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
The invention belongs to cable technology field, be specifically related to a kind of communication cable for mine.
Background technology
China's open coal mine aboundresources, glory-hole is mainly concentrated Xinjiang, Inner Mongol, Liaoning, Shanxi, that these local climates change is complicated, day and night the temperature difference greatly, winter outdoor temperature extremely low, common communication cable for mine must pass through buried processing, guarantee that cable cover(ing) did not ftracture in winter, construction relative complex; At present, also do not have specially for the complex work environment of opencut and having of designing is low temperature resistant, weather-proof, the communication cable for mine of moisture barrier properties comprises.
Summary of the invention
The object of the invention is design, produce a kind of novel construction of cable, can meet the communication cable for mine of anti-electromagnetic wave interference, tension, pressure-bearing, protection against the tide, fire-resistant, low temperature resistant, weathering characteristics.
For achieving the above object, technical solution of the present invention is as follows:
The invention provides a kind of communication cable for mine, comprise that the outer extruded insulation layer of conductor forms insulated wire cores, two insulated wire cores form single cable core through pair twist, after stranded by many cable cores, form cable conductor, at cable conductor, set gradually separator, drainage thread, copper-polyethylene bonding sheath, flame retardant coating, lock armo layer, oversheath outward.Communication cable for mine of the present invention has anti-electromagnetic wave interference, tension, pressure-bearing, protection against the tide, fire-resistant, low temperature resistant, weathering characteristics, is specially adapted to all kinds of opencuts and does communications use.
Described conductor, drainage thread adopt sub-thread tinned copper wire, increase the anti-corrosive properties of conductor in wet environment.
Described insulating barrier adopts polyethylene to extrude and forms, and has good resistance to low temperature, and chemical stability is good, and the erosion of the most of soda acids of ability is insoluble to common solvent under normal temperature, and water absorption is little, and electrical insulation capability is good.
Described separator adopts wrapped the forming of high temperature resistance polyester band.
Described copper-polyethylene bonding sheath adopts the vertical bag of copper-polyethylene bonding band to form, and plays the effect of protection against the tide, anti-electromagnetic wave.
Described flame retardant coating adopts mica tape stacked package to form, and improves cable fire-proof performance.
Described lock armo layer adopts galvanized steel strip lock armo to form, and makes cable have good pressure-bearing and tensile characteristics, and earth's surface is laid in the wild, prevents that animal from biting.
Described oversheath can adopt low-smoke halogen-free polyolefin, flame-retardant thermoplastic elastomer, flame-proof thermoplastic polyurethane, neoprene, chlorosulfonated polyethylene, any material of haloflex to extrude and form.
The present invention compared with prior art, has following advantage:
1, copper-polyethylene bonding sheath conducting surface contacts with drainage thread, when cable is installed, by drainage thread ground connection, forms the screen that one deck 100% covers.
2, lock armo layer adopts galvanized steel strip lock armo to form, and makes cable have good pressure-bearing and tensile characteristics, and earth's surface is laid in the wild, prevents that animal from biting; Traditional sheathed structure generally adopts wire armoring or steel-tape armouring, can only distribute the single defencive function of tension or pressure-bearing is provided, and adopting lock armo is the Novel armored pattern with above-mentioned two kinds of functions.
3, oversheath can adopt low-smoke halogen-free polyolefin, flame-retardant thermoplastic elastomer, flame-proof thermoplastic polyurethane, neoprene, chlorosulfonated polyethylene, any material of haloflex to extrude and form, can select above-mentioned any sheath material according to the environment for use of cable and characteristic, make communication cable for mine can use various complex work environment.
