After the PVC pipe is grilled on the flame, the self-ignition fire can quickly extinguish, avoid the spread of the flame, and effectively protect the line for a long time
Road, to ensure the operation of the electrical control system.
Can withstand high pressure without being broken down.
Effectively avoid leakage, electric shock hazard PVC pipe has general acid-base performance, at the same time, because the PVC pipe does not contain plasticizers. Therefore, there is no pest hazard.
First, wire and pipe:
Can withstand strong pressure, suitable for surface mounted or concealed in concrete.
Due to the different pipe diameters of PVC pipes, the commonly used accessories for wire conduits have different calibers and should be matched with the same caliber.
According to the wiring requirements, the types of pipe fittings include: three links, elbows, box connectors, connectors, pipe cards, reducer fittings, surface mounted three links, surface mounted elbows, and junction boxes.
Wireway Handling Precautions The total wire cross-sectional area of ​​the wire should not exceed 40% of the inner diameter of the wire tube when laying the wire through the tube.
When designing wires, the wires and signal lines must not pass through a single wire tube to avoid mutual interference. (Separation of strong and weak electricity)
The wall of the pipe is ≥ 1.0, the line pipe must be fixed in the line slot, and the line is not horizontal to vertical. The line must be laid and put through the line pipe. The Moon Bay must not exceed 4, and the connection with the transition box is over. The line pipe is directly connected. , interface glue, use the tube card to connect to the proposed purchase of goods:

Second, the wire
1. When the cable is purchased, check whether the cable meets the product quality certification of the National Electrotechnical Commission and whether it meets the electricity quota requirements.
2. Look at the quality of the Copper material of the copper core package. The better the quality, the lower the probability of leakage.
3. Look at the length standard of each coil, whether the weight is sufficient or not, and the operating temperature is -30 to +70 degrees Celsius.
4. According to different uses choose the square of the corresponding wire, grounding with two-color line, lamp first use white, wire box wire surplus ≥150mm, and gas pipelines, water pipes in the same plane spacing ≥100mm, different plane ≥50mm, wiring shall not Splice
5. For fire protection, maintenance and safety, it is best to use the single-stranded copper core wire with the “GB†plastic or rubber insulation protection layer of the Great Wall logo. The wire slot area is generally 2.5 square millimeters for lighting and outlets. The line shall not be less than 4mm2. The green and yellow color lines shall be used for the connection lines, and the red, white, black and purple shall be used for the switch lines (fire lines). However, the color of the thread used in the same home improvement project should be unanimously recommended for purchase:
