Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-5, metal shielded zonary rubber jacketed flexible cable of coal winning machine, including cable body 1, cable body 1 is by outer shield Set 2 and the control conductor 3 being wrapped in inside oversheath 2 and power wire core 4 form, and control conductor 3 is by the first inner sheath 31 and sets It sets the wire reinforcement 34 at 31 inside center of the first inner sheath to form, the first inner sheath 31 is internally located at wire reinforcement 34 outside surrounding is fixed with the first conductor 33, and the first insulating layer 32 is enclosed on the outside of the first conductor 33, and power wire core 4 is by Two conductors 41 and the second inner sheath 42 for being wrapped in 41 outside of the second conductor form, and the second inner sheath 42 is located on the second conductor 41 Inside be enclosed with second insulating layer 43.

First inner sheath 31 is made of the first semi-conductive cloth tape 311 and fiber braiding layer 312, and the second inner sheath 42 is by second Semi-conductive cloth tape 421 and weaving metallic fibers layer 422 form.

There are six power wire core 4 is arranged altogether, and it is two groups that six power wire cores 4, which are divided to, and every group three about 3 phase of control conductor Mutually symmetrical, there are six the total settings of the first conductor 33, and six the first conductors 33 are distributed in a ring, between adjacent two first conductor 33 Spacing it is equal, oversheath 2 be internally located at the spacing between the power wire core 4 and control conductor 3 of 3 two sides of control conductor be 5mm, Second conductor 41 uses monofilament tinned copper wire, and oversheath 2 uses flame retardant rubber sheath.
