A: should meet the following requirements: (1) ensuring the safe operation, as much as possible to avoid all kinds of external damage, improve the reliability of electricity supply cable lines; (2) the economic front, from the investment the province of considerations; (3) the construction,7" Digital Photo Frame the cable lines must be easy to spin the path of workers and put into operation after repairs. making cable terminations, the first joint of the insulating material or intermediate what? A: There are insulating plastic, insulation tape, insulating pipes, insulating gloves, insulating resin.
and below the 35kv power cable joints to improve their jacket off at the Field Distribution There are several ways (please list five kinds), and to outline its methods. Answer: (1) Expansion trumpet: in the lead pack to cut the lead pack at the edge of Lever, into a horn shape, its edges should be smooth, round, symmetrical. (2) set aside turnkey insulation: In the lead pack incision to separate the cable core wire between points left some turnkey insulation paper. (3) removal of semi-conductive paper: The semi-conductive paper cut to the bellmouth below. (4) surrounding the stress cone:8" Digital Photo Frame The band and conductive insulating bag into a cone-shaped metal package, artificially shield expanded to improve the electric field distribution. (5) and other potential method: For the dry bag type or cross-linked polyethylene cable head, in each line of the core profile on the surface insulation package a metal band, and connect it together. (6) stress control tube installed: for 35kv and hair under the heat-shrinkable tube cable head, starting with the line core copper shield by the end of the direction of the semiconductor brought to the line core insulation surrounding the two-layer semiconductor band profile, and then the corresponding specification folding stress tube, set at the end of the copper shield, heat-shrinkable shape.
cable bracket processing should meet certain requirements? Answer: (1) The steel shall be straight, no obvious distortion, the next material error should be within 5mm incision should be no curling, hair obstinate; (2) The bracket should be welded solid, no significant Achillea deformation, the cross stays between the deviation of the vertical spacing and design should not be greater than 5mm; (3) metal stent must be treated with preservatives, 10" Digital Photo Frame located in hot and humid, salt, fog and the chemical corrosion areas, shall be designed for a special anti-corrosion treatment.
