Abstract

The utility model discloses a multi-core shielding waterproof cable for rolling stocks. A plurality of insulated wire cores are twisted to form a cable core; each insulated wire core comprises a conductor and an extruded insulating layer outside the conductor; gaps in the cable core are filled with waterproof tapes; the cable core is wrapped with a halogen-free material belting isolation layer and an aluminum-plastic composite tape inner shielding layer successively; a tinned round copper wire weaving shielding layer and an extruded outer sheath are disposed outside the inner shielding layer successively; and a drainage wire is disposed between the inner shielding layer and the weaving shielding layer. The cable is adaptive to different working environments in the rolling stocks, has the performances of high temperature resistance, corrosion resistance, oil resistance, abrasion resistance and interference resistance, is non-toxic during combustion and thus causes no damage to human bodies, has waterproof performance and is applicable to the rolling stocks, thereby being an excellent cable for the rolling stocks.

Description

A kind of used for rolling stock multicore shielding water proof type cable

Technical field:

The utility model relates to a kind of used for rolling stock multicore shielding water proof type cable.

Background technology:

China is vast in territory, and the aboundresources railway transportation is one of China's important transportation form, and along with the continuous development of China's economic construction and high-speed railway, passenger transport and freight traffic strengthen day by day, and the demand of locomotive car two is also increasing.

The railway transportation of China has developed into present electric locomotive and EMUs by original steam locomotive, diesel locomotive; Steam locomotive uses that coal is used as power, diesel locomotive uses that diesel oil is used as power, electric locomotive and EMUs use electrical actuation power; Because electric locomotive and EMUs use electrical actuation power; So just need a large amount of rolling stock cables; On electric locomotive and the EMUs space narrow and small, when operation temperature high, have lubricating oil to ooze out, disturbs big, vibrations greatly; Passenger vehicle also requires low cigarette, Halogen, fire-retardant, waterproof; So just require: on the one hand rolling stock and EMUs should possess radiating condition and will get well, nontoxicly when unlubricated oil oozes out, vibrates little, cable fire when moving human body not had defencive functions such as injury, waterproof; This obviously is difficult to accomplish rolling stock when operation; Performances such as we must consider on the other hand, and to be that cable itself should have high temperature resistant, corrosion-resistant, oil resistant, wear-resisting, anti-interference, low-smoke non-halogen flame-retardant waterproof, promptly performances such as high temperature resistant, corrosion-resistant, the oil resistant of cable, wear-resisting, anti-interference, low-smoke non-halogen flame-retardant, waterproof will be got well under certain condition, and cable can soak back, satisfactory mechanical property and under naked light, not burn in 125 ℃ of mineral oil; Cable still can keep normal operation, does not also have a kind of rolling stock private cable with performances such as excellent high temperature resistance, corrosion-resistant, oil resistant, wear-resisting, anti-interference, low-smoke non-halogen flame-retardant waterproof up to now.

Summary of the invention:

For overcoming the defective of prior art; The purpose of the utility model is to provide a kind of used for rolling stock multicore shielding water proof type cable; Different working environments on the characteristic adaptation rolling stock of this cable; And possess high temperature resistant, corrosion-resistant, oil resistant, performance such as wear-resisting, anti-interference, nontoxic during burning do not have injury, possess waterproof ability and be adapted at using on the rolling stock human body, is a kind of rolling stock private cable of excellence.

The utility model technical solution problem adopts following technical scheme:

A kind of used for rolling stock multicore shielding water proof type cable; Many insulated core is twisted into cable core; Said insulation heart yearn comprises conductor and extrudes in the outer field insulating barrier of said conductor that the cable core gap is filled with waterstop, outside said cable core, is surrounded with Halogen material band separator, aluminium-plastic tape internal shield successively; Outside said internal shield, be provided with zinc-plated circular copper wire woven shield successively, be extruded with oversheath, between said inner shield and woven shield, be provided with a drainage thread.

The design feature of the utility model also is:

Said conductor adopts zinc-plated fine copper wire thigh strand of multiply and multiple strand, and burst strand is with to twist direction again identical.

Said insulating barrier and said oversheath adopt the modification of nylon polyolefin.

Compared with present technology, the beneficial effect of the utility model is embodied in:

1, the utility model cable conductor adopts zinc-plated fine copper wire thigh strand of multiply and multiple strand, and adopts a burst strand version identical with twisting direction again, and pitch is very little, and the conductor flexibility is good.

2, the utility model cable insulation adopts high temperature resistant, the high and low cigarette of insulation resistance, Halogen, fire-retardant radiation modification nylon polyolefin.Played high temperature resistant, good insulation preformance, fire retardation in use, nontoxic during burning do not have the effect of injury to human body, and tensile strength is carried than other materials and changed 30%.

3, fill with waterstop in the utility model cable core gap, play vertical resistance effect; Face outer wrapped inner shield with aluminium-plastic tape aluminium again behind the wrapped separator of cable core external application Halogen material; The aluminium-plastic tape inner shield adds behind the drainage thread with zinc-plated circular copper wire woven shield, improved cable radially water-resisting ability and short circuit current, strengthened the antijamming capability of cable.

4, the oversheath of the utility model cable adopts high temperature resistant, corrosion-resistant, oil resistant, wear-resisting, low-smoke non-halogen flame-retardant modification of nylon polyolefin to extrude sheath.High temperature resistant, corrosion-resistant, oil resistant, wear-resisting, fire retardation have been played in use; The nontoxic effect of human body not being had injury during burning; Cable can soak back, satisfactory mechanical property and under naked light, not burn in 125 ℃ of mineral oil, tensile strength has improved 30% than other materials simultaneously.

Description of drawings:

Fig. 1 is the utility model cross-section of cable structure chart.

Label among the figure: 1 conductor, 2 insulating barriers, 3 waterstops, 4 separators, 5 internal shields, 6 woven shields, 7 oversheaths, 8 drainage threads.
