Abstract
The utility model discloses a butyronitrile insulation and sheath electric flexible cable. The cable comprises a cable core which is formed by a plurality of conductors which each is coated by a butyronitrile insulation layer and which are stranded into a harness, wherein a thermoplastic polyurethane anti-extrusion layer is formed outside the cable core by extrusion moudling, a steel wire woven layer and a butyronitrile sheath layer are sequentially arranged outside the anti-extrusion layer, rope-shaped elastomers which are made of polyurethane by extrusion moudling is circumferentially distributed in the butyronitrile sheath layer, and the elastomer is internally provided with an alloy wire. According to the utility model, the cable has a novel structure, in which the thermoplastic polyurethane anti-extrusion layer is formed outside the cable core by extrusion moudling, and the elastomers having alloy wires are additionally arranged inside the butyronitrile sheath layer, so that the bend resistance and tensile performance of the cable are improved, and the flexibility of the cable is ensured to be not influenced, thereby prolonging the service life.
Description
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of butyronitrile insulation and sheath electrical flexible cable.
Background technology
power set are operated under the condition of high temperature, because the production environment temperature is high, cable insulation is easily aging, reduced the useful life of cable design, improved the cable replacement frequency, in production, cable running time under the time limit that cable useful life normally uses according to cable design and varying environment, determine according to experience, for fear of the cable accident of bursting apart, increase coefficient of safety, cable value in useful life is less, replacement cycle is short, because power set need a large amount of power cable and control cables, replacement frequency is very high, change the power set cable and need a large amount of manpowers, thereby shorten the replacement cycle and move, increased cable cost, wasted manpower, increased the maintenance off-time, reduced production efficiency.
The too early bending failure of conductor and fracture just occured in one month in the even less than that has, and how to improve anti-song level, the stretch-proof performance of such cable, and selection and the architecture advances of how to carry out material are present problem demanding prompt solutions.
The utility model content
The utility model purpose is to provide a kind of butyronitrile insulation and sheath electrical flexible cable, and is simple in structure, under on the less prerequisite of cable flexibility impact, improved anti-song level, the stretch-proof performance of cable.
The utility model is achieved through the following technical solutions:
Butyronitrile insulation and sheath electrical flexible cable, include cable core, it is characterized in that: described cable core has the many mutual stranded bunchys of conductor that coat the butyronitrile insulating barrier to consist of, the cable core extrusion moulding is in the thermoplastic polyurethane anti-extrusion layer, anti-extrusion layer is provided with steel wire braid, butyronitrile restrictive coating outward successively, along annular spread, the polyurethane extrusion moulding being arranged in the butyronitrile restrictive coating is funicular elastomer, is provided with B alloy wire in elastomer.
Described butyronitrile insulation and sheath electrical flexible cable, it is characterized in that: described cable conductor adopts zinc-plated or zinc-plated copper wire.
The utility model has the advantages that:
The utility model novel structure, cable core is passed through extrusion moulding in the thermoplastic polyurethane anti-extrusion layer, and set up elastomer with B alloy wire in the butyronitrile restrictive coating, anti-song level, the stretch-proof performance of cable have been improved, the flexibility that has also guaranteed cable is unaffected, has extended useful life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
as shown in Figure 1, butyronitrile insulation and sheath electrical flexible cable, include cable core, cable core has the many mutual stranded bunchys of conductor 1 that coat butyronitrile insulating barrier 2 to consist of, the cable core extrusion moulding is in thermoplastic polyurethane anti-extrusion layer 3, buffer capacity when greatly having improved outer bound pair cable extruding, can be good at protecting cable core injury-free, the outer steel wire braid 4 that is provided with successively of anti-extrusion layer 3, butyronitrile restrictive coating 5, butyronitrile restrictive coating 5 is interior, and along annular spread, the polyurethane extrusion moulding to be arranged be funicular elastomer 6, be provided with B alloy wire 7 in elastomer 6, improved the anti-song level of cable, the stretch-proof performance.
Claims (2)
