Abstract
The utility model discloses a super-thin insulation high-temperature resistant, corrosion-resistant, oil-resistant, abrasion-resistant, low smoke halogen-free flame-retardant locomotive vehicle cable, which comprises a conductor and an insulation sleeve layer, wherein the insulation sleeve layer wrapped around the conductor is made of polyether-ether-ketone, the conductor is formed by a plurality of tinned copper wires by means of stranding and compound stranding in the same direction. As dielectric strength of the polyether-ether-ketone reaches 190 k V/ mm which is 10 times of general materials, the volume resistivity of the polyether-ether-ketone reaches 4.9 multiplied by 10 <16> which is about 100 times of the general materials, the mechanical strength of the polyether-ether-ketone reaches 97 M P a which is 10 times of the general materials, then the insulation thickness of the polyether-ether-ketone can be one tenth of the general materials, thereby greatly reducing the external diameter of the cable and being used inside a high-temperature narrow space of a locomotive vehicle.
Description
Technical field:
The utility model relates to cable, and the ultra-thin insulation of a kind of high-performance of more specifically saying so is high temperature resistant, corrosion-resistant, oil resistant, wear-resisting, low-smoke non-halogen flame-retardant rolling stock cable.
Background technology:
China is vast in territory, aboundresources, and railway transportation is one of China's important transportation form, and along with China's economic construction constantly develops, visitor, shipping throughput rate strengthen day by day, and the demand of locomotive car two is also increasing.
The railway transportation of China is by original steam locomotive; diesel locomotive is to the transition of electric locomotive epoch; steam locomotive uses coal to be used as power; diesel locomotive uses diesel oil to be used as power; the electric locomotive vehicle uses electrical actuation power; because electric locomotive uses electrical actuation power; so just need a large amount of electric wires; the space is narrow and small in the electric locomotive; temperature height during operation; mechanical part needs lubricating oil to lubricate; also require low cigarette; Halogen; fire-retardant; so just require the electric locomotive Vehicular system should possess above defencive function; this obviously is difficult to accomplish and the electric locomotive vehicle is when operation; so it is little how we just must consideration make cable itself have a volume; high temperature resistant; oil resistant; wear-resisting; low cigarette; Halogen; performance such as fire-retardant; promptly under certain condition cable to possess volume little; high temperature resistant; oil resistant; wear-resisting; low cigarette; Halogen; performance such as fire-retardant; cable can soak more than 168 hours in 240 ℃ of mineral oil; satisfactory mechanical property; and under naked light, do not burn; cable still can keep normal operation, does not also have a kind of volume with excellent properties little up to now; high temperature resistant; oil resistant; wear-resisting; low cigarette; Halogen; the special-purpose ultra-thin insulated cable of the rolling stock of performance such as fire-retardant.
The utility model content:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of and has that volume is little, high temperature resistant, the ultra-thin insulated cable of locomotive car two of oil resistant, wear-resisting, low cigarette, Halogen, performance such as fire-retardant, to adapt to special operational environment, do not produce harmful material during cable fire.
The utility model technical solution problem adopts following technical scheme:
Ultra-thin insulation is high temperature resistant, corrosion-resistant, oil resistant, wear-resisting, low-smoke non-halogen flame-retardant rolling stock cable, and described cable is by conductor and extrude in the outer field insulating sleeve layer of being made by polyether-ether-ketone of described conductor and constituted.
Described conductor is formed by multiply tinned wird thigh strand and multiple strand, and multiply tinned wird thigh strand is identical with the direction of multiple strand.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The insulating sleeve layer of the utility model cable (double as insulating barrier and restrictive coating) be with fusing point be 343 ℃, heat distortion temperature up to 315 ℃, and polyether-ether-ketone (PEEK) the material made of serviceability temperature up to 260 ℃ continuously; Have good rub resistance and abrasion resistance properties; Splendid acid and alkali resistance corrosive nature is arranged, and be insoluble to all solvents, can resist the erosion of water or high steam, even under the situation that temperature raises, still can keep stable; Do not produce smog and poison gas under fire hazard environment, oxygen index reaches more than 35; Dielectric strength reaches 190kV/mm, is 10 times of general material, and specific insulation reaches 4.9 * 10
16, be about 100 times of general material; Mechanical strength reaches 97Mpa, is 10 times of general material, does not produce harmful material during burning.
Because its dielectric strength reaches 190kV/mm, be 10 times of general material, specific insulation reaches 4.9 * 10
16, be about 100 times of general material; Mechanical strength reaches 97Mpa, is 10 times of general material, so its insulation thickness can be 1/10th of a general material, has so just reduced the external diameter of cable greatly, can use in rolling stock high temperature, the narrow space.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 is conductor, and 2 is the insulating sleeve layer.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment,
Non-limiting examples is as described below:
Embodiment: shown in Figure 1, the conductor 1 of cable meets in the GB/T3956-1997 GB the zinc-plated soft copper conductor of the 5th kind or the 6th kind for performance, adopt multiply fine copper wire thigh strand and multiple strand, and be burst strand and multiple strand version in the same way, insulating sleeve layer 2 adopted fusing point be 343 ℃, heat distortion temperature up to 315 ℃, and continuously serviceability temperature up to 260 ℃ polyether-ether-ketone (PEEK) material made; Have good rub resistance and abrasion resistance properties; Splendid acid and alkali resistance corrosive nature is arranged, and be insoluble to all solvents, can resist the erosion of water or high steam, even under the situation that temperature raises, still can keep stable; Do not produce smog and poison gas under fire hazard environment, oxygen index reaches more than 35; Dielectric strength reaches 190kV/mm, is 10 times of general material, and specific insulation reaches 4.9 * 10
16, be about 100 times of general material; Mechanical strength reaches 97Mpa, is 10 times of general material, does not produce external diameter to the virulent material of human body cable under the constant situation of property retention during burning and has reduced over halfly, is particularly suitable for as the rolling stock private cable.
