Abstract
The invention discloses a waterproof flame-retardant cable which comprises a cable core, a shielding layer, an insulating layer, a waterproof layer, a flame-retardant layer and a sheath layer, wherein the shielding layer, the insulating layer, the waterproof layer, the flame-retardant layer and the sheath layer are sequentially arranged on the periphery of the cable core from inside to outside. The cable core is formed by intertwisting three conductors, and gaps between the conductors are filled with waterproof materials. The sheath layer comprises a metal sheath and a non-metal sheath, and the non-metal sheath wraps the metal sheath. When the waterproof flame-retardant cable is used, the waterproof layer and the flame-retardant layer can reduce damage to the cable by water and blasting in a severe environment; moreover, due to the fact that the gaps between the conductors are filled with the waterproof materials, the damage to the cable by the water can be further weakened, a part of force can be absorbed under the condition that the cable is bent and twisted repeatedly by external force, and insulation damage caused to the cable by long-term dragging and grinding is avoided; the metal sheath can effectively prevent the cable from being chemically corroded by the environment.
Description
Technical field
The present invention relates to technical field of electric wires and cables, relate in particular to a kind of flame retardant cable that blocks water.
Background technology
Cable is widely used in, in colliery, locomotive, illumination and daily life application, along with scientific and technological development, transmission speed and the transmission security of cable being had higher requirement.
Existing cable is generally three cores or the stranded rear establishment stranding of multicore.Under the inferior rugged environment of coal mine, the nocuity materials such as cable Long Term Contact silt, sewage, greasy dirt, easily damage, if can't be arrived by work on hand personnel or monitoring of equipment in time when damaging appears in cable, be easy to cause the damage of equipment, even cause casualties.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes a kind of flame retardant cable that blocks water, be applicable to the various places that have sewage, oil stain and possibility explosion.
A kind of flame retardant cable that blocks water that the present invention proposes, comprise core and be located at screen, insulating barrier, water blocking layer, flame-retardant layer and the restrictive coating of described core periphery, described restrictive coating is positioned at outermost layer, and described screen, insulating barrier, water blocking layer and flame-retardant layer arrange successively from inside to outside.
Further, described core is by three bursts of stranded forming of conductor.
Preferably, the gap-fill of described conductor has material water-proof material.
Preferably, the material of described conductor is copper.
Preferably, described screen adopts the crosslinked material of semiconductor.
Preferably, the mixture compressing tablet that described insulating barrier is polyethylene base-material, crosslinking agent and space charge inhibitor forms.
Preferably, the mixture compressing tablet that described flame-retardant layer is acetate ethylene copolymer, blowing agent, fire retardant and polyolefin elastomer forms.
Further, described restrictive coating comprises metallic sheath and non metallic sheath, and described non metallic sheath coats described metallic sheath.
Preferably, described metallic sheath is stainless steel sleeve.
Preferably, described non metallic sheath is fire-retardant PE.
In the present invention, the setting of water blocking layer and flame-retardant layer can reduce water and explosion under adverse circumstances cable is caused to damage, and at the conductor gap-fill, material water-proof material is arranged, not only can further weaken the destruction of water to cable, and in the situation that be subject to external force alternating bending and torsion, can absorb a part of power, avoid because pulling for a long time, roll the insulation harm to cable, metallic sheath can effectively prevent the chemical corrosion of environment to cable.
