Abstract
The invention discloses a variable frequency cable which comprises main lines, a filling layer, a flame-retardant non-woven fabric band warping layer, a shielding layer and a jacket. The main lines are sequentially coated with the filling layer, the flame-retardant non-woven fabric band warping layer, the shielding layer and the jacket. Null lines are squeezed by and coated with the filling layer. Both the main lines and the null lines are divided into three groups. The circumferences of the main lines are tangent in pairs. The circumferences of the null lines are tangent to the two adjacent main lines. Both the main lines and the null lines are composed of center inner conductors and insulation layers. The variable frequency cable is good in electric conductivity, resistant to dragging and winding operation, not prone to be broken, resistant to fire and high temperature, capable of being mainly applied to the fields of power generation, metallurgy, chemical engineering and petroleum and the like, high in shielding performance, and capable of preventing electromagnetic waves from being transmitted outside and serving as a short-circuit current channel.
Description
Technical field
The invention belongs to field of cables, particularly relate to a kind of frequency-changing cable.
Background technology
At present, along with the continuous increase of cable consumption, high requirement is also proposed to the quality of cable.General cable mostly is common drum cable, though have the performances such as certain resistance to towing, resistance to winding, bad to harmonic suppression effect.Meanwhile, common frequency-changing cable generally adopt proof copper-wire braided shield, copper wire be wound around shielding or the wrapped shielding of copper strips, shielding rejection coefficient the highest about 85%, and screen cannot meet simultaneously suppression electromagnetic wave externally launch the effect with short circuit current passage.
As long as meet the requirements, the actual service condition of cable just can be met.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one and both there is the performances such as resistance to towing, resistance to winding, also possess and suppress electromagnetic wave externally to launch the frequency-changing cable with the advantage such as short circuit current channeling.
The present invention takes following technical scheme to realize: a kind of frequency-changing cable, it comprises main line and is wrapped in packed layer, fire retardant nonwoven fabric belts lapping layer, screen, the sheath outside main line successively, described packed layer inside extrudes zero line, described main line, described zero line are three groups, described main line circumference is circumscribed between two, described zero line circumference and adjacent two described main line circumference circumscribed, described main line and described zero line are all made up of central inner conductor and insulating barrier, and described insulating barrier adopts import extraordinary butyronitrile compound material extrusion molding to be shaped.
Preferably, described main line color is respectively red, green, yellow.
Preferably, described inner wire is that employing 99.9999% anaerobic is annealed ultra-fine soft copper tow strand, produces by the special soft copper conductor structure of standard GB/T3956-2008 the 6th kind.
Preferably, described screen is by 99.9999% zinc-plated high density anaerobic soft copper silk, forms according to more than count >=90% braiding.
The present invention has following beneficial effect in sum: this kind of cable applications is extensive, conduct electricity very well, resistance to towing, resistance to winding, anti-broken string, fire-proof high-temperature resistant, be mainly used in the fields such as generating, metallurgy, chemical petroleum, waterproof oil resistant, endurance, shielding properties is high simultaneously, both play the effect suppressing electromagnetic wave externally to be launched, can be used as again the passage of short circuit current, reduce operation troubles.
