Cleaning-type oil-resistant cable

Abstract

The invention belongs to the technical field of electrical wire and cable production processes, and particularly relates to a cleaning-type oil-resistant cable. Conductors (1) are copper conductors, the structures of the conductors adopt a first type or a second type, a cross-linked polyethylene insulating layer (2) is extruded on the conductors (1) respectively by applying a warm water cross-linking technology to serve as a cable core, an inner lining layer (3) is arranged outside the cable core, an armor layer (4) is armored by back-twist type galvanized fine steel wires, aluminum-plastic composite tapes are longitudinally coated and welded outside the armor layer (4) to form a water and tide blocking layer (5), and a flame-retardant jacket layer (6) made of a butyronitrile material is arranged at the outermost layer. With a double-layer co-extrusion mode to extrude, the arrangement of the high-strength water and tide blocking layer capable of longitudinally preventing tension in the overall cable and a process of double-layer co-extrusion protection layers, the cleaning-type oil-resistant cable has not only very strong resistance to abrasion and oil, but also better resistance to cleaning, thereby the quality stability of the oil-resistant cable is improved and a new technical field is developed for the development of the cleaning-type oil-resistant cable.

Description

technical field [0001] The invention relates to a clean oil-resistant special cable with a rated voltage of 0.6 / 1kV and below, which belongs to the technical field of electric wires and cables. Background technique [0002] The existing oil-resistant cable production process is simple, and the mechanical performance indicators are not high. The single sheath material and extrusion process make it poor in coating, resulting in reduced shrinkage. At the same time, it is not resistant to corrosion in the laying site environment and has low oil resistance. , The service life of the cable is short. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, a clean oil-resistant cable with better oil resistance and cleaning resistance is provided. [0004] In order to realize the purpose of the present invention, the following technical scheme is now used: a clean type oil-resistant cable, the conductor (1) is a copper conductor, the structure of...
