Description
Technical field
The present invention relates to a kind of cable more particularly to a kind of low-smoke fireproof cables.
Background technology
Cable is by the cable core formed including conductor, insulating layer, shielded layer, inner sheath, the compositions such as armor and oversheath, tool
There are excellent electric property, physical mechanical property, chemical stability, therefore, this cable widely to be used, the cable is suitable
For large-scale coal mining machine equipment.In these occasions because of environment characteristics, most of cable need to be subjected to being frequently bended, spoil and
Coal cinder punching is pounded, various machinery scraping collisions and extruding or even artificial damage.
Invention content
The present invention provides compact-sized one kind, fire resistant flame retardant, good heat-insulation effect, insulation effect in order to solve problem above
Good, safety and environmental protection, the anti abrasive low-smoke fireproof cable of bend-resistance.
The technical scheme is that：The cable includes four cores, and the core includes conductor, is arranged and leading
External insulating layer, the thermal insulation layer being arranged outside insulating layer, the shielded layer being arranged outside thermal insulation layer and it is arranged outside shielded layer
Inner sheath, the insulating layer are Ceramic silicon rubber insulating layer, and the inner sheath is halogen-free flameproof inner sheath, the screen
It is wrinkle aluminium pack arrangement to cover layer, and described four cores extrude twining package tape and constitute cable core jointly, and fire resisting is arranged outside the cable core
Mica tape, the fire-resistant isinglass belt are arranged iron wire and weave armor, be provided with outside iron wire braiding armor oxygen barrier outside
Layer, the oxygen barrier layer are provided with fire-retardant oversheath outside.
Each core both sides are respectively equipped with load-bearing component, and the load-bearing component is to be twisted bundles of steel wire rope.
The cable conductor is equipped with strengthening core.
Structure of the invention is compact, fire resistant flame retardant, good heat-insulation effect, insulation effect is good, safety and environmental protection, bend-resistance is wear-resistant.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
1 is conductor in figure, and 2 be insulating layer, and 3 be thermal insulation layer, and 4 be shielded layer, and 5 be inner sheath, and 6 be fire-resistant isinglass belt, and 7 are
