Abstract

The invention discloses a C-PVC power cable protection pipe. The C-PVC power cable protection pipe comprises an outer ring, an inner ring, adjusting screw rods and fastening blocks; the C-PVC power cable protection pipe is characterized in that a connecting screw cylinder is arranged in the outer ring; the inner ring is arranged in the outer ring; the outer wall of the inner ring is connected withthe connecting screw cylinder; the inner wall of the inner ring is provided with fixing nuts communicated with the connecting screw cylinder, the adjusting screw rods penetrate into the connecting screw cylinder from the outer ring and penetrate out of the connecting screw cylinder and the fixing nuts, one end of each adjusting screw rod in the inner ring is provided with a clamping ring, each fastening block is provided with an installation ring, and each installation ring is connected with an adjusting screw rod. The distance between the fastening blocks can be adjusted through the adjusting screw rods; therefore, the distance between the fastening blocks can be adjusted according to the power cables of different sizes, the protection pipe can be suitable for power cables of different sizes, the universality of the power cable protection pipe is improved, and the application range of the power cable protection pipe is expanded.

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...
