Contents

1.1. Work Object and Input

Outdoor lighting networks of the territory of the designed residential building at the address: Moscow, st. Mechanical Engineering 1st, st. 7. is performed based on:

- topographic plan;

- in accordance with the client's assignment and complies with the requirements of the codes, standards and design rules in force on the territory of the Russian Federation

1.2. External lighting mains are operated at 380/220V AC with grounded neutral. Total external illumination power consumption is 0.42kW

1.3. By illumination, the territory of a residential building is divided into the following zones:

- pedestrian alleys and roads - 4 lx;

- internal, service and economic - 2lk;

- sites at waste collectors - 2lk;

- parking lots - 2lk;

- driveways (main) - 4lk;

- walking paths - 1lk;

- playgrounds for mobile games - 10lk

Single and double LED lamps with asymmetric BEGA light distribution (single pole-top luminaire 77,834 and 77,836, double pole-top luminaire 77,839) with mount on the support, as well as LED columns with lighting on one side of BEGA (Unshielded light 77,246)

To obtain the necessary illumination on the territory of playgrounds, the required number of lamps is designed. Power supply of outdoor lighting supports is performed in ground by cable line

1.4. Install LED lamps on non-power supports of NFG-5.0-02 and NFG-4.0-02 type with height of 5 m and 4 m. Supports have embedded foundation element of 3F-16/4/K140-1,2-b and 3F-16/4/K140-1,0-b type with underground part with depth of 1,2m and 1m, respectively, and flange connection. Embedded element is installed in the railway foundation

LED columns have as part of the structure a fixing unit for installation in soil with an underground part with a depth of 0.3m

1.5. Install external lighting supports at a distance of not less than 0.3m from the front face of the bead stone, the distance between the supports is not more than 30m. At the intersections and junctions of streets and roads, it is advisable to install supports no closer than 1.5 m from the beginning of the rounding, without violating the unified system of the line of installed supports NO

1.6. Control of external lighting is performed locally from the external lighting panel (DCB)

The design provides for the activation of lighting in automatic mode from astronomical time relay in the following modes:

- astronomical sunset and sunrise;

- dusk/dawn;

- adjustment (individual correction of the program of actuations and disconnections by the user: angular or temporary);

- time (designation of "hard" time on and off regardless of the astronomical program of sunrise and sunset)

It is also provided to switch on lighting in manual mode on the front panel of the shield

Install the RBW board in the transformer substation (TP)

1.7. The main design decisions are made in accordance with the current standard projects, the design assignment and agreed with all interested organizations

2.1. Make the supply network of external lighting from TT to the nearest designed ND support by cable, laying it at a depth of 0.7 m from the ground planning elevation, as per PUE standards

Cable wiring inside supports must be performed by 3x2PVA wire,

2.2. Section calculation is performed according to the maximum permissible voltage loss with check for permissible current density and for disconnection at phase wire closure at zero at the most remote point of the network (PUE norms, chaps. 1.3 and 2.4)

Received sections correspond to selected currents of protection devices. Condition 3Iu < Ik.z is met

2.3. Cable sections are selected on the basis of PUE standards, chap. 1.3 according to heating conditions with long-term design current, according to the installed power, permissible current density, voltage loss and disconnection when the phase wire is closed at zero at the most remote point of the network

Cables throughout have one section. Enter the cable into supports of NFG type by "go-around" method through embedded element of foundation, into LED columns - through attachment unit

Set of SV15 + SVV1.06 terminals with melting insert for 6A current to be located inside the panel in the above-ground part of the NFG type support and inside the column

3.1. The design of the street lighting network was carried out in accordance with the "Uniform technical guidelines for the selection and use of electric power cables

lei "and PUE norms, chap. 2.

3.2. The designed cable route is laid at a depth of 0.7 m from the finally planned ground elevation and at a depth of 1 m under the road and the roadway of the yard

3.3. Before laying cables, it is necessary to make a layer of sand on the bottom of the trench with a thickness of at least 100mm. On top of the laid cable, fill with a layer of shallow land that does not contain stones, construction debris and slag with a thickness of at least 100mm. Protection against mechanical damage throughout the cable shall be performed using a corrugated LPA pipe with a diameter of 125mm manufactured by DCS with high annular rigidity

3.4. The smallest bend radius of the cable on the route shall be in accordance with the permitted standards

3.5. Cables are laid with a margin in length (snake) sufficient to compensate for possible soil displacements and cable temperature deformations (Ku = 1.1)

3.6. When crossing existing pipelines, the designed cables shall be laid above them with soil separation of not less than 0.5 m in accordance with typical drawings

When crossing communication, drainage and storm sewer cables, the designed cables shall be laid under them with 0.5m soil layer separation in accordance with typical drawings

3.7. In areas coinciding with the designed cable routes 0.4kV, the designed external lighting cables shall be laid in one trench with them

3.8. Route shall be divided according to the current engineering topographic layout in scale 1:

4.1. Noise and protective grounding are provided as the main protection against electric shock. Ground and protective grounding shall be performed in accordance with the requirements of SP 76.13330.2016, PUE items 1.7.131, 1.7.139, 1.7.142 and Chapter 3.6. Zero wire must be grounded in the RCW board and repeated on each support

4.2. The design provides for automatic power outage in case of short circuits in the designed cable line (CL). With single-phase short circuits at the most distant point of the protected CL, the short circuit current according to the time-current characteristic of the fusible insert (20A) allows you to disconnect the damaged line for a time less than 0.04s

A zero wire connection shall be made by a wire jumper to be connected to the zero wire by a special coupling bolt clamp

The grounding element of the steel support is its underground part - embedded element of the foundation. Ground conductor design resistance is 30 ohms

4.3. Construction and installation works shall be performed by a specialized organization with strict observance of the "Rules on Labor Protection during Operation of Electrical Installations" (POTEE) in the presence and technical supervision of a representative of the operating organization

4.4. The main design decisions are made in accordance with the current standard projects, the design assignment and agreed with all interested organizations

5.1. The following technical solutions are provided for economical consumption of electric energy:

- application of photorelle for lighting control;

- use of efficient light sources - LED lights

6.1. When developing the project, the requirements of the "Legislation on Nature Protection" and "Fundamentals of Land Legislation" are taken into account

6.2. To protect land, the route is chosen in such a way as to prevent, if possible, territorial dislocation of land, without violating the inter-economic and intra-economic ties of land users

6.3. In accordance with the "Land Code of the Russian Federation," enterprises and organizations are obliged to bring occupied land and land plots into a state suitable for further use after completion of work at their own expense

7.1. After completion of construction, construction debris should be removed on the territory of the facility, unnecessary excavations, embankments should be eliminated, planning work should be carried out and improvement work should be carried out.
