Skills requirement of solar street light pole
1. Double-armed street lamps are double-headed single-fire lamps.
Motorway lamps are 11.5 meters from the ground and sidewalk lamps are 8.5 meters from the ground.
They are arranged on both sides with a distance of 50 meters.
The light source of the express street light is a 120WLED street light with three light sources,
and the light source of the pedestrian street light is a 80WLED street light with Sanfeng source. Generally,
12m high pole lights are used on the road,
and the cantilever has a single head and double head, 400W high pressure sodium lamp.
2. The light pole material is made of high-quality Q235A steel (the silicon content of the steel is not higher than 0.04%, ),
which is formed by bending.
The wall thickness of the pole does not include the thickness of the galvanized layer.
The main pole of the light pole is a tapered pole with an upper mouth diameter of about 85mm and a lower mouth diameter of about 200mm.
The pick levers are made of steel pipe with a diameter of 60mm, and the pick-up length is 1.6 meters, the sidewalk is 1.2 meters, and the wall thickness is 3mm.
3. The surface of the lamp pole is smooth, and there must be no cracking, missing welding,
continuous air holes, undercuts, or inequality.
The linear error of the center line of the light pole does not exceed 0.02% of the length of the pole,
the surface of the pole body has no unevenness and no traces, and there is no obvious defect in the appearance of the light pole.
4. The welding method of the light pole is automatic sub-arc welding and ultrasonic flaw detection,
which meets the welding GBl1345 level II standard requirements. The lamp pole socket is fixed by using nails and top wires.
5. The light pole adopts hot-dip galvanized anticorrosive treatment,
the zinc layer is not less than 75 microns, the surface is practical and smooth, and the color is basically the same.
After the hammer test, it does not peel, does not peel, and the galvanized life is not less than 20 years.
6. The light pole spraying should use high-quality outdoor pure polyester plastic powder.
The color is to be negotiated, the surface is smooth and smooth, the plastic layer is stable in quality,
does not fade, does not fall off, has strong adhesion, resists strong ultraviolet rays,
and the service life should not be less than 20 years, thickness ≥80um, meet ASTMD339-83 standard.
