Abstract

The invention discloses an oil-resistant water-proof corrosion-resistant double-shielded control cable for a coal mine. The control cable comprises main cable cores, control cable cores, a taping layer, an insulating layer, a shielding layer, a water-proof layer and a protective sleeve. An inner shielding layer is arranged between the taping layer and the insulating layer. The inner shielding layer is formed by wrapping nickel-plated copper aluminum alloy wires around silicone rubber in parallel in a braided mode. A heat insulation layer is arranged between the shielding layer and the water-proof layer in a wrapped mode. A grounded cable core and the control cable cores are wrapped in the heat insulation layer. The protective sleeve is a sheath formed by wrapping steel wires in butyronitrile, and an anti-corrosive agent and an oil-resistant agent are added on the protective sleeve. The cable has good conductivity and is resistant to high temperature, resistant to dragging and bending and resistant to mechanical abrasion, thereby being mainly applied to the fields of coal mines, communication, chemical engineering, petroleum and the like. Besides, the cable has a good shielding effect and excellent corrosion resistance and is waterproof and capable of resisting oil.

Description

technical field [0001] The invention belongs to the field of cables, in particular to an oil-resistant, waterproof, anti-corrosion, double-shielded control cable for coal mines. Background technique [0002] At present, with the rapid development of my country's national economy and the increasing level of science and technology, the growth of cable consumption has been accelerated, and the quality requirements for cables have also been continuously improved. For example, for cables used in coal mines and other fields, due to the special working environment, ordinary cables cannot meet the requirements of use. The actual situation requires that the cables used have higher requirements for insulation, tensile strength, oil and water resistance, wear resistance and flame resistance, shielding performance and corrosion resistance. Only by meeting the requirements can the safety of production in these areas be improved. Contents of the invention [0003] In order to overcome...
