Abstract
The utility model belongs to the technical field of electric wires and relates to a fire-resistant polyvinyl chloride electric wire, wherein more than one mica tape layer as a fire-resistant layer is wound outside of a copper conductor, and a protective layer made of polyvinyl chloride is covered outside of the fire-resistant layer in an extrusion manner. The electric wire has the advantages of flame retardation, fire resistance, fine high temperature performance and low cost.
Description
Technical field
The utility model belongs to electric wire, cable technology field, refers in particular to a kind of fire-resistant polyvinyl chloride (PVC) electric wire.
Background technology
At present, normally at conductor outer wrapping one deck plastic wrapper, plastics have good insulation property for electric wire, cable that we use, but fire protecting performance is poor, when aging circuit, short circuit, overload, cause the electric wire heating and spontaneous combustion easily, initiation fire; In addition, said wires, fireproofing of cable performance are also relatively poor, some markets, residential quarter, skyscraper, public place of entertainment, also this electric wire of employing, cable arranged, but mostly these places are the place that people are movable intensive, if unexpected fire burns out electric wire, cable, can not in time obtain power supply in fire-fighting and the Emergency Power system, consequence will cause irreparable damage.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, again economical low price, can fire-retardant, fire-resistant, resistance to elevated temperatures fire-resistant polyvinyl chloride (PVC) electric wire good, that cost is low.
The purpose of this utility model is achieved in that
Fire-resistant polyvinyl chloride (PVC) electric wire is surrounded with mica tape more than one deck as flame retardant coating outside copper conductor, extrude the protective layer that one deck is made by polyvinyl chloride outside flame retardant coating.
The cross section of above-mentioned copper conductor≤16 square millimeter.
Above-mentioned wrapped mica has two-layer.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model is surrounded with the mica tape flame retardant coating between the sheath that copper conductor and polyvinyl chloride are made, and can reach 750 ℃ to 800 ℃ by fire-retardant, fire-resistant high temperature, even if also be not easy initiation fire when aging circuit, short circuit, overload;
2, the utility model fire resistance is good, still can keep normal operation of regular hour to can be fire-fighting when fire burns, and certain power supply is provided in the urgent power-supply system, can avoid or retrieve the loss that some fire cause.
3, the utility model is simple in structure, and is practical, and fire-proof high-temperature resistant is effective, the convenient use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1:
Fire-resistant polyvinyl chloride (PVC) electric wire is surrounded with mica tape more than one deck as flame retardant coating 2 outside copper conductor 1, extrude the protective layer 3 that one deck is made by polyvinyl chloride outside flame retardant coating 2.
Cross section≤16 of above-mentioned copper conductor 1 square millimeter.
Above-mentioned wrapped mica has two-layer.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection range of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection range of the present utility model.
