Problems solved by technology

[0002] my country is rich in open-pit coal mine resources, and large-scale open-pit mines are mainly concentrated in Xinjiang, Inner Mongolia, Liaoning, and Shanxi. These areas have complex climate changes, large temperature differences between day and night, and extremely low outdoor temperatures in winter. Ordinary mine communication cables must be buried underground to ensure cable protection. The sleeve does not crack in winter, and the construction is relatively complicated; at present, there is no mining communication cable specially designed for the complex working environment of open-pit mines with low temperature resistance, weather resistance, and moisture resistance.

Embodiment Construction

[0019] The following are preferred embodiments of the present invention, and the present invention can be implemented by any method according to the content described in the description.

[0020] Describe in detail below in conjunction with accompanying drawing:

[0021] See attached figure 1 , the mine communication cable includes: the conductor (1) is extruded and covered with an insulating layer (2) to form an insulated core, and two insulated cores are twisted to form a single cable core, and a plurality of cores are stranded to form a cable core , set the isolation layer (3), drain wire (4), copper-polyethylene bonded sheath (5), refractory layer (6), interlocking armor layer (7), outer sheath in sequence outside the cable core (8).

[0022] Conductor (1) and drain wire (4) are made of single-strand tinned copper wire; insulating layer (2) is made of extruded polyethylene; isolation layer (3) is made of high temperature resistant polyester tape; copper- The polyethylen...

Abstract

The invention provides a mining communication cable. According to the mining communication cable, extruded insulation layers outside a conductor form insulated wire cores, every two insulated wire cores are hinged oppositely to form a single cable core, an electric cable core is formed by hinging multiple cable cores, and an isolating layer, a drainage wire, a copper-polyethylene bonding protective layer, a fire resistant layer, an interlocking armor layer and an outer protective sleeve are arranged outside the electric cable core in sequence. The mining communication cable has the properties of resisting electromagnetic wave interference and being tensile, capable of bearing pressure, dampproof, resistant to fire, resistant to low temperature and resistant to weather, and is especially suitable for communication transmission in various strip mines.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a mine communication cable. Background technique [0002] my country is rich in open-pit coal mine resources, and large-scale open-pit mines are mainly concentrated in Xinjiang, Inner Mongolia, Liaoning, and Shanxi. These areas have complex climate changes, large temperature differences between day and night, and extremely low outdoor temperatures in winter. Ordinary mine communication cables must be buried underground to ensure cable protection. The sheath does not crack in winter, and the construction is relatively complicated; at present, there is no mining communication cable specially designed for the complex working environment of open-pit mines with low temperature resistance, weather resistance, and moisture resistance. Contents of the invention [0003] The purpose of this invention is to design and produce a new type of cable structure, which can meet the ch...
