Together it is twisted with the monofilament of auxiliary core conductor, and direction of lay is consistent.
Further, power wire core metal screen layer and auxiliary core metal screen layer by metal and fibrage and
Into, and also serve as the wire core of cable.
Further, the outer jointing jacket for being extruded in cable core body exterior is protection outside the haloflex with high intensity
Set.
High strength fibre in such scheme refers to that carbon fiber or glass fibre etc. have the fiber of high intensity, and use is this
The fiber of high intensity, which substitutes existing steel wire rope, can improve the flexibility of cable, and pulling force, lateral pressure and anti-are born in cable
In the environment for deflecting motion again, the service life of shuttle car cable is improved.
Compared with prior art, the beneficial effects of the utility model are:
1st, the utility model with the addition of high strength fibre strengthening core in power wire core conductor and auxiliary core conductor, right
Conductor directly plays humidification so that cable is resistant to alternating bending and stretched and not easy to break;
2nd, the utility model optimizes design to power wire core conductor and the respective lay configuration of auxiliary core conductor, i.e.,
Power wire core conductor and auxiliary core conductor monofilament are that same direction is twisted with high strength fibre strengthening core, substantially improve it
Flexibility, improve the adaptability that power wire core conductor and auxiliary core conductor are required shuttle car Special use;
3rd, the utility model is among cable core body and power wire core and the surrounding of auxiliary core set high strength fibre
Gasket for packing can greatly improve the stretching resistance of cable, and high strength fibre gasket for packing both can play protection to the insulated wire cores of cable and make
With again so that the overall rounding property of cable is more preferable.
