Laying wires on insulating supports

Laying wires on insulating supports(Rollers and prisons)In industrial facilities, and agricultural premises wiring on wards are primarily used for general lighting lines that are laid along and across the building farms. In non-production areas are open wiring on rollers and isolates-tures used in basements, showers and in attics. Hooks with insulators on-kriplyuyut only in the main building basis, and rollers for wires re-rhizomes to 4 mm2 including possible fix for plaster or derev'ya-plating them homes. The corners of accommodation spots and isolators installed on on-state from the ceiling or adjacent walls, a flat polutora - twice height roller or insulator. At the same distance from the wall passes through the base end rollers and insulators .. With all the media mount isolators should be installed yubkamy down to their not going to dust and moisture.

Fastening of insulators to the hooks, anchors, floor anchors and pins made by a tow (tow), tow or hemp, are impregnated with linseed oil with grated red lead and pouring gray or putty from Portland. Recently, for the reinforcement pin insulators widespread ode-rzhaly polyethylene caps. Before the nozzle on a hook or pin-s polyethylene caps dipped in heated to 80-90 ° C water for 5-7 minutes. Heated kovpa Chok-imposed on a hook or pin with light wooden hammer blows, to which then manually wind the insulator until it stops.Construction of insulated wire on the wards on a prepared track concluded with a number of assembly operations carried out sequentially:harvesting ends of the wires, pads and their attachment to the insulators in the execution of branches and connections. Farewell section 10 mm2 pull by hand, spend more sections - pulley blocks (blocks of freight). At intermediate wards wires put on a neck or heads; corner - only a neck, at the end if the line ends without the introduction of machines or devices, instead of binding caps assumed device.
