Abstract

The invention provides a mining signal cable. According to the mining signal cable, each core wire is composed of extruded insulated layers outside a conductor, two or more core wires are hinged, drainage wire sets, cooper strip shielding layer sets, isolating layer sets and braided shielding layer sets are arranged in sequence to form cable core sets, a main cable core is formed by hinging the cable core sets, a water blocking packing layer is arranged in the clearance of the main cable core, and an isolating layer, a drainage wire, a copper strip shielding layer, an inner protective sleeve, a flame resistant layer, a braided shielding layer, a water blocking layer and an outer protective sleeve are arranged outside the main cable core in sequence. The mining signal cable has the properties of being dampproof, waterproof and resistant to fire and resisting electromagnetic waves, and is especially suitable for the signal transmission of various mines with complex work environments.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a mine signal cable. Background technique [0002] Various types of mining in my country have gradually entered into modern development, and various types of explosion-proof electrical appliances and automatic mining equipment have begun to be widely used in mines, making mine signal cables not only to adapt to complex mine environments, but also to meet various electromagnetic interferences. The traditional mining signal cable only considers to resist the electromagnetic wave interference outside the cable, and does not consider the electromagnetic wave interference between different signal unit groups inside the cable during the signal transmission process of the cable. Contents of the invention [0003] The purpose of this invention is to design and produce a new type of cable structure, which is especially suitable for signal transmission in mines with complex wo...
