Problems solved by technology

[0004] During the use of the vertical lifting equipment, the equipment runs upwards and the cables hang down. Due to the action of gravity and the back-twisting action of the cables from the coiled state to the return state, the conductor and insulation will become longer; and when the equipment descends, the gravity will be cancelled. Finally, the insulation will be restored due to its own rebound effect, but the conductor will not be restored to form a length difference. Over time, the conductor will bulge; in addition, the use of non-woven fabrics for wrapping will result in a small bending radius of the cable, which is easy to bulge

Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, a multi-core mobile rubber-sheathed cable includes a cable core in the center of the cable, and the cable core is composed of multiple cores and wax wires 6 for binding multiple cores. An inner conductor 1 made of aramid fiber bundles is provided with an isolation layer 3 and an insulating layer 4 is extruded outside the inner conductor. Aramid filament filling 5 is arranged in the gap of the cable core, and the wrapping tape 7 and the extruded outer sheath 8 are sequentially wound outside the cable core; the aramid filament is arranged in the center of the inner conductor. The aramid filament filling is composed of aramid filament and a rubber layer extruded outside the aramid filament.

[0013] When assembling, first combine a plurality of aramid filaments and wire bundles into an inner conductor 1; then extrude an insul...

Abstract

The invention discloses a movable multi-core rubber sleeve cable, which comprises a cable core in the center of the cable, wherein the cable core consists of a plurality of conductor cores and wax lines for binding the plurality of conductor cores, a gap of the cable core is filled with aramid fibers, a wrapping band and an extruding outer jacket are sequentially arranged outside the cable core, the middle of the cable core is provided with an inner conductor added with aramid fiber bundles, and an insulation layer is extruded on the outer surface of the inner conductor. The aramid fibers are added in the inner conductor, the conductor is prevented from lengthening in a bending process, the protruding of an insulated wire core can not be caused, and the conductor can not be broken due to the protruding of the insulated wire core, thus the service life is prolonged.

Description

[0001] technical field [0002] The invention relates to a cable, specifically a 300 / 500V rubber-sheathed cable for driving or electric hoists. Background technique [0003] Due to the implementation of the GB / T5013-2008 standard, the rubber cable is suitable for 450 / 750 and below household appliances, electric tools and various mobile electrical equipment. However, the lines for driving, electric hoist, and vertical lifting are frequently moved and have high requirements for use. Ordinary rubber cables have problems such as bulging of the outer sheath, broken core, and short service life after being used for a period of time, which affects the normal operation of the vertical lifting equipment and poses safety hazards. The reasons for the above defects are as follows: [0004] During the use of the vertical lifting equipment, the equipment runs upwards and the cables hang down. Due to the action of gravity and the back-twisting action of the cables from the coiled state to ...
