the LED road lamp installation

a. Preparation work in advance in the

disassembly and assembly address selection: remove the address should be the installation around, easy to assemble after delivery. In addition, the installation address covered by rain wear, implantation due to the road bumps or sediment and dirt and damage, scratch and contamination etc.

b。 Street lamp parts assembled

street lamp parts assembled according to the steps to carry out the assembly ( Install pick arm & rarr; Install lighting & rarr; Assembled lamp parts & rarr; Lighting lamps and lanterns of inspection)

c。 Project construction key point

used cranes, specially made buckle lock ( Slide, solid, discharged from pine convenient handling) , rope, lifting point ( Pole high 1/3) Beyond the 4th level wind installation. Use dry forced cement mortar or cold-rolled steel ground leveling, alignment with the vertical ball method, attention after installing bolts at once.

( 7) The cable laying and electric equipment installation

a. The cable laying

1) Cable entry inspection acceptance of work

after the cable entry, be sure to check of the cable to carry out detailed engineering acceptance, inspection, model specifications, rated voltage of cables, length, the mark of certificate of quality, high temperature resistant flame retardant; Its thickness and sampling on the spot inspection cable sheath and the diameter of the ring wire core.

2) Cable laying in advance to prepare

technical advance preparation: scientific research electrical shop drawing attentively, grasp the condition of cable around, to carry out the serial number for each cable, and cable's start-stop parts, control loop number, specifications, etc. ; Gathered on the cable area, drawing model of cable distribution, display information cables in the jumper position; Fusion model of cable distribution, and choose the best cable laying order, decrease as far as possible the status of the cable a job; Workers and machines are prepared ahead of time.

are prepared ahead of time: on the spot check the jumper is installed and brace load condition, jumper and remove dirt; Remove cable laid along the road block, to put cables make very good standard.

3) Cable installation

before laying, cable insulation layer should shake test, 500 v when the grounding resistance value is not less than 2 m & Omega; Before closing the, shake test once again.

edge of cable, cable joint, turning area, should be placed direction, the direction is marked the route number, when number disorderly, should indicate the cable type, specifications and all address; Series cable need to be ordered, direction handwriting is clear, it is not easy to fall down; Giving directions specifications must be consistent, can anti-corrosion materials, hanging wall should be strong.

line pipe laying cable, laying cable makes the cross section of design scheme and standards; Cable laying, cable should be from the top of the tray to find out, should prevent cables in supporting frame and the surface friction drag their feet; Cable is not not clear on the machinery and equipment damage.
