Description
Technical field
The utility model relates to a kind of field soft abrasion-resistant feed cable, belongs to electric wire field.
Background technology
Along with the develop rapidly of China's aeroamphibious military-related electronics sector, high-performance special electric wire is had higher requirement; The feature of feed cable military in the market can not meet simultaneously: special soft, high-low temperature resistant, hydrolysis, wear-resisting, salt spray resistance, the feature of resistance to mould.
General special power supply cable conductor kind adopts five class conductors (bending radius >=5 times cable size), this conductor structure is softer, but be not suitable for requiring special soft occasion, insulating material adopts PVC, ethylene-propylene rubber, and sheath adopts the materials such as cross-linked polyolefin, conventional polyurethanes, haloflex.The shortcoming temperature resistant grade of PVC material is only-25 ~ 70 DEG C, and anti-wear performance is general.Ethylene-propylene rubber shortcoming is that processing technology is loaded down with trivial details, and tensile strength is poor; Cross-linked polyolefin shortcoming is that material is hard, and do not meet the demand of flexible cable, conventional polyurethanes shortcoming is temperature resistant grade low (-55 DEG C ~ 80 DEG C), and haloflex needs irradiation, and technique is loaded down with trivial details, does not meet Production requirement.
Utility model content
For overcoming above-mentioned deficiency, it is simple that the utility model object is to provide a kind of structure, has softness, high-low temperature resistant concurrently, hydrolysis, wear-resisting, salt spray resistance, resistance to mould and have the advantage of very high tensile strength.
Scheme of the present utility model is as follows: a kind of field soft abrasion-resistant feed cable, cable center is provided with an anti-dilatory cordage, described cordage is all around around six roots of sensation insulated wire cores, described insulated wire cores is made up of the outer wrapping insulation layer of conductor, described conductor forms by multiply tinned wird is stranded, and described insulating barrier is dynamic perduren insulating barrier;
Described cordage and insulated wire cores form cable conductor, the outer wrapped polyurethane belting layer of described cable core, and described polyurethane belting layer weaves tinned copper wire armour outward, the outer wrapped urethane jacket layer of described armour;
Described urethane jacket layer peripheral hardware puts some anti-dilatory polyurethane reinforcements.
Further, conductor adopts the 6th class conductor, the cable size of bending radius >=3 times, strandedly to form by the zinc-plated soft circular copper wire of 4-20 stock is regular.
Further, described armour adopts the high strength thin steel wire of double-deck 0.15mm to carry out braiding armouring, and count is more than or equal to 95%.
Further, described urethane jacket layer also arranges fluorescent belt outward, is convenient to find cable at night.
The utility model has softness, high-low temperature resistant, hydrolysis, wear-resisting, salt spray resistance, resistance to mould and have very high tensile strength.Can work under the maximum conditions of working temperature-55 DEG C ~+105 DEG C; Be adapted to Long-Time Service in coastal wet environment in (>=95%RH), adopt the cable size of bending radius >=3 times, be applicable to being arranged in the electrical control gear of small space, also can reel dragging in the wild for a long time.Meanwhile, also have the following advantages:
1, conductor adopts six class conductors (bending radius >=3 times cable size), high-low temperature resistant (-55 ~ 150 DEG C), this kind of conductor adopts that the zinc-plated soft circular copper wire of multiply is regular strandedly to be formed, and feature is that structure spy is soft, has the feature of less, the more convenient installation of bending radius.
2, insulating barrier adopts dynamic perduren (TPV), and this material has the insulation electrical performance of softness, high-low temperature resistant (-55 ~ 125 DEG C) and excellence.
3, oversheath adopts special high temperature-resistant polyurethane (TPU), and the maximum feature of this material is exactly wear-resisting, and ((-55 ~ 105 DEG C) very high tensile strength (>=20Mpa), hydrolysis, meet the requirement of salt spray resistance, mould to high-low temperature resistant simultaneously.
4, urethane jacket layer peripheral hardware puts some anti-dilatory polyurethane reinforcements, and when cable drags, reinforcement can avoid the wearing and tearing of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
