Light winding drum flat cable with high tensile resistance and resistant to bending

Abstract

The invention discloses a light winding drum flat cable with high tensile resistance and resistant to bending. The cable comprises wire cores and a sheath layer, wherein a plurality of wire cores are arranged in parallel and are all coated in the sheath layer, the cross section of the sheath layer is of a long waist shape, each wire core comprises a reinforcement core, a conductor layer and an insulation layer, the conductor layer is formed by winding a plurality of conductor wires at the periphery of the reinforcement core, and the insulation layer wraps the periphery of the conductor layer. The cable has the characteristics of high tensile resistance, flexibility, bending resistance, oil resistance and flame retardancy.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a light-duty high tensile and bending resistant reel flat cable. Background technique [0002] At present, after domestic reel cables are used for a period of time after repeated curling and retracting, there will be problems such as conductor distortion, bulging and broken cores, which will make the reel cables unable to continue to be used. In order to improve the tensile performance of the cables, the traditional reel cables are all It is to add steel wire rope to the conductor to improve the tensile performance of the cable conductor, but due to the high density of steel, the weight of the cable will increase greatly after adding the steel wire rope, and even the reel motor cannot be started, which brings equipment and energy. Great loss. In addition, aramid yarn is added to the conductor. Although the aramid yarn is lighter in weight, its texture is soft and can only be mixe...

Problems solved by technology

[0002] At present, after domestic reel cables are used for a period of time after repeated curling and retracting, there will be problems such as conductor distortion, bulging and broken cores, which will make the reel cables unable to continue to be used. In order to improve the tensile performance of the cables, the traditional reel cables are all It is to add steel wire rope to the conductor to improve the tensile performance of the cable conductor, but due to the high density of steel, the weight of the cable will increase greatly after adding the steel wire rope, and even the reel motor cannot be started, which brings equipment and energy. big loss

In addition, aramid yarn is added to the conductor. Although the aramid yarn is lighter in weight, its texture is soft and can only be mixed into the conductor. Although it can strengthen the tensile strength, it cannot support the conductor and protect it The effect of winding a conductor on it at a smaller pitch

Moreover, copper is a material with high plasticity. It cannot automatically return to its original shape after the excessively bent conductor is stretched, which will cause the cable to bulge. If this happens for a long time, the conductor will break
