Description
Technical field
The utility model relates to cable industry, is specifically related to the wear-resisting feed cable of the extraordinary soft high-low temperature resistant in a kind of field.
Background technology
Along with the develop rapidly of China's 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: soft, high-low temperature resistant, hydrolysis, wear-resisting, salt spray resistance, the feature of resistance to mould.
General special power supply cable insulation 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
The purpose of this utility model is to provide the wear-resisting feed cable of the extraordinary soft high-low temperature resistant in a kind of field, completely possesses softness, high-low temperature resistant, wear-resisting, salt spray resistance, the feature of resistance to mould, meets the military specific demand of China.
Scheme of the present utility model is as follows: a kind of field wear-resisting feed cable of extraordinary soft high-low temperature resistant, be enclosed with dynamic perduren insulating barrier outside described conductor respectively and form core, two stranded bunchys of core after wrap insulate layer, the belting layer that after bunchy, arranged outside has fire-retardant oxygen barrier band overlapping wrapped, tinned copper wire screen is set outside described belting layer and forms core group, wrapped belting layer II after three core combinations, outside described belting layer II, the inner sheath that high temperature resistant polyurethane extrudes formation is set, the armour of tinned copper wire braiding is set outside described inner sheath, high temperature resistant polyurethane external sheath layer is enclosed with outside described armour, flame retardant type glass cord is filled with between described belting layer II and core group, three nylon ropes are also provided with between three described core groups,
Some polyurethane reinforcements are set outside described external sheath layer.
Further, described belting layer and belting layer II adopt the overlapping wrapped formation of one or more layers fire-retardant oxygen barrier band.
Further, described conductor adopts the 5th class conductor, strandedly to form by the zinc-plated soft circular copper wire of 6-22 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 described urethane jacket layer also arranges fluorescent belt outward.
The utility model can meet working temperature-55 DEG C ~+105 DEG C, can Long-Time Service (>=95%RH) bitter edible plant in coastal wet environment, and also can reel dragging simultaneously in the wild for a long time; Also be provided with three nylon ropes between three core groups, have doing to turn round and drawing performance of the raising cable that can imitate.Meanwhile, the utility model also has the following advantages:
1, conductor adopts five class conductors, and this kind of conductor adopts that the zinc-plated soft circular copper wire of multiply is regular strandedly to be formed, and feature is structurally flexible, has little, the convenient feature of installing 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, interior oversheath adopts special high temperature-resistant polyurethane (TPU), and the maximum feature of this material is exactly wear-resisting, high-low temperature resistant (-55 ~ 105 DEG C), very high tensile strength (>=20Mpa) hydrolysis, meets the requirement of salt spray resistance, mould simultaneously.
4, the reinforcement arranged, can avoid the further wearing and tearing of sheath in heave.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of field wear-resisting feed cable of extraordinary soft high-low temperature resistant, be enclosed with dynamic perduren insulating barrier 2 outside conductor 1 respectively and form core, two stranded bunchys of core after wrap insulate layer, the belting layer 3 that after bunchy, arranged outside has fire-retardant oxygen barrier band overlapping wrapped, tinned copper wire screen 4 is set outside belting layer 3 and forms core group, wrapped belting layer II 5 after three core combinations, the inner sheath 6 that high temperature resistant polyurethane extrudes formation is set outside belting layer II 5, the armour 7 of tinned copper wire braiding is set outside inner sheath 6, high temperature resistant polyurethane external sheath layer 8 is enclosed with outside armour 7, flame retardant type glass cord is filled with between belting layer II 5 and core group, three nylon ropes 9 are also provided with between three core groups, some polyurethane reinforcements 10 are set outside described external sheath layer 8.
