Secondary wrapping method of cable core to improve insulation performance and wrapping quality of communication cables

Abstract

The invention belongs to the technical field of communication cables and particularly relates to a cable core secondary wrapping method for improving the insulation performance of communication cables and the wrapping quality. When secondary wrapping is performed on a cable formed through primary wrapping of the communication cables, a track type tractor additionally arranged between a wheel tractor and a second flier and a winding wheel of a winding device are used for pulling the cable formed through primary wrapping, power is not input in the wheel tractor, the front traction wheel and the rear traction wheel of the wheel type tractor are driven wheels and neither the front traction wheel nor the rear traction wheel rotate around the longitudinal axis of the wheel type tractor, nor the winding wheel of the winding device rotates around the longitudinal axis of the winding device, during the secondary winding process, the cable cannot be increasingly tightened, the surface of the cable has no fold, the wrapping quality of cable cores and the insulation performance of the communication cables are improved, and the product quality is guaranteed. The cable core secondary wrapping method for improving the insulation performance of the communication cables is applicable to the condition that a communication cable factory utilizes conventional cabling equipment to produce four or more than four super-unit high insulation performance communication cables.

Description

technical field [0001] The invention belongs to the technical field of communication cables, in particular to a secondary wrapping method for a cable core that improves the insulation performance and wrapping quality of a communication cable. Background technique [0002] In order to improve the insulation performance of the communication cable, in the cable production process, the use of multiple windings can solve the leakage of the cable core and improve the insulation performance of the communication cable. However, when the wheel tractor and the take-up device rotate for many times, the cable core becomes tighter and tighter, causing wrinkles on the surface of the cable core, which affects the insulation performance of the cable. If the winding is too tight, it is also easy to break the wire during the process of making the sheath. However, the wheel tractor and the take-up device do not use the rotating method, the wheel tractor cannot play the role of traction, and a...

However, when the wheel tractor and the take-up device rotate for many times, the cable core becomes tighter and tighter, causing wrinkles on the surface of the cable core, which affects the insulation performance of the cable.

If the winding is too tight, it is easy to break the wire during the process of making the sheath

However, the wheel tractor and the take-up device do not use the rotating method, the wheel tractor cannot play the role of traction, and at the same time, the large logarithm cable core has a large drop force, so that the production cannot be completed only by the take-up device for traction
