Abstract
The utility model discloses a cable, in particular a shielding type electrical power cable, which comprises a conductor core, a crosslinkable polyethylene insulation course, a low dielectric constant padding, a heat resistance PVC protecting sleeve, and a cable belting. The utility model is characterized in that a two way stretch polypropylene insulation course is arranged outside of the cable belting; a winding type fourth core conductor is arranged outside of the polypropylene insulation course; a shielding belting is arranged outside of the winding type fourth core conductor; an extrusion type insulation course is arranged outside of the shielding belting; a metal shielding course is arranged outside of the extrusion type insulation course ; and two way stretch polypropylene insulation course is arranged outside of the metal shielding course. The utility model provides an electrical power cable with strong anti jamming and excellent shielding effect.
Description
Technical field:
The utility model relates to a kind of cable, especially a kind of shield type power cable.
Background technology:
Present stage, power cable mainly was the product that meets State Standard of the People's Republic of China GB12706 regulation, and standard is not stipulated the shield type power cable.
In addition for satisfying the requirement that power cable is applicable to the place of shielding requirements, indivedual manufacturer production the power cable of the wrapped type of a kind of copper strips, its structure be on common power cable basis, the rich outward one deck copper strips that wraps of cable core.This kind power cable can play certain shielding action to the electromagnetic interference in the certain frequency, but its shield effectiveness is very poor under high frequency, and power cable screen under the zero sequence operating state can produce induced current, and surrounding space is produced electromagnetic radiation.Can not be applied to the place higher to shielding requirements.
Summary of the invention:
The utility model provides the power cable that a kind of antijamming capability is strong, shield effectiveness is good.The utility model comprises conductor thread core, crosslinkable polyethylene insulating barrier, low-k filler, heat-resistant polyvinyl chloride sheath, cable tie, it is characterized in that: the outside of described cable tie is the Biaxially oriented polypropylene separator, the Biaxially oriented polypropylene separator is outward a winding-type four-core conductor, winding-type four-core conductor is outward the shielding band, the shielding band is outward the extrusion type separator, the extrusion type separator is outward a metal screen layer, and the outside of metal screen layer is the Biaxially oriented polypropylene separator.
The utility model is characterized in that: conductor thread core adopts the stranded structure of pressing of multicore.
The utility model is characterized in that: winding-type four-core conductor adopts double braid or metal tape to add the combined knitting of copper wire, and its count and braiding angle can be adjusted.
The utility model is characterized in that: in winding-type four-core conductor the Biaxially oriented polypropylene separator is set, shielding band and extrusion type separator are set outside winding-type four-core conductor.
Accompanying drawing and drawing explanation:
