Abstract
The present invention relates to a kind of anti-ultraviolet cable and/or cable line of at least one hyaline layer including the coloured sheath of at least one electric insulation and around the electric insulation sheath.
Description
Technical field
The present invention relates to a kind of anti-ultraviolet cable and/or cable line, it includes at least one coloured electric insulation shield
Set and at least one hyaline layer around the electric insulation sheath.
Background technology
The present invention generally but not exclusively be applied to for transmit electric power and/or for transmit data cable and/or
Cable line, be particularly suitable for for example ultraviolet (UV) radiation level place higher (for example, coastal area, desert, ocean,
High mountain, by equatorial area) the open air cable and/or cable line that are used.Cable and/or cable line are generally included
One or more electrically and/or optically the elongated conductive member of type and around it is one or more of electrically and/or optically
The external electrical insulation sheath of the elongated conductive member of type.External electrical insulation sheath can be coloured, with to user and/or dimension
It is what kind of cable that the personnel of repairing indicate it.When these cables are located at it is outdoor when, they undergo high-caliber UV radiation and
Oxygen and other stress (for example, water, high temperature, ozone etc.) in air, cause external electrical insulation sheath premature aging.This be because
For the polymeric material (for example, polyolefin, polyvinyl chloride) for being generally used for external electrical insulation sheath is radiosensitive to oxidation and UV.
Additionally, UV radiation be typically used for colouring the external electrical insulation sheath of cable have colour additive (for example, there is engine dyeing
Material) photodegradative reason.Especially, colored materials can absorb UV lines, cause specific photochemical reaction, such as：Chain splits
Solution；Form double or triple bonds, ion, ejected electrons or most common free radical；Eliminate small molecule；Or crosslinking.These reactions exist
Cause bad and irreversible change in performance, such as：Fading, (that is, the priming color outward appearance of external electrical insulation sheath does not have
It is lasting to exist), the change of face crack and deformation, tensile strength and enhanced stretch resistance etc., ultimately result in external electrical insulation sheath
The deterioration of functional performance (physics, machinery, aesthetics etc.) and its lost of life.
There are several solutions to can be used to protect the coloured external electrical insulation sheath of cable not damaged by UV lines at present.
The first solution is to mix one or more stabilization in constituent to the external electrical insulation sheath of cable
Rather than polymeric material and/or colored materials, the effect of the stabilizer is capture UV radiation for agent (for example, UV absorbents), and
Heat is converted radiation into, heat is then distributed on the surface of electric insulation sheath.At present, most widely used UV absorbents are
Carbon black.Thus obtained external electrical insulation sheath is that the carbon particle in black, and the sheath fully absorbs UV lines and incites somebody to action
It is converted into heat energy.Sometimes, coloured positioning strip is added to black external electrical insulation sheath.
However, the solution can not manufacture the external electrical insulation sheath with the color in addition to black, or can not
Coloured positioning strip is shown in the color in addition to black.
US 5 355 427 is provided and is used the external electrical insulation sheath in orange polyvinyl of anti-UV lines.However,
The constituent of the sheath is not described.
Light stabilizer (that is, UV stabilizer) can also be used in the external electrical insulation sheath of cable.They absorb unlike UV
Agent equally absorbs UV lines；On the other hand, they make to be deposited in electric insulation sheath by neutralizing the free radical of photochemical reaction generation
Material from the free radical adverse effect, so as to slow down any chemical degradation.
However, generally can not prevent described using stabilizer (UV absorbents, UV stabilizer) in colored electrodeposition insulating sheath
Priming color at jacket surface fade away or color change, particularly ought these stabilizer relative nullities wherein
When generating free radical at the surface of sheath.
Another solution is that version is polymerization including makrolon, acrylonitrile-butadiene-styrene (ABS) etc.
Thing material and around at least a portion cable for being easily exposed to UV lines groove or pipeline (for example, for installing leading for cable
Pipe) type rigid protective system.These protection systems are not the parts of cable.Additionally, because such protection
System must be set up around cable, so indicating extra manufacture and installation cost using the protection system.Further it is necessary to
Removing protection system could observe the color of cable.
It is therefore an object of the present invention to pass through offer can be used (particularly in the place that UV radiation levels are high) out of doors
Coloured cable and/or cable line for transmitting electric power and/or transmitting data, ensureing cable and/or cable line
The technical disadvantages of prior art are overcome while good color retention and good electromechanical properties.
