Description

technical field

[0001] The invention relates to the technical field of cable protection tubes, in particular to a C-PVC power cable protection tube. Background technique

[0002] C-PVC power cable protection tube is mainly made of C-PVC resin with excellent heat resistance and insulation performance. C-PVC products are currently recognized as green and environmentally friendly products. Its excellent physical and chemical properties are being paid more and more attention by the industry. However, The existing C-PVC power cable protection tubes generally have a simple structure and do not have an adjustment function, so it is impossible to pressurize the built-in storage power cables. Secondly, the power cable protection tubes have low fire performance and are not strong enough to protect the power cables. high. Contents of the invention

[0003] The purpose of the present invention is to overcome the existing problems of the existing C-PVC power cable protection tubes tha...
