Teflon high and low voltage distribution cabinet installation points (1) device requires cabinet (disk) visual inspection of the body should be no damage and deformation, paint intact. Cabinet (disk) internal inspection: electrical equipment and components, insulation porcelain pieces complete Deng County distribution cabinets, no damage, cracks and other defects. Check before installation distribution box number is consistent with the installation location, according to design drawings check box number, the box loop number. Door grounding should adopt flexible braided copper wire, special terminal. Wiring box should be neat, to meet the design requirements and acceptance (GB50303-2002) requirements. (2) the working conditions of civil distribution box installation site should have whitewashed complete, the doors and windows have been installed good basic conditions. Embedded pipes and embedded parts should be cleaned up; the site with transport conditions, to maintain smooth flow of road. (3) distribution box Location: depending on design requirements on-site and on-site to determine the actual location of the distribution box installation situation, according to the box dimensions were playing the line positioning. (4) basic steel Installation 1) by drawing prefabrication base steel frame and good anti-corrosion treatment, according to the construction drawings of the target position, the prefabricated steel frame on the reserve on the basis of iron, leveling, looking n After basic type of steel, embedded iron parts, gaskets by welding in prison. Top of the foundation should be higher than the final steel smooth surface 10mm. 2) Basic steel Ground: basic steel After installation, you should ground both ends of the base steel weld, weld surface is twice the width of the flat steel and reliable connection and earthing arrangements. And good corrosion protection. Nanyang Teflon power and low voltage cabinet hanging cabinet grounding system installation fabrication and installation (1) Ground network should be strictly in accordance with the "electrical installations engineering construction and acceptance of grounding devices" (GBJ50169-92) performed. (2) The grounding burial depth should meet the design requirements. When not specified, not less than 0.6 meters. Angle iron, steel, copper and other vertical grounding should be laid. In addition to the ground inside and outside the body, grounding lead and ground means of the vertical part of the connecting portion 10 cm range should be embalmed; and to remove rust and welding flux residue thereof. In the ground wire may suffer mechanical damage place, apply pipe or angle iron to protect them. (3) ground through the joints of the building, as fixed by welding, the ground should be made of curved through a period of expansion joints. Make sure (4) between grounding firmly welded between the ground wire or ground wire to the electrical device during lap welding shall, in addition to welding distribution cabinet in contact with both sides, but also by a strip bent on welding a curved (or rectangular-shaped) and steel (or angle) welding. From the steel strip (or angle) should be top 100mm distance. (5) The length of the lap weld shall meet the requirements: flat steel and flat steel lap twice the width of flat steel distribution cabinets Nanyang over and over again, at least three welding; round and round the lap of 6 times the diameter of the round, double-sided welding; round and flat lap 6 times the diameter of the round, double-sided welding; flat steel and steel, flat and angle steel welding, close to the outer angle sides Nanyang distribution cabinet price, or close to the outer most surface of the steel pipe, welding upper and lower sides. (6) grounding device construction is completed, should be ground resistance testing, resistance size to meet the design requirements.
