How much different junction solar street lamps Qian Gou high lamp production standards
We usually will be 15 at the time of installation - More than 25 m steel column type light pole and high-power modular fixtures are composed of new type of lighting is called high lamp, it is made up of lamp holder, internal electric lamps and lanterns, rod body and basic parts, now use the rod body is commonly cylindrical dependences of
we usually will be 15 at the time of installation - 25 m steel column type light pole and high-power modular fixtures are composed of new type of lighting is called high lamp, it is made up of lamp holder, internal electric lamps and lanterns, rod body and basic parts, now use the rod body is commonly cylindrical structure, with steel plate, height can reach 15 & ndash; 40 meters. The following follow high lamp manufacturers look at together.
1, electric door has reasonable operating space, light, door has the electrical installation accessories, door and the gap between rod should be less than 1 mm, good waterproof performance, have a special fastening system, good anti-theft performance, the fixed bolt adopts the general authoritarian tools to open it.
2
the rod body, welding process should be without any crack, the welding, continuous pores, bite edge, weld smooth level off, without the concavo-convex fluctuation, without any welding defects, shall provide the weld inspection reports, welding according to the standard, safety standards in line with the national standard.
3, hot-dip galvanized process should be used in hot dip acid put rotten deal with internal and external surface, thickness & ge; 75 um, qualified technology to make the design service life shall be not less than 30 years, the galvanized surface should be smooth and beautiful, color, maul test after peeling, flaking.
4, plastic spraying process coating should be adopted for outdoor pure polyester molding powder, color is white, plastic layer of stable quality, non-deformation, do not fall off. Attached lights as what force is strong, strong solar uv resistance, resistance to ultraviolet ray, make should key Salt Lake City and region. Design service life of less than 30 years, thickness & ge; 80um。
and coating film thickness is not less than 40 um protection requirements, strong adhesion, blade scratch is not peeling, don't fall off, the surface level off is smooth, colour and lustre are basically identical.
5, verticality test
light pole stand straight, after using theodolite to light pole make inspection between the horizontal and vertical degree, vertical degree should be less than or equal to three over one thousand.
6, rod body impressions
high lamp shape and size requirements, overall beautiful generous, rod body surface is smooth, colour and lustre is uniform, smooth level off, the galvanized layer coating layer adhesion force without peeling off.
7, light pole internal threading cable channel, easy to thread, not pointed convex edges, burrs, tusk and similar situation, to avoid damage to the cable.
