the utility model provides a mining control cable of high performance environment-friendly, includes the cable body, the cable body includes by outer protective sheath, rubber layer, buffer layer and a plurality of cable cores that set gradually to interior, it is provided with the filling layer to fill between buffer layer and the cable core, the inside of cable core has set gradually sinle silk, insulating layer, shielding layer and fire-retardant layer from interior to exterior.

Further: and a wrapping layer is also arranged between the protective outer skin and the rubber layer.

Further: the shielding layer is a copper strip shielding layer.

Further: the insulating layer is a radiation cross-linked polyethylene insulating layer.

Further: the flame-retardant layer is a halogen-free glass fiber tape double-layer wrapping.

Further: the outer circumference of the protective outer skin is provided with a plurality of groups of waterproof antennae which are trapezoidal bulges.

Compared with the prior art, the utility model has the beneficial effects that:

1. the cable adopts halogen-free non-toxic environment-friendly materials, so that the environment-friendly characteristic of the cable is ensured, the arrangement of the copper wire braided sub-shield is more environment-friendly, harmful gas cannot be generated even if the cable is burnt, and the electrical shielding characteristic of the control cable is improved.

2. The fire-retardant layer in the sinle silk outside and insulating layer can play fire prevention and insulating characteristic, have effectively protected the sinle silk, and rubber layer and buffer layer possess certain shock attenuation buffer capacity, and when the cable atress, can absorb partial force, reduced the power of conducting on the sinle silk, effectively protected the sinle silk, the protection is effectual, and the practicality is good.

In the figure: 1. a cable body; 2. waterproof antenna; 3. a protective sheath; 4. wrapping a covering; 5. a rubber layer; 6. a buffer layer; 7. a filling layer; 8. a cable core; 9. a flame retardant layer; 10. a shielding layer; 11. an insulating layer; 12. and a wire core.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

referring to fig. 1, the present invention provides a technical solution: the utility model provides a mining control cable of high performance environment-friendly, including cable body 1, cable body 1 includes by outer protection crust 3 to interior setting gradually, rubber layer 5, buffer layer 6 and a plurality of cable core 8 of group, it is provided with filling layer 7 to fill between buffer layer 6 and the cable core 8, the inside of cable core 8 has set gradually sinle silk 12 from interior to exterior, insulating layer 11, shielding layer 10 and fire-retardant layer 9, protection crust 3 adopts good fire prevention thermal-insulated material, can play protection and the fire prevention effect to control cable, make protection crust 3 when receiving flame, can not melt into and produce the smoke and dust, the pollution that control cable caused to the environment has been prevented, rubber layer 5 and buffer layer 6 possess the ability of shock attenuation buffering, can reduce the power of conducting to sinle silk 12, effectively protected sinle silk 12, fire-retardant layer 9 can play the effect of isolated fire source, insulating layer 11 has improved the heat-resistant firing of product, Aging resistance, flame retardancy, insulating properties and electrical properties, the shielding layer 10 has electrical shielding properties.
