Description
Technical Field
The utility model relates to a high temperature resistant tensile installation shielded wire is the control wire who is arranged in the high temperature high strength system of certain communication equipment signal transmission.
Background
Under the prior technical conditions, the high-temperature resistant and tensile wires are two different types of wires respectively, and the technical background is as follows:
ordinary high temperature resistant electric wire comprises the inside work part of conductor, insulation composition cable, and material multilayer such as add polyimide film, mica tape according to the product requirement again suitably wraps the package and constitutes heat-proof part, and outermost protective layer such as sheath still needs protects thermal insulation material, causes that cable overall structure size is big, the weight is heavy, inconvenient installation operation.
The common high-temperature-resistant wire is formed by extruding or multi-layer wrapping high-temperature-resistant fluoroplastic (temperature resistant grade is 200-250 ℃) outside a conventional conductor, the series of materials are high in price and relatively high in hardness (Rockwell hardness R25), and an insulated single wire is hard and is not easy to bend or peel and weld after extrusion or multi-layer wrapping. In order to further improve the temperature-resistant grade, a plurality of layers of polyimide films (with the temperature-resistant grade of 220-300 ℃) and flame-retardant mica tapes (with the hardness of 2.8-3.2) can be properly wound outside the insulation, wherein the mica tapes are used for preventing the polyimide films from melting under the condition that the temperature of the electric wire is suddenly increased, and finally, a layer of sheath (mostly made of fluoroplastic materials) with a certain temperature-resistant effect is extruded according to the requirements of products after cabling to protect the temperature-resistant isolation layer. The finished wire product has larger relative outer diameter, heavy weight, higher hardness, difficult bending and multiple inconvenience for subsequent processing and installation operation.
Ordinary tensile electric wire is the conductor that is twisted with metallic conductor jointly by aramid fiber silk and forms, extrudes the inside work part of constituteing the electric wire after insulating again, can suitably add the shielding layer as required outside insulating, and outmost needs the sheath to protect cable inside, causes that cable overall structure size is big, direct current resistance is on the high side.
In the common tensile wire, a proper amount of aramid fiber yarns (the tensile force is about 220N/cord) need to be twisted in a conventional conductor to meet the tensile force requirement, and then the procedures of insulating extrusion and the like are carried out. Although the electric wire has certain tensile capacity, the aramid fiber wire is made of non-metal materials, the outer diameter of the aramid fiber wire is not easy to control, the outer diameter of the aramid fiber wire is larger after the aramid fiber wire is extruded and insulated, and the direct current resistance of the whole electric wire is higher than that of a pure metal conductor due to the fact that the non-metal materials are arranged in the conductor.
Under the prior technical conditions, if one cable needs to meet two requirements of high temperature resistance and tensile strength, the two common electric wires are bundled or stranded together according to product requirements to form a comprehensive cable, so that the size is increased structurally, the overall weight is increased, welding or overall installation is not convenient in subsequent processing and use of the cable, higher requirements are provided for connectors such as connectors, and the problems of high manufacturing cost, complex process and the like are caused.
Disclosure of Invention
In view of the situation of the prior art and the correction of the existence, the utility model provides a high temperature resistant tensile installation shielded wire, the problem solved is: the electric wire can transmit sound, data signals and the like at the same time, and the electric wire has the advantages of being small in structural size, light in weight, soft and the like, and is high in temperature resistance and tensile strength.
The utility model discloses a realize above-mentioned purpose, the technical scheme who takes is: a high-temperature resistant tensile installation shielding wire comprises a high-temperature resistant tensile conductor, and a high-temperature resistant insulating layer, a high-temperature resistant tensile composite protective layer and a high-temperature resistant tensile shielding layer are sequentially arranged outside the high-temperature resistant tensile conductor.
The high-temperature resistant tensile conductor is formed by stranding a plurality of strands of high-strength nickel-plated copper alloy wires.
The high-temperature-resistant insulating layer is made of high-temperature-resistant aramid paper.
The high-temperature-resistant tensile composite protective layer is formed by coating organic silicon paint outside a glass fiber braided layer.
The high-temperature resistant tensile shielding layer is a high-strength nickel-plated alloy wire braid layer.
The utility model has the advantages that:
the utility model discloses the electric wire is the product that satisfies two kinds of technical requirement simultaneously according to reasonable calculation and manufacturing in the electric wire that will have two kinds of different technical requirement respectively in the technique in the past, and because simple structure, it is lower to the connector requirement, has reduced the cost greatly, and still has certain anti-electromagnetic interference ability.
1. The conductor adopts multi-strand high-strength nickel-plated copper alloy wires, has excellent conductivity, higher temperature resistance level and high tensile strength. The stranded conductor has a certain stranding rate, and has higher flexibility compared with a single conductor, so that the conductor is not easy to break when the cable is bent; compared with the common pure copper conductor, the nickel-plated copper alloy conductor has almost the same direct current resistance under the condition of the same section, thereby effectively ensuring the transmission of signals and power supply; the nickel-plated copper alloy conductor can form a layer of NiO protective film at normal temperature, so that the nickel-plated conductor can generate obvious high-temperature oxidation phenomenon when being heated to 500 ℃; compared with the common pure copper conductor, the nickel-plated copper alloy conductor has higher tensile strength (which can be improved by 200-300% under the condition of the same section and outer diameter), and can meet certain tensile force requirement without adding aramid fiber.
2. The insulating layer adopts high temperature resistant aramid fiber paper to wind the package, has good electrical property, has very high temperature resistant grade (450 ℃ can progressively carbonize at high temperature and can not melt, decompose) and relative plastics material's insulation simultaneously, is lighter under the prerequisite of guaranteeing electrical property, and is more soft.
3. The protective layer is formed by compounding two materials of glass fiber and organic silicon paint, the glass fiber has high tensile strength (the strength is generally 5N/2 strands), and the glass fiber has high temperature resistance (temperature resistance is 500-1000 ℃). However, the glass filaments themselves are brittle and can be locally broken under high transverse forces. Therefore, after the glass fiber is woven, the organic silicon paint is dipped and coated, gaps and surfaces of the glass fiber are fully filled, and the glass fiber is prevented from being broken and fluffed due to reprocessing; then high-temperature sintering is carried out to evenly shape the organic silicon paint, and the sintered and shaped organic silicon paint also has higher temperature resistance registration (temperature resistance is 400-1200 ℃); the composite protective layer not only improves the temperature resistance level and the tensile strength of the product, but also is thinner and lighter, and effectively reduces the outer diameter of the product.
4. The shielding adopts high-strength nickel-plated copper alloy wires, so that the anti-electromagnetic interference capability is strong, and the high tensile strength of the wire is ensured.
In a word, the wire breaks through the independent and single structural design of the conventional common high-temperature-resistant and tensile-resistant wire, can have the characteristics of high temperature resistance and tensile resistance, reduces the weight of the wire (30% lighter than two common wires), reduces the outer diameter of the wire (30% smaller than the outer diameters of the two common wires), meets the requirements of temperature and tensile force, is more convenient to operate and construct, and saves the cost.
