Production method of oil-resistant, tensile and anti-corrosion flexible cable

Abstract

The invention discloses a production method of an oil-resistant, tensile and anti-corrosion flexible cable, which comprises the following steps: S1, twisting multiple annealed metal wires into a metalconductor; S2, forming an oil-resistant insulating primer layer; S3, coating the outer surface of the metal conductor with an insulator; S4, coating the outside of a cable unit with a braided metal layer; S5, winding a heat insulation wrapping tape outside each braided metal shielded cable line and filling the gap with filler; S6, winding a waterproof rubber tape outside a blank cable; S7, sleeving the waterproof adhesive tape with an outer sheath; and S8, forming a finish paint layer on the surface of the outer sheath. The invention relates to the technical field of cables. By combining primer with finish paint and preventing water through a butyl rubber tape, the cable can be more oil-resistant and anti-corrosion. The tensile performance of the cable is improved by the metal braided layer. Under the condition of maintaining the flexibility, the characteristic of the cable is greatly enhanced, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a production method of an oil-resistant, tensile, anti-corrosion and flexible cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering. Most of them are erected in the air or installed underground or underwater for telecommunications or power transmission. The cable is mainly composed of the following 4 parts. ①Conductive wire core: made of high conductivity material. According to the requirements of cable softness under laying conditions, each wire core may be formed by twisting a single wire or multiple wires. ②Insulation layer: The insulation material used for cables should have high insulation resistance, high breakdown electric field strength, low dielect...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a production method of an oil-resistant, tensile, and anti-corrosion flexible cable, which solves the problem that there is a kind of flexible cable in the existing cable classification, and its processing method is the same as that of commonly used cables. Poor anti-corrosion and oil resistance, poor tensile effect, easy to damage during practical use, and short service life
