Led traffic light installation instructions:
First, the installation sequence explains:
1, single lamp assembly;
2. Placement of light poles;
3, led traffic lights control cable threading;
4. The lamp pole and the crossbar are connected and fixed and assembled;
5, assembled, install the countdown timer, wiring it;
6, signal light direction correction, fixed;
7, ed traffic light pole fixed, fastened;
8, signal pole lifting.
Second, the wiring instructions:
1. Each lamp head is connected to four core wires (ie, three wires and one standby wire). The number of cable cores led by the traffic signal control machine to the pole hand hole is determined by the number of lamp heads configured on the rod, that is, one lamp head uses one core and five cores. Cables, two lamp heads use one 10-core cable, three lamp heads use one 14-core cable, and four lamp heads use two 10-pin cables;
2. In the underground part, the cable is led by the traffic signal machine through the embedded pipe well to the hand hole of the pole. On the ground part, each lamp head leads a 5-core cable to the pole hand hole through the pole hand hole and signal The cables brought by the machine are connected;
3, traffic countdown through the traffic signal lamp wiring, the number of cables is negligible;
4. The power supply and traffic signal are connected by a 3-core cross-section 6mm2 cable.
Third, lamp pole description:
1. The main body of the signal lamp should be gray or silver gray;
2, led traffic light pole protection grounding resistance should be less than 10Î©;
3, the diameter of the embedded threaded pipe should be greater than Î¦50mm, bending angle should be greater than 120 Â°;
4. When installing the traffic light pole, ensure that the pole body is vertical and the slope shall not exceed Â± 0.5%;
5. The installation base of led traffic light poles should adopt ground anchor concrete foundation. The upper end of the anchor bolt is threaded, and the lower end is a bend or other similar pull-out structure with an included angle of less than 60Â°. The anchor bolt should be welded on the lower flange.
SHINE Shuttering Magnets offer an ideal range of applications perfectly suitable for all kinds of formwork construction, both for wood and steel shutterings. All SHINE Shuttering Magnets have strong power in comparison to their weight.
Shuttering Magnet For Precast Formwork are used for building constructions , shuttering magnets is a formwork holder, or cement hold magnet box which made of steel and Block Magnet .The structure of concrete magnet is very trim, every mechanic part are well welded thus the structure is also very stable. Construction workers could adjust the magnetic force through rotate the bold nut,thus they could remove the Magnetic Formwork Systems easily.
The steel shell could focus most of the magnetic force to the bottom while prevent corrosion.The steel surface is plastic sprayed please do not make abrasion on it.
