Abstract
The invention relates to a water-resisting flame-retardant cable comprising a copper conductor. The copper conductor is externally and sequentially extruded with an insulation layer and a shielding layer, and thus a cable core is formed. The cable core is externally and sequentially provided with a water-proof layer and a flame-retardant outer sheath. The water-proof layer is a three-layer structure, namely a semiconductive water-resisting band, a water-resisting buffer band and a metal braided band from inside out in sequence. The outer sheath is a polyvinyl chloride outer sheath. The water-resisting flame-retardant cable has the advantages of being good in flexibility, and excellent in electrical performance, flame retardant performance, waterproofing performance and physical and mechanical performances, strong in environment adaptation capability, safe and environment-friendly, low in production cost, and capable of being used for a long time.
Description
Technical field
The present invention relates to a kind of special cable, relate in particular to a kind of flame retardant cable that blocks water.
Background technology
Develop rapidly along with China's industry, plastic insulated cable constantly increases in the industrial scope of application and consumption, common plastics insulated cable anti-flammability is poor, add after fire retardant, electrical insulating property reduces, during burning, produce a large amount of poisonous and harmful smog, environment, equipment and personnel's life is had to very big harm.
Summary of the invention
The present invention provides a kind of simple in structure, good, anti abrasive flame retardant cable that blocks water of water proof fire retardant performance in order to overcome the above problems.
Technical scheme of the present invention is: comprise a copper conductor, extruded insulation layer and screen form cable core to described copper conductor successively outward, described cable core is provided with watertight composition and fire-retardant oversheath outward successively, described watertight composition is three-decker, is followed successively by from the inside to the outside semiconductive waterstop, buffer strip and metallic braid block water; Described oversheath is polyvinyl chloride oversheath.
The present invention has good flexibility, excellent electrical properties, fire resistance, water resistance and physical and mechanical properties, and accommodative ability of environment is strong, and safety and environmental protection, production cost are low, can use for a long time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is conductor, the 2nd, and insulating barrier, the 3rd, screen, the 4th, semiconductive waterstop, the 5th, the buffer strip that blocks water, the 6th, metallic braid, the 7th, oversheath.
Embodiment
A kind of flame retardant cable that blocks water, comprise a copper conductor 1, the described outer extruded insulation layer 2 successively of copper conductor 1 and screen 3 form cable core, described cable core is provided with watertight composition and fire-retardant oversheath 7 outward successively, described watertight composition is three-decker, is followed successively by from the inside to the outside semiconductive waterstop 4, buffer strip 5 and metallic braid 6 block water; Described oversheath 7 is polyvinyl chloride oversheath 7.
