Abstract
The utility model discloses a kind of field high strength flexible cable in the cable technology field, comprise oversheath, band and three core cables of being provided with from outside to inside, the core cable wrap draw together insulating barrier and with the conductor of the concentric setting of insulating barrier, described conductor forms by some tinned copper wires are stranded, is provided with some high strength aramid fiber silks between the described tinned copper wire.Fill in the utility model and adopt high strength aramid fiber silk, its tensile strength is 2800MPa, percentage elongation is 2.5%, performance surpasses steel wire, and high strength aramid fiber silk is very thin, has good flexibility, and it is arranged on the tensile strength that can significantly increase cable in the core cable, simultaneously, its flexibility to cable does not have influence; Take into account the double requirements that the prerequisite flexibility of open-air mobile occasion is good and intensity is high during the utility model design, thereby be particularly suitable for moving field use in the open air.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of novel field high strength flexible cable.
Background technology
Field of the prior art flexible cable mainly is made of oversheath, band, core cable etc. from outside to inside, and the core cable is common more than three, and the core cable constitutes by insulating barrier with the conductor of the concentric setting of insulating barrier, and conductor forms via some tinned copper wires are stranded.Its deficiency is: pull frequently when using cable owing to the field, the pulling force that cable is subjected to is very big, common field flexible cable resistance to tension deficiency, thereby the life-span is shorter.
The utility model content
The purpose of this utility model provides a kind of novel field high strength flexible cable, makes it have very high intensity, guarantees that simultaneously the flexibility of cable does not reduce.
The purpose of this utility model is achieved in that a kind of field high strength flexible cable, comprise oversheath, band and three core cables of being provided with from outside to inside, the core cable wrap draw together insulating barrier and with the conductor of the concentric setting of insulating barrier, described conductor forms by some tinned copper wires are stranded, is provided with some high strength aramid fiber silks between the described tinned copper wire.
Fill in the utility model and adopt high strength aramid fiber silk, its tensile strength is 2800Mpa, percentage elongation is 2.5%, performance surpasses steel wire, and (intensity of steel wire is 2000Mpa, percentage elongation is 2.0%), and high strength aramid fiber silk is very thin, has good flexibility, it is arranged on the tensile strength that can significantly increase cable in the core cable, simultaneously, its flexibility to cable does not have influence, has taken into account the double requirements that the prerequisite flexibility of open-air mobile occasion is good and intensity is high during the utility model design, thereby is particularly suitable for moving field use in the open air.
As further improvement of the utility model, be provided with high strength aramid fiber silk between the described core cable and between band and the core cable.The tensile property of cable can be further strengthened in this design, prolongs its useful life, works to fill the rounding cable simultaneously.
Description of drawings
Fig. 1 is the utility model sectional drawing.
Wherein, 1 oversheath, 2 bands, 3,3 ' high strength aramid fiber silk, 4 insulating barriers, 5 tinned copper wires.
Embodiment
As figure, be field high-strength special type flexible cable, comprise neoprene oversheath 1, glass fibre band 2 and three core cables of being provided with from outside to inside, the core cable constitutes by insulating barrier 4 with the conductor of the concentric setting of insulating barrier, conductor is by some tinned copper wire 5 stranded forming, 5 of tinned copper wires are provided with some high strength aramid fiber silks 3, also be provided with between the core cable and between band 2 and the core cable high strength aramid fiber silk 3 '.
Above-mentioned core cable also can be any many more than three.
Claims (2)
1, a kind of field high strength flexible cable, comprise oversheath, band and at least three core cables of being provided with from outside to inside, the core cable wrap draw together insulating barrier and with the conductor of the concentric setting of insulating barrier, described conductor forms by some tinned copper wires are stranded, it is characterized in that: be provided with some high strength aramid fiber silks between the described tinned copper wire.
2, a kind of field according to claim 1 high strength flexible cable is characterized in that: be provided with high strength aramid fiber silk between the described core cable and between band and the core cable.
