PVC junction box is often used to protect wires from aging and corrosion by the external environment.Today Xiaobian is simple to introduce to you the purchase of PVC junction box should pay attention to what problems.
The most important thing to choose what kind of PVC junction box is to look at the choice of raw materials. The PVC wire box is divided into new materials and recycled materials, which are two different production methods.First use of new materials made of PVC trough the appearance of the products is relatively smooth, the touch does not produce rough feeling, and the play of this product is pure white and not mixed with other impurities, and the toughness of this product is very strong, at the same time, the price will be better than other materials will be relatively higher, the decision is mainly the cost of raw materials.Manufacturers in the new and old material is some material doped with some other filling material, but this kind of filling material too much will affect the quality and performance of a field, make the products become fragile, easy to crack, especially in winter, when the product is almost can't use, but also affect the aesthetic of the product, so this is not a durable products, there are a lot of potential safety problems.
Relative to the good PVC box, some inferior products, not only feel more bad, cannot achieve effective size and thickness, and in the process of using will inevitably cause the use of the connection is not working, don't match, and other bad phenomenon, are caused by the bad products, so, when buying right, choose good, choose correctly is the key, still have even if,In a tube head, parallelism is sure to do, like some bad products here do not too good, and then thread small port, or weak, the plug port is the port and check it again whether straight, then, is when choosing PVC wire tube to use, and other equipment in accordance with the match must be use.
