Abstract

The invention discloses an explosion-proof cable for a high-risk chemical industry, which belongs to the cable field. The explosion-proof cable for the high-risk chemical industry comprises a middle conductor core, and a mica fire-resistant layer, a shielding layer, a first explosion-proof layer, a flame-retardant layer, a second explosion-proof layer and an outer sheath layer coating the cable core from inside to outside sequentially. The explosion-proof cable for the high-risk chemical industry can be used in a high-voltage waterproof anti-electrostatic place, and has the advantages that waterproof, anti-electrostatic field and explosion-proof performance is good; voltage resistance is extremely high; and the operation is reliable.

Description

technical field [0001] The invention belongs to a cable, in particular to an explosion-proof cable used in high-risk chemical industry. Background technique [0002] At present, with the rapid development of industrial automation in my country, explosion-proof cables have been used as power supply equipment in the production process in many fields such as communication, monitoring, detection, alarm and control systems. Among them, the explosion-proof safety power supply is mainly used in the environment of containing mixtures such as coal mines, petroleum, chemicals, textiles and coal mines. Existing explosion-proof cables cannot fully meet the needs of the industry. Contents of the invention [0003] The purpose of the present invention is to provide an explosion-proof cable used in high-risk chemical industry, so as to overcome the defect that the explosion-proof cable in the prior art cannot fully meet the high industry requirements for safety performance. [0004] Th...
