What are the preparations for garden lights before construction

First of all, before the construction of garden lights, check the materials again to see if there are any problems. First: Material requirements: The equipment, equipment and materials used should comply with the current national technical standards, and should have product quality certificates and equipment. Should have a brand name. Second: the garden lamp itself: 1. The accessories of the garden lamp should be complete, without mechanical damage, deformation, peeling paint, cracked lampshade and other phenomena. 2. The cross section of the lamp holder wire should not be less than: copper wire - 1.mm2; aluminum wire - 2.5mm2. Third, pin insulators: 1. The porcelain parts and iron parts should be closely combined, and the iron parts should be well galvanized. 2. The enamel is smooth and free of defects such as cracks, lack of glaze, spots, burn marks, air bubbles or enamel burnt. 3. It is strictly forbidden to use insulators poured with sulfur. Fourth, insulated wires: 1. There should be no defects such as twisting, dead bends, fractures and damage to the insulating layer. 2. The cross section of the down conductor should not be less than: copper wire - 1.5mm2; aluminum wire - 2.5mm2; the rated voltage should not be lower than 500V. Fifth, the lamp holder and hoop of the garden lamp: 1. The surface should be smooth and free of defects such as cracks, burrs, burrs, trachoma, air bubbles, etc. 2. It should be hot-dip galvanized. In case of partial peeling of zinc skin, it should be painted with red camphor and paint after rust removal. Sixth, the bolts used for installing garden lights: 1. There should be no cracks, blisters, zinc peeling and corrosion on the surface of the bolts, and the bolts and nuts should be well matched. 2. Various connecting bolts on the metal should have anti-loosening devices, and the anti-loosening devices used should be well galvanized, with suitable elasticity and in compliance with the regulations. In addition, other materials, fuses, insulating binding wires, soft plastic pipes, rubber cloth, black tape, etc. should also be carefully checked. Seventh, the main equipment needed in the construction of garden lights: 1. Pulley, hand hammer, adjustable wrench, nylon rope. 2. Level ruler, tape measure, foot buckle, seat belt, high stool, etc. Eighth, the working conditions of garden lights: 1. The production of the light frame has been completed. 2. The construction of the overhead line has been completed.
