Heavy-type rubber jacketed flexible cable

Abstract

The invention discloses a heavy-type rubber jacketed flexible cable, comprising insulating wire cores, wherein each insulating wire core is formed by longitudinally arranging tin-plated copper conductors and aluminum alloy conductors in parallel at intervals and then jointly extruding a high-elasticity silicone rubber insulating layer; the two insulating wire cores are closely and transversely arranged in parallel and then are wrapped together with metallized paper or semi-conductive tapes as an inner shielding layer, a copper tape outer shielding layer is woven outside the inner shielding layer, a waterproof film is wrapped outside the copper tape outer shielding layer, a ceramic fiber tape is wrapped outside the waterproof film, a low-smoke halogen-free flame-retardant polyolefin oxygenbarrier layer is extruded outside the ceramic fiber tape, and a rubber outer jacket is sleeved outside the low-smoke halogen-free flame-retardant polyolefin oxygen barrier layer. The heavy-type rubberjacketed flexible cable disclosed by the invention not only has excellent mechanical and physical properties, oil resistance, electrical properties, flame resistance and processing performance, but also has the characteristics of no halogen, low smoke volume and the like.

Description

technical field [0001] The invention relates to the field of cables, in particular to a heavy-duty rubber-sheathed flexible cable. Background technique [0002] At present, with the development of informatization and automation, the intelligence of various mobile appliances is getting higher and higher. [0003] Although the rubber-sheathed cable can withstand large mechanical external forces, intelligent electrical appliances are moving more and more frequently. The existing heavy-duty rubber-sheathed cables cannot meet the requirements in terms of tensile and torsion resistance, fire resistance, and waterproofing. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, a heavy-duty rubber-sheathed flexible cable is provided. [0005] Technical solution: In order to achieve the above object, the present invention provides a heavy-duty rubber-sheathed flexible cable, which includes an insulated core, and the ins...
