Abstract

The utility model discloses a high-temperature resistant, corrosion-resistant, oil-resistant, abrasion-resistant, low smoke halogen-free flame-retardant locomotive vehicle control cable, which comprises conductors and insulation layers extruded on outer surfaces of the conductors. Pluralities of the conductors with the insulation layers are stranded to form a cable core, an isolation layer is wrapped around the outside of the cable core, and a polyolefin sheathe layer and an oil-resistant layer are sequentially extruded on the outer surface of the isolation layer. The oil-resistant layer of the cable is formed by extruding halogen-free phosphate-free flame-retardant polyester-ether elastomer (UM551-V) materials, which has excellent high-temperature resistant (capable of being used continuously when in 200 DEG C) performance, extremely fine abrasion-resistant performance, relatively good ultraviolet light-resistant performance, extraordinary nice oil-resistant performance and halogen-free flame-retardant performance.

Description

High temperature resistant, corrosion-resistant, oil resistant, wear-resisting, low-smoke non-halogen flame-retardant rolling stock control cable

Technical field:

The utility model relates to cable, more specifically say so a kind of high temperature resistant, corrosion-resistant, oil resistant, wear-resisting, low-smoke non-halogen flame-retardant rolling stock control cable.

Background technology:

China is vast in territory, and railway transportation is one of important transportation form of China, and along with China's economic construction constantly develops, passenger transport and freight traffic strengthen day by day, and the demand of rolling stock is also increasing.

The railway transportation of China is by original steam locomotive; diesel locomotive has developed into present electric locomotive; steam locomotive uses coal to be used as power; diesel locomotive uses diesel oil to be used as power; electric locomotive uses electrical actuation power; because electric locomotive uses electrical actuation power; so just need a large amount of power cable and control cable; the space is narrow and small in the electric locomotive; temperature height during operation; there is lubricating oil to ooze out; passenger vehicle also requires low cigarette; Halogen; fire-retardant; so just requiring rolling stock should possess radiating condition will get well; unlubricated oil oozes out during operation; the nontoxic defencive function that waits that human body is not had injury during cable fire; this obviously is difficult to accomplish and rolling stock is when operation; that cable itself is had is high temperature resistant so we just must consideration; corrosion-resistant; oil resistant; wear-resisting; performances such as low-smoke non-halogen flame-retardant; promptly cable is high temperature resistant under certain condition; corrosion-resistant; oil resistant; wear-resisting; performances such as low-smoke non-halogen flame-retardant; cable can be after soaking 70 hours in 100 ℃ 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 excellent high temperature resistance that has up to now; corrosion-resistant; oil resistant; wear-resisting; the rolling stock private cable of performances such as low-smoke non-halogen flame-retardant.

The utility model content:

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of high temperature resistant, corrosion-resistant, oil resistant, wear-resisting, low-smoke non-halogen flame-retardant rolling stock control cable, to adapt to operational environment special on the rolling stock.

The utility model technical solution problem adopts following technical scheme:

High temperature resistant, corrosion-resistant, oil resistant, wear-resisting, low-smoke non-halogen flame-retardant rolling stock control cable, comprise conductor and extrude insulating barrier outside conductor, the stranded formation cable core of many conductors that has insulating barrier is surrounded with separator, is extruded with polyolefin jacket layer and oil resistant layer successively outside separator outside described cable core.

Described oil resistant layer is made by polyester-ether elastomeric material.

The screen that between described separator and described polyolefin jacket layer, has zinc-plated circular copper wire braiding to form.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the conductor of the utility model control cable core adopts thin tinned wird thigh strand of multiply and multiple strand, and is a burst strand version identical with twisting direction again, and pitch is very little, and the conductor flexibility is good.

2, insulating barrier in the utility model and restrictive coating have all adopted low cigarette, Halogen, fire-retardant irradiation polyolefine material, have played fire-retardant effect in use, and burning the time does not have toxic gas and emits.

3, the oil resistant layer of the utility model cable adopts Halogen, without phosphorus, flame retardant polyester-ether elastomer (UM551-V) material to extrude formation, and this material has excellent high temperature resistant (200 ℃ time can use continuously) performance, splendid mar proof, fabulous ultraviolet-resistant performance, splendid oil resistance and halogen-free flameproof performance.

Description of drawings:

Fig. 1 is a structural representation of the present utility model; Fig. 2 is the structural representation of the utility model second embodiment.

Number in the figure: 1 is conductor, and 2 is insulating barrier, and 3 is separator, and 4 is screen, and 5 is the polyolefin jacket layer, and 6 is the oil resistant 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 1: referring to Fig. 1, it shown in the figure non-shield type construction of cable schematic diagram, the cable conductor 1 of present embodiment 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, be extruded with low cigarette outside the conductor 1, Halogen, the insulating barrier 2 that the polyolefine material of fire-retardant irradiation forms, the cable core of the stranded formation control cable of many conductors of tape insulation layer, at the wrapped separator 3 of stranding cable core external application Halogen material, outside separator 3, be extruded with low cigarette, Halogen, the polyolefin jacket layer 5 of fire-retardant irradiation, oil resistant layer 6 is by Halogen, without phosphorus, flame retardant polyester-ether elastomer (UM551-V) material forms, and be extruded in outside the polyolefin jacket layer 5, this non-shield type cable adapts to general occasion to be used.

Embodiment 2: referring to Fig. 2, it shown in the figure shield type construction of cable schematic diagram, present embodiment is with embodiment 1, different is, the screen 4 that outside separator 3, has zinc-plated circular copper wire braiding to form, be extruded with low cigarette, Halogen, fire-retardant irradiation polyolefin jacket layer 5 then outside screen again, this shield type cable is adapted at needing to use under anti-interference, the anlistatig occasion.
