What are the requirements for terminal high lamp design?

In accordance with the tenderer for the appearance of the shape and structure parameters according to the seismic magnitude 7, fortification was 12th level; Main stem for twelve sprayed, light pole structure and basic structure size calculation. Light pole as the transportation is convenient, high light pole adopts the plug type, every day, splice length should not be less than 1000 mm light pole plug after good fit clearance shall not be greater than 3 mm and a reliable limit device.

light pole foundation design should match light pole, base with concrete structure, based on the left a fixed light pole anchor bolt and the flange plate fixed anchor bolts in the flange; Based embedded within the in and out of the cable threading pipe, threading pipe using hot dip galvanized steel pipe, and mark the foundation reinforcement, concrete strength grade, such as construction drawing, stainless steel manufacturing, reliable and durable easy to operate. All kinds of nut fastening, should add washer and spring washer, tighten the screw with nut should not be less than two pitch. The top set up independent lightning rod,

high lamp manufacturers think around the base earthing body, grounding resistance is not greater than 30 European, grounding electrodes by 2. 5 m long, 50 * 5 galvanized Angle steel, galvanized flat steel the ends of the earth line is 25 * 4. Grounding body with light pole, lamp plate, reliable connection, such as distribution box forming solid conductive path. 【 The above content released by port high lamp factory finishing 】
