The utility model is also anti-collision with good flexible characteristic, anti-ageing, corrosion-proof, oil-proof and durable.
Description
Technical field
The utility model relates to a kind of comprehensive transmission trunk cable technical field, relate in particular to colliery transmission trunk cable technical field, apply to the explosion-protection equipment under the various special and adverse circumstances in the modernized colliery, central command computer and adapters such as signal to be provided and to be dispersed in everywhere the electric power between the transducer and to communicate by letter.
Background technology
At present, domestic colliery with trunk cable be with 1 holding wire wrapped after, add in 1 holding wire and the 2 cable source lines 1 holding wire after wrapped wrapped, shielding, aluminum foil shielded, the shielding of electricity matter, the cable signal of this structure is undesirable, the needs that can not adapt to the modern industry development, and sheath uses polyethylene insulation and 70 ℃ of common flame-proof polyvinyl chloride materials, no sheath and serving can not be applicable to occasions such as the vertical shaft in colliery and inclined shaft, and performance is single, insufficiency is especially anti-interference, explosion-proof, the retaining tide, flame-retardant smoke inhibition, transmission characteristic, high-low temperature resistant, anti-aging, aspect of performances such as anti-collision exist obviously not enough.Prosperity day by day along with the coal in China extraction industry, all kinds of colliery construction change to the condition of the degree of depthization, complicated and abominableization, stratification, inflammable, explosive, high humidity, strong electromagnetic and working space level complex phenomena occur and increase day by day, cause under the open well trunk cable to be difficult to adaptive system and equip suffered environment requirement.
Technical scheme
The purpose of this utility model provides a kind of signal stabilization, and function is complete, and performance is good, the novel transmission trunk cable of adaptable colliery.
The technical solution of the utility model is to realize like this, it comprises conductor, holding wire, the cable source line, insulating barrier, the isolation strip, aluminium-plastic tape, woven shield, oversheath, it is characterized in that, it also comprises double-deck fireproof glass strap, inner sheath, the braiding armour, wrapped double-deck fireproof glass strap on the conductor, extrude crosslinked polyetylene insulated layer, constitute signal core and cable source line, by using individual layer PE isolation strip behind two signal core pair twists, the individual layer aluminium-plastic tape is wrapped, its outer wrapped again individual layer PE isolation strip, constitute holding wire, constitute cable core by the wrapped holding wire in double-deck PE isolation strip and two cable source lines.
Be provided with to let out between said individual layer PE isolation strip and the individual layer aluminium-plastic tape and disturb line.
Be provided with the non-hygroscopic filler in the said cable core.
Outside the said double-deck PE isolation strip, wrapped individual layer aluminium-plastic tape, tincopper fuse wire braided armor.
Squeeze PE sheath, zinc-coated wire braiding armouring between said tincopper fuse wire braided armor and the outer jacket.
Said conductor adopts the zinc-plated thin copper wire skein of multiply to form.
Said outer jacket squeezes high flame retardant chlorination sulphur polyethylene irradiation material.
Effect of the present utility model is as follows:
1, conductor braid shielded layer material all adopts tin plating technique, improves the antioxidant capacity of material, keeps its original physical characteristics.
2, conductor adopts the zinc-plated thin copper wire of multiply through twisting the technology bunchy again, form outer jacket and adopt the strong high flame retardant chlorosulfonated polyethylene irradiation material of flexibility, both improved the softness of cable, flexible, stretching makes things convenient for the down-hole to install and safeguard and has strengthened the cryophylactic characteristic of cable again.
3, two signal transmssion lines take pair twist formation line right, reduce line and distance between centers of tracks, thereby reduce distributed capacitance and distributed inductance, improve the explosion-resistance characteristic of cable greatly.
4, the conductor of holding wire and power line all coats double-deck fireproof glass strap outward and extrudes crosslinked polyetylene insulatedly again, makes the conductor maximum temperature reach 150 ℃---and 200 ℃, strengthen the heat resistance and the thermal stability of cable, improve the ability of the continuous duty of cable.
5, whole cable core adopts winding PE band to twine aluminium-plastic tape again, squeeze the outer good high flame retardant chlorosulfonated polyethylene sheath (it is stronger about 40 times than polyvinyl chloride to keep off damp performance) of watertightness that squeezes again of cover in the low density PE again, and the cable core structure compactness increases the performance that cable radially keeps off tide.
6, the cable core of cable adopts and protects in the PE and zinc-coated wire braiding armouring, strengthens the effect of cable external force resistance, more is applicable to the operation area of coal mine shaft or inclined shaft.
7, protective coverings of cable adopts the blue chlorosulfonated polyethylene of high flame retardant, and oxygen index reaches 32-35, and fire resistance is superior, and the chance naked light is nonflammable and do not prolong combustion under the naked light effect, but also has characteristics such as ageing-resistant, corrosion-resistant.
8, aluminium-plastic tape is twined in two holding wire phase-splittings, wrapped and the tinned copper wire braiding double layer screen of total again aluminium-plastic tape, can control interference source like this because inner two power lines of cable core generate an electromagnetic field, also strengthen simultaneously the anti-outer magnetic source interference capability of cable greatly, make cable keep original electrical property and physical property.
The utility model keeps off that strong, the explosion-proof index height of damp performance, strong anti-interference performance, transmission performance are superior, highly effective flame-retardant and do not prolong combustion, that the high-low temperature resistant ability reaches softness characteristics by force is good, also have excellent mechanical property and anti-collision, anti-aging, corrosion-resistant, oil resistant with and long service life.
