Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0015] Such as figure 1 As shown, the present invention provides a kind of mobile metal shielding monitoring type rubber sheath flexible cable for coal mines,

[0016] It includes three power cores arranged in a triangle. The power cores are the power core conductor 1, the conductor shield 2, the insulation 3 and the insulation shield 4 from the inside to the outside. The inner sheath 7, the monitoring layer 8, the insulating wrapping tape 9 and the outer sheath 10, the filling 5 is provided between the power core and the cable wrapping layer 6, and the inner sheath 7 and the outer sheath 10 are ethylene-octene The conductor shield 2 is extruded from a semi-conductive rubber composed of ethyle...

Abstract

The invention provides a moving metal shielding monitoring rubber jacketed flexible cable for a coal mine. The moving metal shielding monitoring rubber jacketed flexible cable for the coal mine comprises three power cable cores which are arranged in a triangular mode. Each power cable core is sequentially composed of a power cable core conductor, a conductor shield, an insulator and an insulating shield from inside to outside. A cabling taped covering, an inner protection sleeve, a monitoring layer, an insulating taped covering and an outer protection sleeve are sequentially arranged outside each power cable core. Fillings are arranged between the power cable cores and the cabling taped coverings. The inner protection sleeves and the outer protection sleeves are formed by extruding and wrapping ethylene-octylene mixtures. The moving metal shielding monitoring rubber jacketed flexible cable has the performances of being friendly to environment, low in cost, strong in weather fastness and the like.

Description

technical field [0001] The invention relates to a cable, in particular to a mobile metal shielding monitoring type rubber-sheathed flexible cable for coal mines. Background technique [0002] At present, the conductors of mine mobile cables in the coal mining industry are mostly tinned annealed copper conductors with multiple twisted structures, the insulation is composed of ethylene-propylene rubber, and the sheath is chloroprene or chlorinated polyethylene flame-retardant rubber. , but also contains heavy metals such as lead and cadmium, which will produce a large amount of corrosive halogen acid gas when used. In addition, the overall cost of mining mobile cables is high, the tear resistance is poor, and the compatibility and strippability of the shielding layer and the insulating layer are difficult to balance. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art, and provide a mobil...
