Description
Technical field
It the utility model is related to a kind of cable, and in particular to the wear-resisting cold-proof novel cable of outdoor.
Background technology
High-speed data transmission cable of the prior art, it can only typically use at normal temperatures, and transmission cable is flexible
Property is not strong, easily by the use under high temperature or low temperature environment and other mal-conditions.In addition, in general high-speed transfer cable
In, the material of filling is few, makes the insufficient strength of cable good, is easily influenceed by ice and snow weather, and the construction of cable is unstable, and data pass
Movement Capabilities are poor.Especially under the larger mal-condition of day and night temperature, cable had both needed higher radiation hardness heat resistance
Can, while to have good resistance to frost.
Utility model content
Technical problem to be solved in the utility model be traditional aerial cable intensity and resistance to frost comparatively
Weakness, under conditions of day and night temperature changes greatly, the construction of cable is unstable, and data transmission capabilities difference is, and it is an object of the present invention to provide family
The wear-resisting cold-proof novel cable of external application, aerial cable resistance to frost and intensity are improved, so as to ensure electric power signal normal transmission.
The utility model is achieved through the following technical solutions：
The wear-resisting cold-proof novel cable of outdoor, including conductor, be sequentially provided with outside conductor inner insulating layer, insulating layer, inner sheath,
Oversheath and external insulation layer, and packed layer is additionally provided between the inner sheath and oversheath, the packed layer is crosslinked using perforate
Polyethylene cotton.
The utility model has good lower thermal conductivity performance in itself using cross-linked polyethylene foam cotton, and in foamed open cell
Full of air, air thermal conductivity itself is told somebody what one's real intentions are, therefore is advantageous to ensure the shadow that cable internal layer is not changed by external high temperature or low temperature
Ring.It is mainly used in strengthening the anti-ultraviolet radiation performance of cable using inner insulating layer and external insulation layer, and uses inner sheath and outer shield
Set is mainly used in strengthening cable strength, resists mechanical external force damage, while is advantageous to play a supportive role to packed layer, prevents from filling
Layer is squeezed and influences its heat-insulating property.
Preferably, the thickness of the packed layer is 3mm, and the cross-linked polyethylene foam cotton coefficient of foaming is 20.
The cross-linked polyethylene foam cotton thickness or coefficient of foaming of packed layer are excessive, then influence that cable entirety can be substantially reduced
Shock resistance mechanical strength, if the cross-linked polyethylene foam cotton thickness or coefficient of foaming of packed layer are too small, it cannot be guaranteed that packed layer
Play good heat-insulating property.Therefore actual use situation is based on, the thickness for being preferably filled with layer is 3mm, the crosslinked polyethylene
Foam cotton coefficient of foaming is 20.
Preferably, the inner insulating layer is using the heat-protecting glass fibrous layer of coating fluorine dragon resin, the external insulation layer use
Black line style low density polyethylene layer.
The heat-protecting glass fibrous layer and black linear low density polyethylene (LLDPE) of coating fluorine dragon resin is respectively adopted in the utility model
Layer is used as external insulation layer, the main anti-ultraviolet radiation performance for strengthening cable.
Preferably, the insulating layer uses extruded polystyrene warming plate.
Extruded polystyrene warming plate thermal conductivity is low, and also with good resistance to compression and shock resistance, extruded polystyrene is protected in addition
Warm plate (XPS) has close hole-closing structure, and polystyrene molecular structure does not absorb water in itself, and the tow sides of sheet material do not have again
There is gap, there is moistureproof and air impermeability, and excellent anticorrosive property.
Preferably, the inner sheath enters uses PET steel band with oversheath.
By the way that interior oversheath to be ensured to the support of enhancing cable strength and packed layer, same phase using PET steel band
There is the thermal conductivity told somebody what one's real intentions are for ordinary steel belts.
The utility model compared with prior art, has the following advantages and advantages：
1st, the wear-resisting cold-proof novel cable of the utility model outdoor, the utility model use cross-linked polyethylene foam cotton in itself
With good lower thermal conductivity performance, and air is full of in foamed open cell, air thermal conductivity itself is told somebody what one's real intentions are, therefore is advantageous to ensure
Cable internal layer is not influenceed by external high temperature or low temperature change.It is mainly used in strengthening cable using inner insulating layer and external insulation layer
Anti-ultraviolet radiation performance, and use inner sheath and oversheath to be mainly used in strengthening cable strength, mechanical external force damage is resisted, simultaneously
Be advantageous to play a supportive role to packed layer, prevent packed layer to be squeezed and influence its heat-insulating property；
2nd, the wear-resisting cold-proof novel cable of the utility model outdoor, the cross-linked polyethylene foam cotton thickness of packed layer or foaming
Multiple is excessive, then influences that the overall shock resistance mechanical strength of cable can be substantially reduced, if the cross-linked polyethylene foam cotton of packed layer
Thickness or coefficient of foaming are too small, then it cannot be guaranteed that packed layer plays good heat-insulating property.Therefore actual use situation is based on, it is excellent
The thickness for selecting packed layer is 3mm, and the cross-linked polyethylene foam cotton coefficient of foaming is 20；
3rd, the wear-resisting cold-proof novel cable of the utility model outdoor,.
