Abstract
The utility model discloses a kind of low smoke and zero halogen middle-high voltage power cable, including the cable core set gradually from inside to outside, armor, screen layer and external sheath layer, some lateral isolation rods and longitudinal insulating bar are provided with the cable core, the setting that intersects of the lateral isolation rod and longitudinal insulating bar forms several grid areas, set in the cable core by several conductors, the Surface coating of the conductor has insulating barrier, each conductor is located separately in the insulation fill stratum that filling cable core space in a grid area, is additionally provided with the cable core.The utility model greatly reduces the heat transfer between conductor and conductor, so that in the case of the temperature of respective conductors generation Kelvin effect conductor is drastically elevated, therefore the inside bulk temperature of cable core will not be substantially improved, so as to be effectively guaranteed the temperature environment of cable outer layer, the safety in utilization of cable is improved, the service life of cable is extended.
Description
Technical field
The utility model is related to field of cables, and in particular to a kind of low smoke and zero halogen middle-high voltage power cable.
Background technology
Existing high voltage power cable is mostly stranded as conductor using naked copper or tin-coated copper, during power transmission,
Kelvin effect can occur for high frequency electric, cause the temperature of peripherally located conductor and can drastically raise, it is possible to can damage cable
Outer layer, or even fire is caused, and also conductor can be born against together cable in the presence of by external force in use, so that
The bulk temperature inside the heat transfer of temperature, lifting cable core can be accelerated so that the outer layer of cable is more prone to damage.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, there is provided in a kind of cable core internal structure stabilization, cable core
The low smoke and zero halogen middle-high voltage power cable that portion's temperature can be effectively controlled.
Technical scheme：To achieve the above object, the utility model provides a kind of low smoke and zero halogen middle-high voltage power cable, including
Some lateral isolation rods are provided with cable core, armor, screen layer and the external sheath layer set gradually from inside to outside, the cable core
With longitudinal insulating bar, the setting that intersects of the lateral isolation rod and longitudinal insulating bar forms several grid areas, the cable
In-core is set by several conductors, and the Surface coating of the conductor has insulating barrier, and each conductor is located separately in one
In grid area, the insulation fill stratum in filling cable core space is additionally provided with the cable core.
Design principle of the present utility model is：The setting that intersects of lateral isolation rod and longitudinal insulating bar forms several lattice
Subregion, each conductor is located separately in a grid area, come in contact between conductor and conductor so as to be prevented, horizontal
All possesses fabulous insulated heat function to insulating bar and longitudinal insulating bar, so as to greatly reduce between conductor and conductor
Heat transfer so that in the case of the temperature of respective conductors generation Kelvin effect conductor is drastically elevated, the overall temperature in inside of cable core
Therefore degree will not be substantially improved, so as to be effectively guaranteed the temperature environment of cable outer layer.
Further, the screen layer is crosslinked polyetylene insulated screen layer.
Further, the armor is aluminium strip lock armo layer.
Further, the insulating barrier is insulating oil enamelled coating.
Beneficial effect：Compared with prior art, lateral isolation rod and longitudinal insulating bar intersect setting the utility model
So that the conductor inside cable core will not come in contact each other, lateral isolation rod and longitudinal insulating bar all possess fabulous insulation
Heat insulating function, so as to greatly reduce the heat transfer between conductor and conductor so that occur Kelvin effect in respective conductors and lead
In the case of the temperature of body is drastically elevated, therefore the inside bulk temperature of cable core will not be substantially improved, so as to effectively ensure
The temperature environment of cable outer layer, improves the safety in utilization of cable, extends the service life of cable.
