Description
Technical field
The utility model is related to a kind of low temperature resistant cracking resistance preventing ultraviolet direct current cables, belong to field of cable technology.
Background technology
In wind-power electricity generation, the use occasion of rail traffic, it is desirable that cable has excellent low temperature resistant, cracking resistance, UV resistance
The performances such as light, while should have lower dielectric loss and conductor losses, the working field strength of higher current-carrying capacity and insulation；
And existing cable tends not to be provided simultaneously with the above cable, it is therefore desirable to be improved.
Utility model content
The utility model fully meets wind-power electricity generation, track in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of reasonable for structure
The low temperature resistant cracking resistance preventing ultraviolet direct current cables of the special dimensions requirement such as traffic.
The technical solution adopted in the utility model is thus：The utility model includes cable core, and the cable core includes conductor
（1）, the conductor（1）Extrude organosilane crosslinked polyethylene insulation layer outside（2）；
Wrapped high strength non-woven fabric outside the cable core（3）, the high strength non-woven fabric（3）Peripheral hardware polyethylene inner sheath（4）,
The polyethylene inner sheath（4）Peripheral hardware metal armor layers（5）, the metal armor layers（5）Outside peripheral hardware halogen-free flame-retardant polyethylene
Sheath（6）.
The conductor（1）The structure type of metal is not plated using circular gold-plated category or.
Rounding is filled using polypropylene between cable core.
The polyethylene inner sheath（4）Peripheral hardware galvanized steel strip metal armor layers（5）.
The conductor（1）Using high-quality oxygen-free copper.
The utility model has the advantages that：The cable of the utility model has excellent low temperature resistant, anti-available light aging, resistance to
Cold, insolation proof, humidity resistance, the characteristics such as service life length, halogen-free environmental are widely used in the spies such as wind-power electricity generation, rail traffic
The field very required.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
1 it is conductor in figure, 2 be organosilane crosslinked polyethylene insulation layer, 3 be high strength non-woven fabric, 4 is polyethylene inner sheath, 5
It is halogen-free flame-retardant polyethylene outer sheath for metal armor layers, 6.
Specific implementation mode
The utility model includes cable core, and the cable core includes conductor 1, and it is exhausted to extrude organosilane crosslinked polyethylene outside the conductor 1
Edge layer 2；
Wrapped high strength non-woven fabric 3 outside the cable core, 3 peripheral hardware polyethylene inner sheath 4 of the high strength non-woven fabric are described poly-
4 peripheral hardware metal armor layers 5 of ethylene inner sheath, 5 peripheral hardware halogen-free flame-retardant polyethylene outer sheath 6 of the metal armor layers.
The conductor 1 uses circular gold-plated category or does not plate the structure type of metal.
Rounding is filled using polypropylene between cable core.
4 peripheral hardware galvanized steel strip metal armor layers 5 of the polyethylene inner sheath.
The conductor 1 uses high-quality oxygen-free copper.
The utility model can be circular gold-plated using the 2nd kind of conductor 1, conductor 1 that GB/T 3956-2008 are required is met
Belong to or do not plate the structure of metal；1 surface of conductor extrudes good organosilane crosslinked polyethylene insulation layer 2, and when stranding uses polypropylene
Rounding is filled, and using high strength non-woven fabric 3 around rounded package, inner sheath 4 is using the poly- second with cold-resistant and waterproof and dampproof function
Alkene material, the wrapped galvanized steel strip metal armor layers 5 of rear screw prevent mechanical external force Damage to insulation body, oversheath 6 from using halogen-free type
Flame retardant type polythene material, this material also has halogen-free environmental, low temperature resistant anti-opens in addition to most basic flame retardant property
Strong ultraviolet light is split and resisted, there are stronger ageing properties, meets the requirement of this product open air laying, ensure that product
Service life.
