Layout
Specification
1. The outdoor lighting poles shall be powered from the KTPNt-400 kVA outdoor lighting feeder with an AVBbsVv 1 (4x16) mm2 cable, laid in the ground up to the N4 tower. From support N4 to supports N1 and N8, SIP-2 wire 3x35 + 1x54.6 mm2 was laid.
2. The vertical distance from the CIP wires to the surface of the earth and the roadway should be at least 5.0 m.
3. The distance from CIP wires to trees with the largest sag and maximum deviation must be at least 0.3 m.
4. On supports N1, 4, 8, perform grounding devices designed for protection against atmospheric overvoltage, Rз <30 Ohm. On these supports the installation of PC481 clips for connection of voltage control devices and portable grounding is provided.
PROJECT DOCUMENTATION
1. The project was executed in accordance with the requirements of SP31-110-2003, PUE, GOST R50571. 2. Technical solutions adopted in this set of working drawings comply with the requirements of environmental, sanitary and hygienic, fire-fighting and other standards in force in the territory of the Russian Federation, and ensure the safe operation of the facility while observing the measures provided for in the working drawings. 3. The project provides for the installation of outdoor lighting poles with fixtures ZhKU15-250. 4. The outdoor lighting network is made with SIP-2 wire 3x35 + 1x54.6 mm, laid from support N1 to support N8. From KTPNT-400 kVA to support N4, the cable AVBbShv 1 (4x16) mm мм in the trench is laid. Charging of luminaires should be performed with a cable VVGng 1 (3x2.5) mm2. 5. The project provides for the installation of grounding devices on supports N1, 4, 8, designed to protect against atmospheric overvoltages, R <30 Ohms. The grounding device is made of round steel d = 16 mm. 6. Switching on the luminaires is carried out by a signal from a photo relay.
