Parking system wiring installation should pay attention to two aspects, one is the choice of line pipe, 2 it is cloth tube technology.Let’s one by one.

the line pipe, parking system choice

1. The choice of line pipe size.Line pipe size is according to the through the conductor is how to choose, if you want to wear less line, line pipe can be chosen, the diameter of the bus is usually wear not greater than 70% of line pipe diameter.
2. The parking lot system line pipe material selection.

parking usually choose PVC line pipe as the main line, because PVC conduit economical and practical, corrosion resistance, suitable for use where not withstand mechanical load.

if the wiring area need to withstand mechanical load or requires fire prevention, prevent electromagnetic wave and high frequency signal interference, if there are any vehicles through the road, you need to use steel pipe wiring, PVC can’t stand the weight.Use of steel tube is important to note that the tube should not be used in corrosive environment.

2, parking system cloth tube

1. Dark buried PVC is divided into indoor dark bury and outdoor dark buried, buried under the protective layer of 30 mm indoors, and PVC pipe outside dark buried depth should be about 100 mm, more than 5 cm at the exit, and in the tube head end bending back to line pipe into the water.
2. The power cord and signal lines to separate wiring, wear in different line pipe, parallel arrangement and requirement, this is to avoid interference.
3. For future maintenance, easy extension, also note the following points.

I) should try to avoid turning line pipe, such as inevitable, then the bending radius should be greater than 90 degrees, and should be as large as possible
ii) at the convenient at the same time, Suggestions on the wire tube wear 12 wire at the same time, in order to facilitate future maintenance
d) indoor wiring conduit or trough:
I) should be horizontal flat vertical, as far as possible avoid cross, points, lines and joint should not be influenced by the role of the external force
2) the inclination of the horizontal or vertical line groove or tube shall not be greater than 3 mm/m.
iii) straight tube wiring for natural straight, every 1.5 meters fixed a pipe clamp, joint, in case of parallel beams should be to keep
