Search-for-imaging cable

Abstract

The invention discloses a search-for-imaging cable including a cable wire core, a filling cotton rope, an inner sheath wrapping the wire core and the filling cotton rope, a fiber reinforced compositeplastic strip, a fiber braiding layer and an outer sheath wrapping the fiber reinforced composite plastic strip from inside out in sequence. By the use of the fiber reinforced composite plastic strip,the finished product cable can have higher tenacity, so that problems of a conventional cable of twisting and knotting during use can be solved. Besides, the fiber reinforced composite plastic stripis low in self weight, good in insulation performance and good in environment resistance, so that the environment resistance of the cable can be improved. Also, adaptive adjustment on the structure ofthe search-for-imaging cable can be performed by utilizing the quantity of the fiber reinforced composite plastic strip, so that integral structural stability can be maintained and the adaptability of the search-for-imaging data is enhanced. At the same time, by adopting the TPU as the outer sheath, the cable has characteristics of good wear resistance, good oil resistance and good elasticity andthe like, is suitable for complex occasions including an underground pipe network and the like, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to a wire and cable, in particular to a wire and cable with good toughness and resistance to environment searching and imaging. Background technique [0002] With the continuous expansion of the underground pipe network, in daily maintenance and abnormal handling, it is particularly important to visualize the interior of the pipe network. The requirements for the performance of the cable as the transmission nerve are very high, especially when the cable is facing a complex environment. Environmental resistance and toughness in the face of complex pipe network channels. [0003] Existing cables generally adopt armored structure and PVC sheath. However, the armored structure increases the weight and hardness of the wire, which leads to inconvenient movement, difficult manual work, and is not easy to bend; the PVC sheath has poor environmental resistance, especially in harsh environments such as oil, acid and alkali, and rats. In t...

AI Technical Summary

Problems solved by technology

The armored structure increases the weight and hardness of the wire, which leads to inconvenient movement, difficult manual work, and is not easy to bend; the PVC sheath has poor environmental resistance, especially in harsh environments such as oil, acid and alkali, and rats. In the pipe network, it is easy to crack and age

Therefore, it is difficult for the above-mentioned existing cables to meet the performance requirements of the wire and cable for searching and imaging in complex and harsh environments.
