Breathing air guide composite cable and production method

Abstract

The invention discloses a breathing air guide composite cable. An SYV75-3-41 radio frequency cable, six groups of signal line shielding wire cores and four power line insulating wire cores are comprehensively cabled by taking an air guide pipe as a center to form a cable core; a non-woven fabric belting isolation layer and an aramid yarn braiding enhancement layer are sequentially arranged outsidethe cable core, and finally irradiation chlorosulfonated polyethylene is extruded to serve as an outer sheath. The invention also discloses a production method of the cable. The cable acts on the connection of a long-tube respirator, has the comprehensive performance of integrating breathing air guide, electric power and data communication transmission, eliminates the need of an operator to carrya heavy oxygen bottle, and is suitable for a long-tube respirator air guide connection cable for long-time operation in tunnels, pipelines and deep wells, deep sea exploration and salvage and other oxygen-deficient environments such as dense smoke and dust.

Description

technical field [0001] The invention relates to a breath-conducting integrated cable and a production method thereof, which belong to the field of electric wires and cables. Background technique [0002] Working in an environment with dust or toxic gas for a long time, if you do not use suitable protective products, it will cause damage to the human respiratory system. The damage to lung organs and tissues is usually very serious and irreversible. The finer the dust, the easier it is to enter the end of the bronchi, and the greater the lethality. Respiratory protective equipment is personal protective equipment that prevents the human body from being harmed when oxygen-deficient air and toxic and harmful substances are inhaled into the respiratory organs. In production, daily life and some extreme occasions, the use of respiratory protective equipment to avoid or reduce the harm of toxic and harmful substances in the environment to the human body through the respiratory org...
