Mobile metal shielding monitoring wrapping braiding reinforced rubber jacketed flexible cable for coal mine

Abstract

The invention, which belongs to the cable field, discloses a mobile metal shielding monitoring wrapping braiding reinforced rubber jacketed flexible cable for a coal mine, comprising a power wire core conductor, a grounding detection wire conductor and a ground wire conductor. A power wire core conductor shielding layer, a power wire core insulating layer and a power wire core insulating shielding layer are sequentially arranged on the outer side of the power wire core conductor from inside to outside, a grounding detection wire conductor insulating layer is arranged on the outer side of the grounding detection wire conductor, and the power wire core conductor, the grounding detection wire conductor and the ground wire conductor are all arranged on the inner side of the inner sheath. A monitoring layer, a first reinforcing layer, a second reinforcing layer and an outer sheath are sequentially arranged on the outer side of the inner sheath from inside to outside, rhombic heat insulation cavities are formed in the second reinforcing layer, and communication cavities are formed between any adjacent rhombic heat insulation cavities.The heat insulation and the crack resistance effect of the cable are increased by setting the second reinforcing layer, and the use stability of the cable is ensured.

Description

technical field [0001] The invention relates to the field of electric cables, in particular to a flexible metal sheathed flexible cable with surrounding braiding and braiding, which is used in coal mines for mobile metal shielding monitoring. Background technique [0002] Coal is the main energy source in our country and is closely related to economic construction and people's daily life. In order to ensure the energy supply and maintain the high-speed development of economic construction, the mining volume of coal in my country is growing at a rate of more than 8% every year. Mine rubber sheathed cables are an indispensable supporting product for the coal industry, and are known as the "vessels" and "nerves" of the coal industry. With the continuous advancement of mining technology, coal mines have higher and higher requirements for cables. [0003] With the improvement of the degree of mechanization of coal mining enterprises, the demand for various mining cables in the ...
