Use transparent pvc Conduit to make the decoration concealed project transparent! Use transparent PVC threading tube to hide safety hazards!

Next, I will introduce you to the threading common sense of wire threading pipe and the common threading safety.

First, the reason for the wire threading

1, heat dissipation. Because the cross-sectional area of the wire is determined by the load, there is generally a margin in the wiring, but it can also alleviate the heating of the wire caused by special circumstances.

2. Prevent damage to the insulation of the wires. If directly buried in the cement mortar, the silicate may corrode the insulation of the wire, causing the wire insulation to drop and causing a short circuit.

3, the pipe wiring is the basis of the cloth "live line", in order to lay the foundation for future line maintenance, replacement and home intelligence.

4. Prevent fires. In case the short circuit of the electrical appliance causes the insulation of the wire to catch fire, the line pipe can prevent the spread of the flame, because the wire tube is made of flame retardant material and does not burn itself, and is usually called "flame retardant pipe". If the conduit is not used, it is dangerous to have other wires or flammable materials next to the wires.

Second, wire handling notes

1. According to the groove opened at the construction site, the pipe should be arranged on the wall and the top when the pipe is arranged in the water room. Strong and weak wires are not allowed to walk on the floor of the kitchen and bathroom balcony.

2, the layout of the wall pipe should be smooth and vertical, try not to have a bent place. If there is a bend, there should be no obvious creases at the turn. The spacing between strong and weak current must be greater than or equal to 150mm to prevent the cable signal from being unclear. The distance between the gas pipe and the electric pipe should not be less than 150mm.

3. When threading, the sum of the cross-sectional areas of the wires worn in a wire tube must be less than 40% of the cross-section of the pipe. Under normal circumstances, 16mm wires should not exceed 3, and 20mm wires should not exceed 4 wires.

4, strong and weak wires should be laid through the pipe, different types of lines should not be installed in the same line pipe. During the wiring process, the junction box is used at the junction of the conduit, and the wiring cap is used at the wiring. Separate colors when wiring.

5, the height of the switch installed in rows should be consistent, the height difference is not more than 2mm. The spacing between the cassettes is 10 mm, the height of the socket from the ground is generally at least 300 mm, and the position of the switch is generally 1300 mm from the ground.

Third, the common security risks of wire threading

• Wire knotting: the resistance increases and the wire is easily overheated

• Wires are insulated with insulating tape and are prone to corrosion and aging for long-term use.

• Cut corners, use non-branded, inferior wires

• The wire is scratched outside, the copper wire is bare, and it is easy to short-circuit the electric fire.

Subvert the traditional threading pipe and use transparent pvc conduit to make the construction convenient and make the consumption transparent, so that there is no hidden danger in the safety of electricity!
