Abstract
The utility model provides a super fire-resistant carbon fiber control cable, which has the advantages of good flame-retardant performance, good insulation, high breakdown voltage, corrosion resistance and excellent anti-jamming performance. In the technical scheme, a PTFE insulation layer is extruded and coated on the surface of a mica tape outside a tinned copper wire connector to form a cable core, a filler and a glass tape cladding layer are arranged outside a cable-forming layer, a copper wire composite tape shielding layer is arranged outside the glass tape cladding layer, a fire-resistant mica tape cladding layer is arranged outside the shielding layer, an inner sheath and an outer sheath are arranged outside the fire-resistant mica tape cladding layer, and a carbon fiber layer is arranged between the inner sheath and the outer sheath. The utility model can be widely used in the fire-resistant environment for installation of transmission lines during the construction of the power plant, transmission and distribution project, petrochemical, metallurgy, steel, high-rise building and other large-scale projects.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of superfine fire safe type carbon fibre control cable.
Background technology
Existing cable kind is a lot, mainly is made of insulating barrier that comprises conductor and conductive surface and oversheath etc., and its fire resistance is relatively poor.Natural calamity was brought the loss of the quilt that can not cover to people in recent years, some fields, fire-resistant requirement to cable is more and more higher, used cables of industry such as electronics, the energy, petrochemical industry, metallurgy, electric power particularly, because long-term exposed circuit of working outside is more, to the heat resistance an urgent demand of cable.Past, of common occurrence because of the situation of the thermo-labile breaking out of fire accident of electric wire, caused very big loss for country, business property, give the people's life security also with very big harm.In the construction of heavy constructions such as modernized power station, metallurgy, chemical industry, all need a large amount of cables, and the fire-resisting cable of serviceability excellence just can be guaranteed engineering construction quality and produce safe in utilization.In addition, along with science and technology and rapid development of economy, people enjoy the conveniently while that the electrical equipment household electrical appliances bring, and have also buried immeasurable potential safety hazard.With common fire-resisting cable is example, and under the effect that common refractory uses, cable just stops burning things which may cause a fire disaster to be burned to cable on certain hour.So, research and develop out the fire-resistant wire and cable of use excellent performance, satisfy the demand in market, be a urgent task of cable scientific research institution and manufacturing enterprise.
Summary of the invention
The utility model purpose is to overcome the deficiency that common fire-resisting cable exists, and a kind of have good flame retardation effect, good insulation preformance, puncture voltage height, corrosion-resistant, novel fire-resistant, resistant to elevated temperatures cable that interference free performance is good are provided.
The utility model purpose is achieved in that a kind of superfine fire safe type carbon fibre control cable, the outer mica tape of the tinned copper wire conductor of this cable surface extrudes the teflon insulation layer and makes cable core, outside the stranding layer, be provided with inserts and glass tape lapping layer, the glass tape lapping layer is provided with copper wire composite band screen outward, screen is provided with the fire-resistant isinglass belt lapping layer outward, the fire-resistant isinglass belt lapping layer is provided with inner sheath and oversheath outward, is provided with carbon fiber layer between the inside and outside sheath.
Insulating barrier of the present utility model has adopted carbon fiber, and this material fusion just occurs and incombustible state being heated to 1500 ℃, and common fire-resisting cable be pvc material, can not keep out the burning of high temperature.
Beneficial effect: the utility model is rational in infrastructure simple, and the manufacturing is easy, cable has less insulation dielectric loss and good shielding properties, and its shielding transfer impedance is in the 100MHz scope; Be not more than 1 Ω/m, and have good flame retardant property; Cable has stronger fire resistance and insulation property; Resistance to elevated temperatures; Decay resistance; Construction of cable compactness, rounding; Safe in utilization, the performance requirement with cable of modernization project in building can be satisfied fully, the fire-resistant environment of the demand transmission line installation down in the construction of heavy constructions such as power plant, transmission and transformation engineering, petrochemical industry, metallurgy, iron and steel, skyscraper can be widely used in.
