Background technology
Control cables can directly be transferred to various power consumption equipment utensils to electric energy from the distributor point of electric power system, has the functions such as measurement, control and signal transmission, is mainly used in industrial and mining enterprises, energy traffic department.On extraordinary motor-car, because of the characteristics of travelling of extraordinary motor-car, make its requirement to control cables also higher, how control cables in prior art is improved, the low cigarette of preparation, Halogen, the superior extraordinary motor-car control cables of fire resistance, become this area technical problem urgently to be resolved hurrily.
Summary of the invention
The present invention proposes the extraordinary motor-car control cables of a kind of low-smoke zero-halogen fire-resistant type, this control cables hangs down cigarette, Halogen, and fire resistance is good, long service life.
The extraordinary motor-car control cables of a kind of low-smoke zero-halogen fire-resistant type, comprise sheath, the screen coated by sheath, be contained in many groups of combination cores in screen, described combination core is by many stranded the forming of core, described core comprises conductor, is coated on the outer flame retardant coating of conductor, is coated on the outer insulating barrier of flame retardant coating, conductor adopts many stranded the forming of single metal wire, crosslinked, the low cigarette of restrictive coating and/or insulating barrier employing, bittern-free flame-proof material are made, and flame retardant coating adopts the preparation of mica tape material.
Preferably, the screen centre position arranges filled core, and filled core adopts Halogen, fire proofing to make.
Preferably, many cores adopt the pair twist structure mutually stranded.
Preferably, the twisting pitch of described many cores is not more than 16 times of stranded external diameter.
Preferably, 6 groups of combination cores are arranged in described screen.
Preferably, screen consists of the braiding structure of tinned copper wire.
Preferably, conductor twists by five class tinned copper wires the flexible conductor formed with one heart.
The present invention proposes the extraordinary motor-car control cables of a kind of low-smoke zero-halogen fire-resistant type, wherein, filled core, insulating barrier and restrictive coating adopt the preparation of crosslinking type low-smoke halogen-free flame-retardant material, the low cigarette of the control cables of preparation, Halogen, fire resistance is good, and the pernicious gas burst size is little, and radiation resistance is more superior, ageing-resistant performance is good, long service life; Conductor is outer around flame retardant coating, can protect within a certain period of time cable conductor not to be subject to the high ambient temperatures environmental impact, even in the situation that other insulation, protective material all damage, extraordinary motor-car still can rely on the flame-resistant insulation safe operation within a certain period of time of flame retardant coating; Adopt many group combination core pair twist structures and woven shield, anti-electromagnetic interference capability is strong; Conductor adopts five class tinned copper wires to twist with one heart the flexible conductor of composition, and flexibility is good, and rounding property is good, and signal attenuation is low.The fire resistance of this control cables is good, low cigarette, Halogen during burning, and long service life, be applicable to the EMU project fully, and can be widely used in subway, city rail vehicle market, can arrange by open-wire line, but also concealed wire arranged.
The accompanying drawing explanation
Fig. 1 is the extraordinary motor-car control cables cross-sectional view of a kind of low-smoke zero-halogen fire-resistant type that the present invention proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the extraordinary motor-car control cables cross-sectional view of a kind of low-smoke zero-halogen fire-resistant type that the present invention proposes.
With reference to Fig. 1, the extraordinary motor-car control cables of a kind of low-smoke zero-halogen fire-resistant type that the present invention proposes, accompany flame retardant coating 5 between conductor 1 and insulating barrier 2, form core by conductor 1, flame retardant coating 5 and insulating barrier 2, two cores form one group of combination core 7,6 groups of combination cores 7 adopt the mutual line of line structure are incorporated in to filled core of Wen He center interpolation 6 formation cable cores, and twisting pitch is not more than 16 times of stranded external diameter.Conductor 1 twists with one heart flexible conductor by the five class tinned copper wires that meet standard and forms, and this conductor flexibility is good, adopts and restraints with one heart the structure that tangles, and rounding property is good, and signal attenuation is low, and the terminal during constructability wiring is installed; Filled core 6 adopts the preparation of crosslinking type low-smoke halogen-free flame-retardant material with insulating barrier 2, low cigarette, Halogen, fire-retardant; Flame retardant coating 5 adopts the preparation of mica tape material, even in the flame combustion situation, this type of cable also can rely on flame retardant coating 5 to keep within a certain period of time safe operation, for withdrawing of personal security provides effective time; It is stranded to the line structure that 6 groups of combination cores adopt, and can resist a part of external electromagnetic wave interference, reduces self signal and externally disturb.
Accompany screen 3 between cable core and sheath 4, by filled core 6,6 groups of combinations core 7, screen 3 and the common composition control cables of sheath 4, wherein, screen 3 adopts the tinned copper wire programming structure, the control cables of preparation has superior anti-electromagnetic interference performance, and sheath 4 adopts the crosslinking type low-smoke halogen-free flame-retardant material, low cigarette, Halogen, fire-retardant.
