Description
Technical field
This utility model patent relates to wisdom energy traffic pair twist shielded communication cable.
Background technology
Along with the development of wisdom traffic system, the requirement that wisdom friendship universal cordage uses environment and performance is more and more higher.Require, on the premise of ensureing cable serviceability, to reduce the insulation thickness of cable and the diameter of conductor as far as possible, improve heatproof, oil resistant, rub resistance, resistance to environmental rating, require that insulant has the environmental friendliness performances such as low-smoke non-halogen flame-retardant simultaneously.Along with the space of the wisdom vehicles is gradually reduced, the structure of cable is more and more compacter, and the work space of core of a cable is more and more less, and signal transmission class cable distance to each other is the least, and existing cable structure can not meet this requirement.
Utility model content
This utility model patent purpose is to provide wisdom energy traffic pair twist shielded communication cable and production technology.
The technical scheme realizing this utility model purpose is: wisdom energy traffic pair twist shielded communication cable, including: cable core, wheat drawstring, drainage thread, screen layer and oversheath；Described cable core, wheat drawstring, screen layer and oversheath set gradually from the inside to the outside, and described drainage thread is arranged in screen layer；Described cable core includes four groups of cores and the filling being filled between core；Described often group core includes the insulated wire cores of two pair twists and is coated on the aluminium-plastic tape outside two insulated wire cores；Described insulated wire cores includes conductor and insulating barrier.
Described conductor and drainage thread are tin-coated copper；Described it is filled to environmental protection flame retardant PP.
Described every conductor and drainage thread are that the copper wire of 0.182mm is the most stranded according to the structural stratification synnema of 1+6+12 by 19 string diameters；Pitch is 16～18mm, and the external diameter of conductor is not more than 0.85mm, and 20 DEG C of D.C. resistances are not more than 38.50 Ω/km.
Described insulating barrier is low smoke and zero halogen crosslinked polyolefin materials, and thickness of insulating layer thinnest point is 0.34mm, and insulating barrier average thickness is 0.4mm；Insulated wire cores external diameter is not more than 1.6mm；Described aluminium-plastic tape aluminum faces outwardly, and rate of putting up is not less than 50%, thickness 0.15mm, width 20mm；After wrapped aluminium-plastic tape, core external diameter is not more than 4.0mm.
Using technique scheme, this utility model patent has the advantages that cable of the present utility model has compact conformation, good bending property, superior electrical property, higher anti-outside electromagnetic interference characteristic, advantage that capacitance is low.
