Embodiment Construction

[0017] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0018] see figure 1 As shown, the sheath structure of the flame-retardant cable of the present invention includes an inner sheath 1 and an outer sheath 2 , and the outer sheath 2 is sleeved on the outer surface of the inner sheath 1 .

[0019] In a specific embodiment of the present invention, the outer sheath 2 is slidably sleeved on the outer surface of the inner sheath 1 .

[0020] Preferably, the inner sheath 1 and the outer sheath 2 are selected from a flame-retardant chlorinated polyethylene rubber sheath, a flame-retardant neoprene rubber sheath or a flame-retardant chlorosulfonated polyethylene rubber sheath.

[0021] In a specific embodiment of the present invention, the flame-retardant chlorinated polyethylene rubber sheath adopts a flame-retardant chlorinated polyethylene rubber with an oxygen index above 35.

[0022] In a specif...

Abstract

The invention relates to a jacket structure of a flame-retardant cable, comprising an inner jacket and an outer jacket; wherein, the outer jacket is sleeved on the outer surface of the inner jacket; the jacket structure has the advantages that the outer jacket can be connected with the outer surface of the inner jacket in a sliding manner, the outer jacket and the inner jacket are flame-retardant chlorinated polyethylene rubber jacket, flame-retardant chloroprene rubber jacket or flame-retardant chlorosulfonated polyethylene rubber jacket, and the flame-retardant chlorinated polyethylene rubber jacket adopts the flame-retardant chlorinated polyethylene rubber jacket with a oxygen index more than 35; the jacket structure of the flame-retardant cable has ingenious design and simple structure, effectively prevents that when using cables, too many mechanical damages are generated on cables so that cables are damaged completely, avoids the frequent happening of underground accidents and is applicable to the jacket structure of mine cables.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to the technical field of flame-retardant cables, in particular to a sheath structure of flame-retardant cables. Background technique [0002] Flame-retardant cables for coal mines refer to wire and cable products for ground equipment and underground equipment dedicated to the coal mining industry. The environmental conditions of cables used in coal mines are very complicated, the working conditions are very harsh, and the area where gas and coal dust gather is very dangerous, which is easy to cause explosion, causing serious personal casualties and property losses. Therefore, higher requirements are put forward for the safety characteristics of cables used in coal mines. [0003] Gas exists in some coal mines, which is easy to burn and explode. It is required that the cables are not easy to burn. Moreover, the cables used in coal mines often move during work, so the sheath is requ...
