What is PVC wire?

Pvc电线其实就是指包裹芯材最外层的材料是用聚氯乙烯材料做成的，从某种意义上来说，也是绝缘电线。那么，pvc线缆是怎么发展起来的呢？

Pvc wire actually means that the outermost layer of the core material is made of PVC material. In a sense, it is also an insulated wire. So, how did PVC cable develop?

由于pvc材料物理性能优越、阻燃性好，逐渐被应用得越来越广泛，其中作为电线绝缘体还要从从20世纪30、40年代说起。也正是由于pvc材料、工业助剂的生产能力不断提高，让电缆行业有了质的飞跃。

Because of its superior physical properties and good flame retardancy, pvc materials are gradually being used more and more widely, and as wire insulator, it has to start from the 1930s and 1940s. It is also due to the continuous improvement of the production capacity of pvc materials and industrial additives that the cable industry has made a qualitative leap.

从1984年到2000年期间，国内的pvc电缆产量从10万吨到25.4万吨，这主要是得益于电缆行业的市场需求增大和pvc材料等的深度研究和广泛应用。就目前来说，我国有将近5000多家线缆厂，而且每家线缆厂在不同的发展阶段对pvc材料的要求和开发需求也不同。

From 1984 to 2000, the domestic production of PVC cables increased from 100000 tons to 254000 tons, mainly due to the increasing market demand of the cable industry and the in-depth research and extensive application of PVC materials. At present, there are nearly 5000 cable factories in China, and each cable factory has different requirements and development requirements for pvc materials at different stages of development.

总体上来说，pvc材料的发展主要经历了从普通型到阻燃型，再到非铅型、技术型等的转变和发展，在电缆电线行业也发挥了很大的作用。这也是我们现在常能看到各种pvc电线的原因。

In general, the development of PVC materials has mainly experienced the transformation and development from ordinary type to flame-retardant type, then to non-lead type and technical type, and has also played a great role in the cable and wire industry. This is also why we can often see all kinds of PVC wires now.
