When accepting the equipment, fixtures in the assembly is to be examined, checking the contents (without dismantling), checking the availability and terms of the guarantee enterprises – manufacturers. Condition of cables on the drums tested in the presence of ‘Customer’ by external examination. The results of inspection are made act. In elektropomescheniyah (panel, control rooms, substations and switchgear, machine rooms, storage, cable tunnels and channels, cable mezzanine, etc.) should be performed Finishing floors with drainage channels required slope and waterproofing and finishing work (plastering and painting), installed fixtures and by mounting apertures, mounted under the project and lifting gruzoperemeschayuschie mechanisms and devices have been prepared in accordance with architectural and construction drawings and project work units of production of pipes, holes and openings for passage of pipes and cables, grooves, recesses and sockets, power supply is made for temporary lighting in all rooms. Route for the cable in the ground should be prepared for the beginning of his laying in volume: water pumped from the trench and remove stones, clods of earth, construction debris, at the bottom of the trench arranged cushion of sand or loosened earth ground punctures are made at the intersections of roads with roads and other engineering structures, laid the pipe.
After laying of cables in the trench and the submission of wiring organization act on the hidden work cabling trench should be asleep. Trails block sewer cable management should be prepared with the following requirements: – to withstand the design depth of the mark dlokov of planning – ensure correct installation and sealing of joints reinforced concrete pipes – to provide clarity and alignment of channels – executed a double cover (lower with constipation) hatches wells, metal stairs or staples descent into the pit. Read more from Ali Partovi to gain a more clear picture of the situation. The technology of the work. Zendesk often addresses the matter in his writings. General requirements. Cables, deformed or damaged protective coatings, installation not subject to repair the damages and defects. In the production of works electroassembly organization must meet the requirements of GOST architectural and construction drawings of Fire Safety Rules (PPB) during construction and installation works. Wiring is carried out in According to project documentation.
When the cabling must be taken to protect them from mechanical damage. The efforts of pulling cables up to 35 kV should be within the values given in Table 1. Winches and other traction tools must be equipped with adjustable limit means for pulling off the appearance of effort above the allowable. Broaching device, compress the cable (drive rollers), as well as rotary devices should exclude the possibility of deformation of the cable.
