A kind of cable production process

Abstract

The invention relates to the cable production and processing field, specifically a cable production process. The cable production process comprises the following steps of performing drawbench: preparing raw materials into wire materials of a certain diameter by a drawbench in a drawbench manner; performing stranding: enabling the multiple wire materials to be stranded together to form a cable by astranding machine; performing insulation: spraying the stranded cable surface with insulating paint by painting equipment; sheath forming: sleeving the outer layer of the insulating paint with a layer of insulting protection sleeve; and performing detection: performing test on the transmission performance, the geometric dimensions, flexibility and voltage withstand level of the prepared cable bytesters. In the insulating link of the process, the adopted painting equipment adopts a longitudinally rotating stirring mechanism, so that the solid raw materials at the bottom of a mixed box can bestirred constantly, and the solid raw materials can be fully mixed with liquid raw materials, thereby avoiding aggregation of the solid raw materials at the bottom; and in addition, the stirring blades adopt cambered surface structures, so that the contact areas between the blades and the liquid can be enlarged, the number of times of turning and stirring in each time is increased, and mixing timeis shortened.

Description

technical field [0001] The invention relates to the field of cable production and processing, in particular to a cable production process. Background technique [0002] The insulating coating can form a layer of ceramic coating with high volume resistivity on the surface of the coated object, which can withstand a strong electric field without being broken down. The coating has high mechanical strength and good chemical stability, and is resistant to aging, water, and chemical corrosion; it also has mechanical and thermal shock resistance, and the coating can work continuously at the corresponding working temperature. [0003] In the production process of cables, the insulation coating needs to be sprayed on the outside of the cable by injection molding. However, when the current insulation coating is processed, the stirring method is mainly horizontal rotation, which makes many solid particles still gather at the bottom layer, resulting in solid particles and liquid raw mat...

Problems solved by technology

[0003] In the production process of cables, the insulation coating needs to be sprayed on the outside of the cable by injection molding. However, when the current insulation coating is processed, the stirring method is mainly horizontal rotation, which makes many solid particles still gather at the bottom layer, resulting in solid particles and liquid raw materials. The mixing is uneven and the effect is not good; and after the insulation coating is applied on the outside of the cable, it is necessary to wait for the coating to dry before proceeding to the next step, which is troublesome
