with the continuous development of science and technology, signal light pole, more and more used in our work life, so if the signal light pole there is a problem how to repair? Let monitor rod small make up to introduce for you. Signal light pole lamp light pole when installation should guarantee the vertical rod body, slope shall not exceed + 0. 5%. 9. 2 cantilever, bracket, tie rod and the fixed a

cantilever bar with the support bar can be used more than round or prismatic variable cross-section profiles production, appropriate welding flange fixed cantilever connected to the light pole end, cantilever under the bore into the line and outlet shall be maintained. Tie rod made of round steel, should be used at one end is equipped with adjustable screw of the distance, diameter and length according to cantilever length, etc. Bracket can be used to embrace hoop, hoop seat connected to the light pole is fixed. Rod and light pole, pull rod and bracket, bracket and the bracket can use plywood fixed connection. Installed with a fixed bolt, nut, washer should use hot dip galvanized parts and spring gasket pressure. Threading pipe should use joint casing is fixed, and should have a sufficient strength of the concrete protective layer. When using the rigid plastic pipe, hard plastic tube around the appropriate package has enough strength of concrete protective layer. Each root canal orifice must be strictly deal with burr. Embedment depth of the underground cable threading tube to the top of the distance of the road, not less than 40 cm. Each group of signal should be separate use a cable connected to the signal. Cable should be used on the nominal area of not less than zero. 75 was the copper, plastic insulation, plastic sheath or special rubber insulation, sheath cable. Power cable can have 1 to 4 shares each spare conductor. Aerial cable laying: can't using underground cable laying mode, the overhead cable laying method. Aerial cable overhead clearance shall be not less than 6 m. Aerial cable should be used steel strand cable hoist. Overhead cables in the signal tractor source 2. Should be used under 5 m steel threading pipe, threading pipe should be at the top of the inverted U type backwater bending or install waterproof outlet tube cap. Underground cable laying it is forbidden to have joint. Underground cable threading pipe nominal diameter should be used - 50 Within 100 mm corrosion liner of the hot dip galvanized steel or hard plastic tube, usually steel pipe used for roadway, hard plastic pipe used in the pavement. The same root on both ends of the cable shall have the same identity. Should adopt corresponding core insulation color easy to with light color in order to install and maintain. If the conductor insulation layer with color, the ends of the conductor shall have the same logo per share, appropriate USES digital serial number identification. Underground cable laying, appropriate USES light cable laying underground, each power cable allowance shall be maintained.
