Technical Field
The utility model relates to the technical field of cables, especially, relate to a high temperature resistant power cable.
Background
The power cable is used for transmitting and distributing electric energy, is commonly used for urban underground power grids, power station leading-out lines, power supply inside industrial and mining enterprises and transmission lines under river-crossing seawater, is gradually increased in proportion in the power line, is a cable product used for transmitting and distributing high-power electric energy in a trunk line of a power system, and comprises various insulated power cables with voltage grades of 1-500KV and above.
Most of the existing heat insulation cables are heat insulation through the arranged heat insulation layer, so that the high temperature resistance is limited, and the practicability is not strong.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcomings that the heat insulation layer only through setting is used for heat insulation and the like in the prior art, and providing a high temperature resistant power cable.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a high temperature resistant power cable, includes the sinle silk, the sinle silk is become by the transposition of multiunit cable, the outside cover of sinle silk is equipped with around the covering, has the filling layer around packing between covering and the sinle silk, the outside cover around the covering is equipped with the shielding layer, the outside circumference distribution of shielding layer has the support, the one end that the shielding layer was kept away from to the support is provided with the cover and establishes the insulating layer in the shielding layer outside, the cavity is constituteed with shielding layer and adjacent two sets of supports to the insulating layer, the shielding layer sets up and is provided with the ceramic fibre insulating layer on the inside terminal surface of cavity, the outside parcel of insulating layer has the oversheath.
Preferably, the filling layer is formed by mixing asbestos particles and glass fiber yarns.
Preferably, the outer surface of the outer sheath is sprayed with acrylic resin.
Preferably, the heat insulation layer is an asbestos heat insulation layer.
Preferably, the interior of the cavity is filled with an inert gas.
Preferably, the inert gas is argon or helium.
The utility model provides a pair of high temperature resistant power cable, beneficial effect lies in: the utility model discloses a insulating layer that sets up, the cavity that forms between shielding layer and the support plays thermal-insulated effect, thereby the high temperature resistance performance of this cable has been strengthened, the acrylic resin of setting is used for reflecting away the light of the surface of oversheath, thereby reduce the heating capacity of oversheath, strengthen high temperature resistance, and the inside packing through insulating layer and cavity has inert gas, inert gas is for the air, the big and coefficient of heat conductivity of density is little, thereby reduce gaseous heat conductivity, thereby further ensured the high temperature resistance ability of this cable, this cable reasonable in design, and high temperature resistance performance is better, be worth enterprise's production and to social popularization.
