Abstract
A metallic shield rubber sheathed flexible cable for a coal cutter comprises three power wire cores and a protective cover covering the three power wire cores. Each power wire core comprises, from inside to outside, a conductor and an insulating layer wrapping on the conductor; and the insulating layer is wrapped by a metallic shielding layer. The metallic shielding layers are arranged so that the fire resistance ability and the antistatic property of the cable are substantially improved and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of coal-winning machine cable, relates in particular to 3.3kv small-power cable.
Background technology
What cable can be subjected to the kindling piece often under mine pounds pressure, extruding, impact, and other mechanical force; add the impact of underground wet environment; present common cable on the market is because tensile strength and tearing toughness are poor; very easily damage; bought potential safety hazard for the operation of coal industry, have much room for improvement.
Moreover existing on the market small-power is with all including a ground connection core in the structure of cable, leak electricity when preventing short circuit, Chinese patent 201020519582.1,201020182380.2,200920188182.4, the 200820160764.7 disclosed electric cable for coal mining machine ground connection core of all guaranteeing replacement for example, though above-mentioned patent all can open the effect that prevents the short circuit electric leakage, but cost of manufacture strengthens, and anti-flammability and antistatic behaviour are not ideal enough.Have much room for improvement.
Summary of the invention
The utility model provides the 3.3kv that a kind of cost of manufacture is low, fire-retardant and antistatic effect is good coal mining machine flexible cable with metallic shielding rubber sleeve for the deficiencies in the prior art.
Key problem in technology of the present utility model is to add the layer of metal screen outside power line core insulation layer, namely played the effect of making ground wire, anti-flammability and antistatic behaviour have greatly been improved again, concrete technical scheme is: a kind of coal mining machine flexible cable with metallic shielding rubber sleeve, formed by three strands of power cores and the outer sheath of parcel power core, the power core is followed successively by from inside to outside conductor and is wrapped in the outer insulating barrier of conductor, it is characterized in that described insulating barrier is wrapped with one and doublely does the metal screen layer that ground wire is used.
As further improvement of the utility model, be filled with marine glue between power core and sheath.Greatly improve shielding by this kind setting, and prevent the conductor short circuit of making moist.
As further improvement of the utility model, described sheath is coated with one deck graphite outward.Arrange by this kind and effectively to prevent the eddy current that produces in the power delivery, prevent conductor temp .-elevating.
The beneficial effects of the utility model: the utility model has greatly improved anti-flammability and the antistatic behaviour of cable, and has saved production cost by metal screen layer is set.
Description of drawings
Fig. 1 is structural representation of the present utility model.
