Abstract
The utility model provides a polytetrafluoroethylene cable film. The polytetrafluoroethylene cable film is characterized in that the upper and lower outer surfaces of the polytetrafluoroethylene cable film are respectively provided with upper and lower densely sintered layer which are formed through high temperature sintering. The roll length of the polytetrafluoroethylene cable film is 50 m to 3000 m, the thickness is 0.03 mm to 0.3 mm, the thickness tolerance is +/-0.003mm to +/- 0.005mm, and the dielectric strength of the polytetrafluoroethylene cable film is higher than 70-80kV/mm. The polytetrafluoroethylene cable film of the utility model can be effectively used as a wire cable insulation layer, the insulation performance of a cable joint can be raised, and the high temperature resistance performance of the cable joint is improved. The polytetrafluoroethylene cable film is suitable for the cable and the insulation layer at the cable joint.
Description
Technical field
The utility model relates to a kind of cable film, particularly relates to a kind of polytetrafluoroethylene cable film.
Background technology
Polytetrafluoroethylene cable film has numerous characteristics because of it than other cable insulations, so be familiar with and use.The advantage of polytetrafluoroethylene cable film is as follows: 1, present employed cable insulation external diameter is big, and easily broken when installing and using or split, have a strong impact on fail safe and useful life that cable uses, and polytetrafluoroethylene cable film has certain pliability and tensile strength more than 15MPa, can effectively address the above problem, thereby improve fail safe and the life-span that cable uses.2, present employed cable insulation is scarcely high temperature resistant, when the weather sweltering heat or cable environment for use temperature is higher and cable conductor transmission current process in a large amount of heat that produces make insulating barrier softening even cause fire easily, and polytetrafluoroethylene cable film is high temperature resistant to 240 ℃, melting temperature is more than 330 ℃, and it is nonflammable, can effectively address the above problem, improve fail safe and useful life that cable uses.3, present employed cable insulation and restrictive coating concentricity are poor, influence the efficiency of transmission of electric current, and are wrapped in around the conductor with polytetrafluoroethylene cable film, can solve the problem of concentricity difference, improve current delivery efficient, cut down the consumption of energy.
But, for too short or other reasons need link together two or two above cables because of length between the cable of cable and the cable, so can produce joint, so and the joint impedance can produce bigger heat greatly, temperature is higher.Yet, though employed common polytetrafluoroethylene cable film has temperature tolerance preferably at present, during in the face of 360 ℃ of high temperature; be sintered rapidly; be transparence, and the dielectric strength of common polytetrafluoroethylene cable film does not reach the fail safe of protective wire cable joint only about 50kV/mm thus.
Summary of the invention
The purpose of this utility model is that a kind of improved polytetrafluoroethylene cable film will be provided, and it not only can be effective as the wire cable insulating layer, and can also improve insulating properties and more high temperature resistant in online cable joint place.
Solution of the present utility model to achieve the above object is: polytetrafluoroethylene cable film of the present utility model comprises a polytetrafluoroethylene cable film, the upper and lower outer surface of described polytetrafluoroethylene cable film is made as the upper and lower closely knit sinter layer that forms through high temperature sintering respectively, the volume of described polytetrafluoroethylene cable film is long to be 50m-3000m, thickness is 0.03-0.3mm, thickness deviation is ± 0.003mm-0.005mm that the dielectric strength of described polytetrafluoroethylene cable film reaches more than the 70-80kV/mm.
The volume of described polytetrafluoroethylene cable film is long to be 50m-1000m, and thickness deviation is ± 0.003mm.
The volume of described polytetrafluoroethylene cable film is long to be 1000m-2000m, and thickness deviation is ± 0.004mm.
The volume of described polytetrafluoroethylene cable film is long to be 2000m-3000m, and thickness deviation is ± 0.005mm.
Polytetrafluoroethylene cable film provided by the utility model, and taked to be made as the upper and lower closely knit sinter layer that forms through high temperature sintering respectively at the upper and lower outer surface of described polytetrafluoroethylene cable film.
When polytetrafluoroethylene cable film of the present utility model is wrapped in cable and cable connector place, can carry out the good insulation performance protection to cable conductors.Because on the polytetrafluoroethylene cable film of the present utility model; following outer surface in film forming procedure by double sintering; the surface forms closely knit sinter layer to improve insulating properties; and inside is not sintered and is still filamentary structure; so under 360 ℃ of hot conditionss; less and the light of the deformation quantity of film itself still can not therefrom see through; thereby reach opaque effect; and it all has excellent dielectric properties and electrical stability in very wide frequency range; dielectric strength reaches and can arrive more than the 70-80kV/mm; thus; effectively protect cable, protected cable connector especially better.
Polytetrafluoroethylene cable film of the present utility model is applicable to the insulating barrier of cable and cable connector.
