The utility model effectively strengthens the function of high-temperature resistance, can bear the temperature below 150 DEG C, and can normally work. The utility model can not produce harmful gases of halogen hydride, and the like when being ignited, a shielding system which is made of high-temperature resistant materials and corrosion prevented materials and provided with a short-circuit protection structure inside is arranged in the cable, thereby the utility model effectively avoids breakdown or damage caused by strong thunderbolt magnetic effect voltage, and improves the sensitivity of a line road-side over-current protection device.
Description
Technical field
The utility model relates to a kind of flexible cable that is used for signal transmission, and particularly a kind of have a signal transmission flexible cable high temperature resistant, grease proofing, anti-corrosion function.
Background technology
At present, the various power cables outside of extensive use all is enclosed with one deck cable insulation in many buildings at home.All contain halogen mostly in the cable insulation material, after such insulating material is lighted, can produce thick smoke and the very strong hydrogen halide of corrosivity, jeopardize people's life, in case harm equipment and contaminated environment are breaking out of fire in the building, both entail dangers to life also can serious environment pollution.
The utility model content
The purpose of this utility model is that a kind of safety cable that has high temperature resistant, grease proofing, anti-corrosion function, still can keep energising under specific disaster scenario will be provided.The utility model relates to a kind of comprehensive flexible cable high temperature resistant, grease proofing, anti-corrosion function that has, comprise the cable inner core and wrap in the outer cable outer layer of cable inner core, state cable inner core inside and be followed successively by conductor wire core and insulating barrier from inside to outside, described cable outer layer inside is followed successively by insulation internal portioning layer, screen and oversheath from inside to outside, is provided with refractory filler in the space between described cable outer layer and the cable inner core.The number of the cable inner core in the described cable outer layer is one or more.The material of described conductor wire core is the high purity oxygen free copper bar.Described refractory filler is the glass rope.Described insulating barrier is the crosslinking with radiation material.Described insulation internal portioning layer is the high flame retardant band that the outside is surrounded by the polytetrafluoroethylene membrane band.Described copper wire copper strips combination screen is made up of some naked soft copper wires or the nonmagnetic soft metal of coating fine rule.The material of outer jacket is the synthetic fourth eyeball plastics of flame retardant type rubber and plastic.The utility model has effectively strengthened high temperature resistant function, can bear the temperature below 150 degrees centigrade, and can operate as normal.Even if can not produce pernicious gases such as hydrogen halides after being lighted yet; has the shielding harness that exotic material and anti-corrosion material inside are provided with the short-circuit protection structure in the cable; puncture or the damage of effectively having avoided powerful thunder and lightning magnetic effect voltage to be caused; improved the sensitivity of circuit road end overcurrent protective device; reached the designing requirement of environmental type safety cable; be widely used in the building such as hospital, boats and ships, power station, subway, tunnel, be applied to the intensive place of equipment that mine, metallurgy, petrochemical industry etc. have relatively high expectations to fire safety etc.
Description of drawings
Accompanying drawing 1 is provided with four section of structures under the cable inner core situation in the utility model.
Embodiment
Has comprehensive flexible cable high temperature resistant, grease proofing, anti-corrosion function, comprise the cable inner core and wrap in the outer cable outer layer of cable inner core, described cable inner core inside is followed successively by conductor wire core 1 and insulating barrier 2 from inside to outside, described cable outer layer inside is followed successively by insulation internal portioning layer 4, screen 5 and oversheath 6 from inside to outside, is provided with refractory filler 3 in the space between described cable outer layer and the cable inner core.
The number of the cable inner core in the described cable outer layer is one or more.
The material of described conductor wire core is the high purity oxygen free copper bar, and the number of the cable inner core in the described cable outer layer is one or more, generally selects three or four.Conductor wire core is to manufacture through naked copper fine rule after softening or coated naked copper fine rule bundle strand.The cross section of conductor wire core is circular, and its sectional area is 0.5～4mm
2, the physical strength height of conductor wire core, mechanical performance is strong, good stability, its shape is constant, but very little to the curvature influence of cable.
Described refractory filler is the glass rope, and this is a kind of non-hygroscopic filler, both can be high temperature resistant, can guarantee the rounding full weight of whole cable again.Described fire-resistant twining package tape is a glass fibre belt.
Described insulation internal portioning layer is resistant to elevated temperatures special twining package tape.
Described insulating barrier is the crosslinking with radiation material, as the polythene radiation-crosslinking CABLE MATERIALS.Described insulating barrier is a kind of special insulation material, and its oxygen index can anti-150 celsius temperatures more than 90.Be coated on the outside of flame retardant coating, by crosslinked special processing, change polyethylene line style molecular structure into upright network molecular structure, improved the electric property of product greatly, physical property, mechanical performance and other properties, not only high temperature resistant and have the advantages that to be not easy to spread and can not produce hydrogen halide, cable just can not discharge harmful smog, unlikely causing " secondary disaster " when burning like this.
Described insulation internal portioning layer is the high flame retardant band that the outside is surrounded by the polytetrafluoroethylene membrane band, and described insulation internal portioning layer comprises two-layer band, and inboard one deck is the high flame retardant band, and is closely overlapping wrapped outside the cable inner core; Outside one deck is a polytetrafluoroethylene membrane, and is closely overlapping wrapped outside the high flame retardant band.
Described screen is formed by some naked thin copper wires or the braiding of the nonmagnetic soft metal of coating fine rule; the maskable cable can anti-electromagnetic induction; imperfect earth and power line conducted interference; reduce puncture or damage that inductance avoids powerful big thunder and lightning magnetic effect voltage to be caused; prevent that induced electromotive force is excessive; copper wire copper strips combination screen had both played and had suppressed the externally effect of emission of electromagnetic wave, can be used as the passage of short circuit current again, can play the protective effect of neutral core.
The material of outer jacket is a kind of Halogen rubber and plastic compound material, i.e. the synthetic fourth eyeball rubber-plastic of flame retardant type rubber and plastic can anti-150 celsius temperatures, have grease proofing, anti-corrosion function.Therefore outer jacket can be high temperature resistant, slowed down hot conduction, and behind 90min, temperature inside also can not surpass 150 degree under the high-temperature condition, from performance and useful life considerably beyond common flame-retardant sheath.
The utility model cable has multiple functions such as high temperature resistant, grease proofing, anticorrosion, normal transmission equipment signal, alarm signal, electric current etc. effectively when it runs into accident.When particular surroundings was worked, the utility model had more superpower anti-resistive energy to heavy oil, strong acid, highly basic, even also can keep the safety cable of energising under specific disaster scenario.
