Installation of the wires hidden in closed channels and void structures

Installation of the wires hidden in closed channels and void structures Feeds for laying wires, in niches, sockets for the installation of shields, electrical appliances perform in wall panels, walls and slabs in the manufacture of building their plants. Channel length between protyahlymy niches and boxes should be no more than 8 m thick protective layer over the channel - 10 mm socket on the concrete panels for direct mounting plug sockets and switches hidden settings must take the form of a truncated cone with a diameter of 70 and 72 mm. Protyahli niche in the wall panel in the ground connection in the form napivtsylindriv perform with a radius of 70 mm or polukonusiv of radii 70 and 80 mm. The depth of the niche in wall panels adjacent apartments should be no more than 50 mm. If the terms of production technology is not recommended to carry out possible holes nekriznymy, then they should be laid with insulating gaskets vynypora unburned or other insulating material

The wires in the channels of paving with no insulation tubes, except sanitary cabins, where laying cables must be performed in polyvinyl chloride tubes hidden. In the bathrooms of residential buildings permitted to lay wire JSPPB hidden under plaster without insulating pipes. Covering the wires do not use machinery or vazhe-Liv, which increase the tightening force (no more than 20 N per 1 mm2 of the total cross section wires). In general, the channel is assumed joint laying wires sent the message to Koh-circles network coverage, including: • Circles of several groups of one type lighting (working or accidental) of the total number of cores of wires in the channel no more than eight, with the exception of group networks apartment houses, where one channel is assumed to lay wires to 12 wires; • lighting circuits voltage to 42 V with circles voltage above 42 V if the output pro-oil pipelines to 42 circles in a separate Shrink Tubing; • Flat wire lines that feed the wires along with working lights stairwells, corridors and other dwellings within the buildings; • the union of zero wires. Joint gasket in one channel interaction reserving circles and circles of working and emergency lighting is prohibited. Lining group networks from floor panel to enter the apartment is in independent channels separately from the group of lines of other apartments. Installation of wirings in industrial channels is recommended to perform them, methods of harvesting all the previous elements of the network centralized but in factories or in the semis electric Meuse on special technological hichnyh lines. Centralized procurement group wirings do: 1. by the process maps, drawn from previous measurements, or typical-washed frequently PPR series of buildings. 2. depending on the adopted technology installation at the facility wiring separate units gathered at the nodal method of installation or sepa-mymy elements connecting switches, sockets and lighting ar-matury in radiation method of installation. Fulfillment of all connections and their insulation covering decorative pla-stmasovymy lids like Kean. All materials and procurement of complex objects-tuyut according to the order and shipping information and bring in special object containers (size 2x1, 7m 2 m). Depending on the volume-syahu works and adopted technologies of electric installation works container ith components stature sets an object in general, section, floor or a stage work. In any case, materials procurement and put in a container in accordance with the technological sequence of their installation on the Saints, yekti. Completion and delivery of containers to simplify the transportation of materials and their consideration of the system, reduce losses, leading to more rational-term labor organization and performance of works by Brigadier contract.
