Abstract
The utility model discloses a fireproof silicon rubber insulated cable for aerospace. The fireproof silicon rubber insulated cable for aerospace is characterized in that a silicon rubber insulating layer (4) wraps a copper conductor (1) in an extruding manner to form an insulated wire core, wherein fireproof mica tapes (2) and non-woven fabric layers (3) sequentially wrap the copper conductor (1) and the silicon rubber insulating layer (4); a plurality of wire cores are twisted to form a cable core; and a mica tape fireproof layer (5) and a silicon rubber sheath (6) sequentially wrap the cable core. The cable has the properties such as excellent heat resistance, cold resistance, dielectric property, ozone resistance and resistance to atmospheric aging, and has excellent electric insulating property; the electric insulating property of silicon rubber is stable even if the temperature and the frequency change or the insulated cable becomes damp; and the silica generated after burning is still an insulator.
Description
Technical field
The utility model relates to a kind of Aero-Space fire-resistant silicon rubber insulated cable, particularly Aero-Space silicon rubber insulated cable; Belong to technical field of electric wires and cables.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all over 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes in the world first electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.
China's economic growth continuously and healthily, 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 the 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 industry also has huge development potentiality.
In numerous synthetic rubber, silicon rubber is outstanding person therein.It has tasteless nontoxic, is not afraid of high temperature and resists the characteristics of severe cold, and " keeping cool ", " remaining calm " when 300 degrees centigrade and subzero 90 degrees centigrade are not still lost original intensity and elasticity.Silicon rubber also has good electrical insulating property, oxytolerant ageing resistance, fast light ageing resistance and mildew resistance, chemical stability etc.Owing to having had these excellent performances, make silicon rubber bring into play important function in economic development.Silicon rubber has the excellent performances such as thermal endurance, cold resistance, dielectricity, anti-ozone and anti-atmospheric aging, and the outstanding performance of silicon rubber is that serviceability temperature is broad, can be-60 ℃ (or lower temperature) to+250 ℃ (or higher temperature) lower long-term the use.Silicon rubber has good electrical insulation capability, even when temperature and frequency change, or when making moist, the electrical insulation capability of silicon rubber is C.T still; And still be insulator at the silicon dioxide that burning generates afterwards.This is very favorable to cable for aerospace.
The utility model content
The technical problem that the utility model solves is to provide a kind of Aero-Space with anti-ozone, anti-atmospheric aging and fire-resistant silicon rubber insulated cable.
The purpose of this utility model is achieved through the following technical solutions:
Aero-Space fire-resistant silicon rubber insulated cable, its design feature are, extrude silicone rubber insulation layer by copper conductor and consist of insulated wire cores, and described copper conductor and silicone rubber insulation layer are coated with fire-resistant isinglass belt and nonwoven layer outward successively; Consist of cable core by many cores are stranded, described cable core is coated with mica tape flame retardant coating, silicone rubber jacket outward successively.
The utility model design feature also is:
Described copper conductor adopts the annealed copper material.
The utility model beneficial effect is embodied in:
1, the utility model insulation and sheath adopt silicon rubber, and silicone rubber cable has the excellent performances such as thermal endurance, cold resistance, dielectricity, anti-ozone and anti-atmospheric aging; And silicon dioxide ashes that after silicon rubber burning, generation is not fired and certainly putting out, having insoluble characteristic, its ashes thing is still the insulator of bone lattice structure, is coated on lastingly on wire, has good insulation property; This is very favorable to cable for aerospace.
2, the utility model is surrounded with the flame retardant coating that two-layer fire-resistant isinglass belt consists of outside conductor, is coated with nonwoven fabric belts outside flame retardant coating, and nonwoven fabric belts is not come off in the time of protecting mica tape to be subject to external force.
3, the utility model conductor adopts the 5th kind of annealed copper conductor, to improve elongation, to reduce D.C. resistance, the lay ratio of conductor employing simultaneously is 12～14 times, twist together with less lay ratio that (single line rotates a circle the distance of being advanced twisting pitch around the twisted wire axis, pitch is lay ratio with the ratio of conductor diameter), bending property and the softness of raising cable.
4, the utility model before extruding silicone rubber jacket, is surrounded with the flame retardant coating that one deck fire-resistant isinglass belt consists of.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 copper conductor, 2 mica tapes, 3 nonwoven layer, 4 silicone rubber insulation layers, 5, mica tape, 6 silicone rubber jackets.
Technical solutions of the utility model are described further by embodiment below in conjunction with accompanying drawing.
Embodiment
As shown in Figure 1, cable is comprised of copper conductor 1, mica tape 2, nonwoven layer 3, silicone rubber insulation layer 4, mica tape 5, silicone rubber jacket 6.
In concrete enforcement, the 5th kind of annealed copper of copper conductor 1 use consists of with 12～14 times of bundle strands of lay ratio, is surrounded with the flame retardant coating that fire-resistant isinglass belt 2 consists of on conductor, is surrounded with the nonwoven fabrics protective layer outside mica tape, and its outer silicone rubber insulation layer 4 that extrudes adopts continuous vulcanization; The edge core stranded formation cable cores together that thoroughly do away with are surrounded with the flame retardant coating that mica tape 5 consists of more outside cable core, extrude high-strength tear-resistant and split silicone rubber jacket 6.This cable has the excellent performances such as thermal endurance, cold resistance, dielectricity, anti-ozone and anti-atmospheric aging, and has good electrical insulation capability, even when temperature and frequency change, or when making moist, the electrical insulation capability of silicon rubber is C.T still; And still be insulator at the silicon dioxide that burning generates afterwards.
