How to choose a good PVC wire?

In all aspects of life, we will talk about a lot of wire and cable projects. It can be said that our modern technological life is inseparable from wires and cables. Because it can be seen everywhere that electricity is used in homes, schools, hospitals, roads, power stations, and the whole earth, wherever there seem to be human beings, except for primitive tribes, but it is not excluded. They will also use electricity later.

Therefore, in addition to light bulbs, we all use electricity, and the carriers of electricity are wires and cables. So, let's talk about what kind of wires are used for PVC cables in modern life, and how most of them are distinguished from good and bad.

1) Ignition: check whether it is flame retardant, see if it is extinguished immediately after leaving the fire, and whether there is any residue falling;

2) Burst: directly throw the line pipe on the ground with force, if the line pipe is broken or directly broken into pieces, it also means that the toughness of the line pipe is not enough. Good quality wire and tube, not easy to break.

3) Explosive stepping: Use the root of the foot to directly and forcefully step on it. If the line tube bursts and breaks or is directly broken into pieces, it also means that the toughness of the line tube is not enough. Good quality wire and tube, not easy to break.

4) Instant empty bend: Hold both ends of the line tube with both hands and break it directly. If the line tube is directly broken or broken, it means that the "bending and flattening performance" of the line tube is not high. Good quality conduit, not easy to break or break.

5) Color: Whether it is bright and shiny, it is to check whether the material is mixed with waste and recycled materials.

6) Stroking: Whether the inside of the tube is smooth and the wall of the tube is uniform
