which is the best high lamp manufacturers? Today, the side will briefly introduce the shaw high lamp ( 。 jschindo。 com) Usually refers to the steel column and high-power light pole lamp holder of new type of lighting. Its height is 15 40 meters. It is mainly composed of base, inner light electricity, rod body and base parts. The shape of the lamp holder can be based on user requirements, and lighting needs to determine the surrounding environment. High lamp inside the lamp is mainly composed of omni and project-light lamp, light source for lighting radius is 60 meters NG400 high-pressure sodium lamp. Rod body is commonly cylindrical structure, with the steel plate rolling, height is 25 meters. 40 meters is to point to by steel column light pole and a combination of high power lamp holder made of more than 25 meters new lighting device. According to the market demand, shandong light, high lamp manufacturers, the main functional, reasonable structure, stable performance, convenient operation and use. It has been widely used in square, Bridges, ports, docks, train marshalling yard, the airport tarmac and broad road of large area lighting. Light, the light pole mainly divided into two categories: cone and polygon sprayed; ( 1) Conical light pole section roundness error should not exceed 5 microns; 。 ( 2) The side of the polygon pyramid light and the distance between the diagonal deviation less than 1%. ( 3) On the surface of the light pole unipolar distortion error is not more than 7 degrees; 。 Detailed description: high lamp pole pole axis straightness error shall not be greater than 2 times of the pole length; 。 Lighting design should conform to GBJ17 specification for design of steel structure. Under the action of wind pressure of the maximum stress values should be less than the design value of material strength. High lamp light pole of the welding quality shall comply with the requirements of GB/T12469, can not have cracks, slag inclusion, flash, burn through, and impact strength of arc crater needle hole, can not have defects such as fold and interrupt. Stainless steel composite steel welding shall comply with the relevant provisions of the GB/T13148. Light pole shape should not be less than 8 m at a time. When stitching light pole, should add a light pole on casing in joining together, its length is not less than 300 mm, thickness is not less than 80% of the light pole wall thickness. Plug-in lamp post insertion length should be greater than insert position 1 the diameter of the big end. 5 times. Light pole plug in, fit clearance shall not be greater than 3 mm, light pole length should comply with the design requirements. Light pole welding inspection requirements shall be in line with the GB/T11345 evaluation criteria. Lamp door ( Or open) Should be strengthened. To ensure the mechanical properties of not less than the strength of the door is not open.
