Abstract
The utility model is related to a kind of far infrared cold resistant cables for being adapted to high latitude area; including conductor wire core, internal layer protective shell, external insulation layer and the PVC protective layers set gradually from inside to outside; a heat insulation layer is additionally provided in the periphery of the PVC protective layers; uniformly coated with a far infrared coating between the conductor wire core and internal layer protective shell, and a far infrared barrier layer is then uniformly coated between the PVC protective layers and heat insulation layer.The utility model is by adding far infrared coating, this partial heat that cable internal layer copper conductor generates can be converted to far infrared, the stronger far infrared of penetration power can be evenly heated other insulating materials beyond cable internal layer, play better cold-resistant effect, and the far infrared barrier layer set can effectively prevent extra far infrared from discharging to external environment, and the design of heat insulation layer then can effectively resist the invasion and attack of outer low temperature.
Description
Technical field
The utility model is related to field of cable technology, resist cold more particularly to a kind of far infrared for being adapted to high latitude area
Cable.
Background technology
Electric wire is to transmit electricity（Magnetic）Energy, information and the wire product for realizing electromagnetic energy conversion.With tower crane lifting
Exemplified by the cable powered in operation to main power source, which is mainly 3 plus 2 type copper core heavy tape cabtyre cables, and 3 main cores are used for
Ground power supply is transmitted to tower crane control room 400V three phase mains, and 2 cores are for ground power supply to the single-phase controls of tower crane control room 220V
Power delivery processed, cable length and tower crane lifting are highly consistent, generally 60-100 meters.And tower crane is largely severe
It works under environment, such as in high latitude area, weather is very cold, although resistance is more at low ambient temperatures for the copper conductor in cable
It is low, electrical transfer efficiency higher, but long-term low temperature environment can make the performance of cable interior insulation material decline to a great extent, and increase accident hair
Raw probability.In this regard, at present enhancing cable cold tolerance mainstream scheme using cold-resistant high molecular material as in cable
Insulating materials, however, this scheme is due to material performance requirement higher, Material Cost also higher causes cold resistant cable
Remaining high for price, is unfavorable for being widely popularized.
Utility model content
Therefore, for it is above-mentioned the problem of, resist cold electricity the utility model proposes a kind of far infrared for being adapted to high latitude area
Cable.
To realize above-mentioned technical problem, the solution that the utility model is taken is：A kind of high latitude area of being adapted to
Far infrared cold resistant cable, including conductor wire core, internal layer protective shell, external insulation layer and the PVC protections set gradually from inside to outside
Layer, a heat insulation layer is additionally provided in the periphery of the PVC protective layers, between the conductor wire core and internal layer protective shell
It is even to be coated with a far infrared coating, and then uniformly hindered between the PVC protective layers and heat insulation layer coated with a far infrared
Interlayer.
It is further improved to be：The conductor wire core includes annealed copper wire and the interior insulation for being coated on annealed copper wire periphery
Layer.
It is further improved to be：The internal layer protective shell is polyethylene layer.
It is further improved to be：The external insulation layer and inner insulating layer are polytetrafluoroethylene ethylene layer.
It is further improved to be：The thickness of the PVC protective layers is 4.5-9.5mm.
It is further improved to be：The heat insulation layer is asbestos layer.
It is further improved to be：The thickness of the far infrared coating is 1.2-3.0mm.
By using preceding solution, the beneficial effects of the utility model are：Although the resistance of copper conductor is relatively low,
Copper conductor can still generate a little heat during electrical transmission, this partial heat is only capable of rising in cable internal layer in cold environments
To certain anti-cold effect, can not conduct completely to other insulating materials beyond cable internal layer, and the utility model passes through
Far infrared coating is added, this partial heat that cable internal layer copper conductor generates can be converted to far infrared, penetration power is stronger
Far infrared can be evenly heated other insulating materials beyond cable internal layer, play better cold-resistant effect, and set
Far infrared barrier layer can effectively prevent extra far infrared from discharging to external environment, and the design of heat insulation layer can then have
Effect resists the invasion and attack of outer low temperature.
