A kind of frost-resistant and high-temperature resistant composite cable protection sleeve

Abstract

The invention discloses a frost-resistant and high-temperature-resistant composite cable protection sleeve, which comprises a No. 1 protection sleeve, a No. 2 protection sleeve, a sleeve connection unit and a separation unit. The present invention can solve the following problems in the use of the existing cable protection sleeve: 1. In the existing cable protection sleeve, the cable directly contacts the inner wall of the cable protection sleeve, and the external temperature is directly transmitted to the cable through the cable protection sleeve. On the one hand, it makes its antifreeze and high temperature resistance performance poorer, causing the thermal expansion and contraction of the cable to cause damage to the cable; two, the existing cable protection sleeve joints have poor sealing performance, and are also easy to loosen and bend , resulting in lower reliability of the cable protection sleeve. The present invention can suspend the cable in the cable protection sleeve, avoid direct contact with the protection sleeve, have effective anti-freeze and high temperature resistance, and at the same time ensure that the cable protection sleeve The tightness and reliability of the interconnection.

Description

technical field [0001] The invention relates to the field of protective sleeves, in particular to a protective sleeve for frost-resistant and high-temperature-resistant composite cables. Background technique [0002] The development of modern high technology is inseparable from composite materials, and composite materials play a very important role in the development of modern science and technology. The research depth and application breadth of composite materials and the speed and scale of production development have become one of the important symbols to measure the advanced level of a country's science and technology. Composites are a mixture. It has played a great role in many fields and replaced many traditional materials. The cable protection sleeve produced by this composite material also has various advantages. [0003] However, the existing cable protection sleeve has the following problems in use: 1. In the existing cable protection sleeve, the cable is directly...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a cable protection sleeve of antifreeze and high temperature resistant composite material, which can solve the following problems in the use of the existing cable protection sleeve: 1. The existing cable protection sleeve is directly connected to the cable protection sleeve The inner wall is in contact, and the external temperature is directly transmitted to the cable through the cable protective sleeve. The performance of frost resistance and high temperature resistance is poor, and the thermal expansion and contraction of the cable will cause damage to it; Poor, but also easy to loose and easy to bend, resulting in low reliability of the cable protection sleeve and other problems
