An intelligent low-smoke halogen-free flame-retardant and mechanical-impact-resistant cable for shearer

Abstract

The invention discloses an intelligent low-smoke, halogen-free, flame-retardant and mechanical shock-resistant cable for a coal mining machine. The cable body is composed of a cable core and a coating part coated outside the cable core. The control wire core, three reinforced wire cores, a cable core bracket and a group of optical transmission units are composed. The power wire core is composed of the power wire core conductor and the power wire core insulation extruded on the surface of the power wire core conductor from the inside to the outside. layer and the power core conductor shielding layer; the control core is composed of the control core conductor and the control core insulation layer, the ground core conductor and the semi-conductive shielding layer that are coated on the surface of the control core conductor in turn. The inner part includes the cable inner sheath and the cable outer sheath which are coated on the outer surface of the cable core from the inside to the outside. It can transmit optical signals, and also improves the service life of the cable moving underground. The cable can move freely with the shearer, front, back, left, and right.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an intelligent low-smoke, halogen-free, flame-retardant and mechanical-impact-resistant cable for coal shearers. Background technique [0002] Coal is one of the important energy sources in my country. With the continuous development of my country's economic construction, the demand for electricity is increasing, and the consumption of coal is also increasing. Coal is a kind of mineral energy that exists in nature. There are large reserves in my country, especially in Xinjiang. , Inner Mongolia and Shanxi are particularly rich in coal resources. [0003] It is a mineral resource in nature, buried deep underground. Before liberation, we used manual mining, but now my country's coal mining industry has all used shearers for mining. With the development of science and technology, frequency conversion technology has become more and more widely used in the field of coal mines. Since t...
