 are installed on supports No. 1 and No. 5. The distance between the projected 10 kV overhead line poles is indicated on the route plan. All poles of the projected 10 kV overhead line must be grounded. Transformer substation adopted KTPN type with 10 kV air input and 0.4 kV cable outputs. 11.2.
