Abstract

The invention discloses an explosionproof communication cable. The explosionproof communication cable comprises a conductor, wherein a conductor shielding layer is fixedly connected with an outer surface of the conductor, a high-temperature resistant layer is coated an outer surface of the conductor shielding layer, a fireproof mica tape layer is arranged on an inner wall of the high-temperature resistant layer, a ceramic fireproof fiber tape layer is arranged on an outer surface of the fireproof mica tape layer, a Sb2O3 layer is arranged on an outer surface of the ceramic fireproof fiber tapelayer, a filling layer is coated on an outer surface of the high-temperature resistant layer, and an insulation layer is coated on an outer surface of the filling layer. By application of the conductor, the conductor shielding layer, the high-temperature resistant layer, the fireproof mica tape layer, the ceramic fireproof fiber layer, the Sb2O3 layer, the filling layer, the insulation layer, theexplosionproof layer, a polystyrene layer, a polyethylene terephthalate layer, an outer shielding layer and an outer protection layer in a matching way, the problem of poor explosionproof effect of an existing communication cable is solved, and the practicability of equipment is improved.

Description

technical field [0001] The invention relates to the technical field of communication cables, in particular to an explosion-proof communication cable. Background technique [0002] The cable core is composed of a plurality of mutually insulated wires or conductors, and the external communication line has a sealed sheath, and some are equipped with an outer sheath outside the sheath, and there are various laying methods such as overhead, direct burial, pipeline and underwater. According to the structure, it can be divided into symmetrical, coaxial and integrated cables; according to the function, it can be divided into field and permanent cables (underground and submarine cables). For transmission of telephone, telegraph, data and images, etc., the existing communication cables have poor explosion-proof function, which makes the communication cables easy to burst and cause fire during use, which is inconvenient for users to use. Therefore, we propose a Burst communication cab...
