Obstruction is not will produce, it is ensured that cable steady operation in the case where high temperature has disturbance state.
To achieve the goals above, the technical solution adopted in the utility model is：A kind of self-rolling high-temperature shielding wave prevention sleeve,
Include separation layer, nickel plating soft copper silk woven shield and high temperature resistance protective layer successively from the inside to the outside, the separation layer uses poly- four
Fluoroethylene film, the high temperature resistance protective layer are prepared by heat-resisting material.
The woven shield count is not less than 85%.
The high temperature resistance protective layer is woven by meta-aromatic poly- phthalein amine fiber Nomex and polyether-ether-ketone resin PEEK
Fire retardant, count be not less than 95%.
The high-temperature shielding wave prevention sleeve has from after knitting forming from volume property, can form cylindrical shape from volume, be adapted to outside cable
Shape, set need not apply additional pressure again when protecting cable.
The beneficial effects of the utility model：
1. the separation layer of the utility model uses polytetrafluoroethylene film in the case where temperature and frequency are widely varied,
Its change in dielectric constant is small；And volume resistivity will not change long-time is impregnated in water, stability is better than it
His insulating materials；Its fabulous release performance and thermal stability not only enable it to be used continuously at 260 DEG C or more, while can be with
Higher temperature is born in a short time.
2. the woven shield of the utility model is woven using nickel plating soft copper silk, count is not less than 85%, has pole
Good corrosion resistance and excellent mechanical performance, while nickel coating can reduce the high-frequency loss in frequency applications, not only play screen
The effect covered, and the bending softness of wave prevention sleeve is substantially increased, while it being effectively protected the damage of cable, improve electricity
The service life of cable.
3. the high temperature resistance protective layer of the utility model is by the poly- phthalein amine fiber Nomex of meta-aromatic and polyether-ether-ketone resin
Fire retardant made of PEEK braidings, count is not less than 95%, material novel environment friendly, heat-resisting, fire-retardant, chemicals-resistant,
Hydrolysis, wear-resisting, corrosion-resistant, radiation resistance, satisfactory mechanical property, fracture strength is high, and elongation is larger, soft, under high temperature
Not softening, does not melt, smokescope is low when burning, and calorific value is low, wash resistant, keeps good through repeatedly washing flame retardant property,
There is preferable dimensional stability, while also substantially increasing the bending softness of wave prevention sleeve, not in cable bend or winding
It will produce obstruction, it is ensured that cable steady operation in the case where high temperature has disturbance state.

Specific implementation mode
Below by way of specific implementation mode, and in conjunction with attached drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of self-rolling high-temperature shielding wave prevention sleeve includes separation layer 1, nickel plating successively from the inside to the outside
Soft copper silk woven shield 2 and high temperature resistance protective layer 3, separation layer 1 use polytetrafluoroethylene film, the volume of nickel plating soft copper silk braiding
It knits shielded layer count and is not less than 85%, high temperature resistance protective layer is by the poly- phthalein amine fiber Nomex of meta-aromatic and polyether-ether-ketone
Fire retardant made of resin PEEK braidings, count are not less than 95%.The high-temperature shielding wave prevention sleeve from after knitting forming from
Volume forms cylindrical shape, is adapted to cable profile, need not apply additional pressure again when set protects cable.
In specific implementation, corresponding structure setting and material selection are respectively：
Using polytetrafluoroethylene film in the case where temperature and frequency are widely varied, dielectric constant becomes separation layer 1
Change small；And volume resistivity will not change long-time is impregnated in water, stability is better than other insulating materials；Its
