Abstract
The utility model provides a mining communication cable. The mining communication cable is characterized in that conductors are extruded and wrapped by insulating layers to form insulating wire cores, two insulating wire cores are intertwisted to form a single cable core, a plurality of cable cores are intertwisted to from a cable conductor, and the outside of the cable conductor is sequentially provided with an isolating layer, a conduction wire, a copper-polyethylene bonding sheath layer, a fireproof layer, an interlocking armored layer, and an oversheath. The mining communication cable of the utility model has the characteristics of electromagnetic wave interference resistance, stretching resistance, pressure bearing, moisture protection, fire resistance, low temperature resistance, and weatherability, and is especially suitable for the communication transmission of various strip mines.
Description
Technical field
The utility model belongs to the cable technology field, is 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, the 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.
The utility model content
The purpose of this utility model is design, produces a kind of novel construction of cable, can satisfy 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 solutions of the utility model are as follows:
The utility model provides a kind of communication cable for mine, comprise that the outer extruded insulation layer of conductor consists of insulated wire cores, two thoroughly do away with the edge core consists of single cable core through pair twist, consist of cable conductor after stranded by many cable cores, outside cable conductor, set gradually separator, drainage thread, copper-polyethylene bonding sheath, flame retardant coating, lock armo layer, oversheath.Communication cable for mine of the present utility model 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 usefulness.
Described conductor, drainage thread adopt the 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 the 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 the mica tape stacked package to form, and improves the cable fire-proof performance.
Described lock armo layer adopts the galvanized steel strip lock armo to form, so that cable has good pressure-bearing and tensile characteristics, the earth's surface is laid in the open air, 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 utility model compared with prior art has following advantage:
1, copper-polyethylene bonding sheath conducting surface contacts with drainage thread, with drainage thread ground connection, forms the screen that one deck 100% covers when cable is installed.
2, the lock armo layer adopts the galvanized steel strip lock armo to form, so that cable has good pressure-bearing and tensile characteristics, the earth's surface is laid in the open air, prevents that animal from biting; Traditional sheathed structure generally adopts wire armoring or steel-tape armouring, and can only distribute provides the single defencive function of tension or pressure-bearing, 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 environment for use and the characteristic of cable, so that communication cable for mine can use various complex work environment.
