Description

The fluoroplastics control cable

Technical field

The utility model relates to a kind of cable, relates in particular to a kind of fluoroplastics control cable with better fire resistance and resistance to elevated temperatures.

Background technology

The growth continuously and healthily of China's economy, for cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight, reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry allows the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.

In numerous cables, the effect of control cable is that the transmission non electrical quantity is controlled some equipment and instrument of signal controlling with controlling or transmitting, the appearance of control cable has solved problems such as transmission signals is weak, signal interference, distorted signals, and equipment and instrument can run well as indicated; In the past, employed control cable in the industrial sector, owing to lack the shielding of signal to external world or other physical parameters impact, just can not meet the demands if use it for some highly sophisticated devices, a very little interference signal just can make the result mistake occur, make Control Failure, and these cables can not bear mechanical external force; Therefore, screen is used in the control cable, the purpose of shielding is to prevent that the induced signal of cable outside from influencing the energy or the quality of signals of cable transmission, and then the correctness of assurance system responses, at present, domestic being seen electric wire shielding construction mainly contains three kinds, and promptly copper strips puts up that wrapped formula, copper wire are woven, aluminium-plastic tape is put up wrapped formula.

In the modern industry development, energy or quality of signals requirement to cable transmission are more and more higher, therefore also more and more higher to the requirement of shield effectiveness, when the shield effectiveness of cable itself does not reach system requirements, will with cable laying in shielded-plate tube, increase production cost; In addition, some electrical equipment that are used for special control appliance connect with the shielding control cable, at first can be abominable because of environment such as fields of employment, have high temperature resistant, fire-resistant, wear-resisting etc. more multi-functional when requiring cable work, secondly, cable is also wanted at aspects such as flexibility, insulating properties to satisfy instructions for use, but the thermal insulation layer of this type of cable mostly is coiling multi-layer high-temperature band at present, therefore cost an arm and a leg, production cost height, and the wrapped structure of coiling multi-layer high-temperature band are not entities closely, gapped between band and the band, overlapping influenced when manual coiling with the surface quality meeting.

Therefore, be badly in need of a kind of fire resistance, resistance to elevated temperatures is better, has the low control cable of better shielding properties and production cost simultaneously.

The utility model content

The purpose of this utility model is to provide a kind of fire resistance, resistance to elevated temperatures better, has the low control cable of better shielding properties and production cost simultaneously.

For achieving the above object, the technical solution of the utility model is: a kind of fluoroplastics control cable is provided, it comprises some leads, described lead comprises conductor, the insulating barrier of the silicon rubber that described conductor is coated with, described insulating barrier is woven with the braid of heat resistant glass silk braiding outward, described braid is extruded with the inner covering of fluoroplastics outward, described inner covering is woven with internal shield outward, described internal shield is extruded with the outer lining of fluoroplastics outward, described lead is gathered stranded formation cable core, described cable core is surrounded with the lapping layer of heat resistant glass cloth outward, and described lapping layer is extruded with the sheath of fluoroplastics outward, and described sheath is woven with outer shielding layer outward, described outer shielding layer is surrounded with the separator of nonwoven fabrics band outward, and described separator is extruded with the outer jacket of fluoroplastics outward.

Preferably, the utility model fluoroplastics control cable also comprises fire-retardant obturator, and described fire-retardant obturator is filled between each lead of described cable core, and fire-retardant obturator makes cable rounding, Stability Analysis of Structures, be convenient to the stranded moulding of lead, play fire retardation simultaneously.

Preferably, described internal shield is formed by the copper cash braiding, is woven with screen in the lead, strengthens the anti-interference of signals transmission, improves the fail safe and the stability of cable transmission.

Preferably, described outer shielding layer is that tinned copper wire is woven in aluminium-plastic tape and forms outward, tinned copper wire is woven in aluminium-plastic tape and forms double-deck outer shielding layer outward, this outer shielding layer rejection coefficient is little, anti-strong electromagnetic, guarantee the accuracy of electric energy transmitting and control signal, for safety in production provides sound assurance.

Compared with prior art, because the utility model fluoroplastics control cable, it comprises some leads, described lead comprises conductor, the insulating barrier of the silicon rubber that described conductor is coated with, described insulating barrier is woven with the braid of heat resistant glass silk braiding outward, described braid is extruded with the inner covering of fluoroplastics outward, described inner covering is woven with internal shield outward, described internal shield is extruded with the outer lining of fluoroplastics outward, described lead is gathered stranded formation cable core, described cable core is surrounded with the lapping layer of heat resistant glass cloth outward, and described lapping layer is extruded with the sheath of fluoroplastics outward, and described sheath is woven with outer shielding layer outward, described outer shielding layer is surrounded with the separator of nonwoven fabrics band outward, and described separator is extruded with the outer jacket of fluoroplastics outward; Because the lead and the cable core of this fluoroplastics control cable all have screen outward, can shield external interference preferably, improve the fail safe and the stability of cable transmission; Heat resistant glass silk braid and heat resistant glass cloth lapping layer have resistance to elevated temperatures preferably, and the resistance to elevated temperatures of cable is improved greatly; The sheath of fluoroplastics material and outer jacket have fire resistance and resistance to elevated temperatures preferably, and therefore, the utility model fluoroplastics control cable fire resistance, resistance to elevated temperatures are better, and it is low to have better shielding properties and production cost simultaneously.
