temporary construction organization design requires the implementation of the overall layout. 2 site near the high voltage line protection near power lines to have a reliable protective measures protective closely, to meet safety requirements. 3 branch set up distribution box into outlet sleeve and a cross arm to be used; Access to wires neatly, reasonable matching; Prohibited the use of insulation is poor, aging skin, broken wires, to prevent leakage; Should be fixed by insulators, and overhead laying; Line the hallway to have a reliable protection; Direct buried lines, laying depth of not less than 0.6m, leads to the ground from the 2m height to the ground at 0.2m, you must set up protective casing. 4 spot lights hand-held lamp 36V safe voltage should be used; 36V safety at hazardous voltages, particularly in hazardous areas using 12V; Lighting wires should be fixed on the insulators; Insulated rubber sheathed cable for field lights, lighting the use of sheathed wires; Lighting circuits and lighting from the ground not less than the prescribed distance, prohibited the use of electric arc furnace; To prevent the wire insulation is poor, aged, broken skin and leakage, with tungsten heating is strictly prohibited. 5 to set up low-voltage lines are not allowed to use bamboo poles, pole cross arm should be established and insulators; Fine wires can not be mounted on scaffolding or tree branch; Overhead lines required high enough off the ground. 6 electric ...
