Abstract
The invention discloses an insulation material for an aerial cable. The insulation material consists of the following components in percentage by weight: 45 percent of polyvinyl chloride, 22 percent of plasticizer, 20 percent of filler, 11 percent of modifier, 0.4 percent of coloring agent, 0.1 percent of antioxidant, 0.05 percent of ultraviolet absorber, 1 percent of stabilizing agent and 0.45 percent of lubricating agent. The insulation material for the aerial cable has the high insulation performance of more than or equal to 1*10<11>omega.m, high low-temperature resistance, the low embrittlement temperature of less than or equal to -25 DEG C, ultraviolet resistance and the service life of more than 30 years, the current loss of the aerial cable is reduced by over 50 percent, and the requirement of the market on the high performance of the insulation material for the aerial cable is met.
Description
Technical field
The present invention relates to a kind of insulating material, particularly a kind of overhead line is used insulating material.
Background technology
Lower temperature resistance can be relatively poor when guaranteeing electrical property with insulating material for general overhead line.Overhead line uses insulating plastics all to be base mateiral with PVC RESINS, in PVC RESINS, adds auxiliary agents such as a certain proportion of softening agent, stablizer and mixes.In order to improve the electrical property of insulating plastics, take in original formulation, to add calcined kaolin, test-results is that when electrical performance indexes improved, resistance to low temperature descended to some extent.Through thinking, the selection of its auxiliary agent and the rational proportion between the auxiliary agent are the keys of index of enhancing product performance.Especially the cable user that has not only requires insulating plastics to have high electrical performance, and, also very high to the resistance to low temperature requirement of insulating plastics.So, how to guarantee that insulating plastics has under the prerequisite of high electrical performance, the resistance to low temperature that improves insulating plastics satisfies the demand in market, is the important topic that the scientific research personnel needs to be resolved hurrily.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome the deficiency of prior art, to provide a kind of good insulating, low temperature resistant overhead line to use insulating material.
For solving above technical problem, the technical scheme that the present invention adopts is:
A kind of overhead line is used insulating material, and its component is formed and the shared weight percent of each component is: SE 45%, softening agent 22%, weighting agent 20%, properties-correcting agent 11%, tinting material 0.4%, oxidation inhibitor 0.1%, UV light absorber 0.05%, stablizer 1%, lubricant 0.45%.
Further, described softening agent is selected dioctyl terephthalate for use.
Further, described stablizer is selected calcium-zinc composite stabilizing agent for use.
Further, described lubricant is selected Triple Pressed Stearic Acid and Chinese wax for use.
Overhead line of the present invention with the insulating material beneficial effect is: have excellent insulating property, insulating property>=1 * 10
11Ω .m, good low temperature cold tolerance, low temperature brittleness temperature≤-25 ℃, and can antiultraviolet can reach more than 30 years work-ing life, reduce the overhead line current loss more than 50%, satisfied market to overhead line with the high performance demand of insulating material.
Embodiment
Below in conjunction with embodiment the present invention is made further detailed description.
A kind of overhead line is used insulating material, and its component is formed and the shared weight percent of each component is: SE 45%, softening agent 22%, weighting agent 20%, properties-correcting agent 11%, tinting material 0.4%, oxidation inhibitor 0.1%, UV light absorber 0.05%, stablizer 1%, lubricant 0.45%.
Described softening agent is selected dioctyl terephthalate for use.
Described stablizer is selected calcium-zinc composite stabilizing agent for use.
Described lubricant is selected Triple Pressed Stearic Acid and Chinese wax for use.
Overhead line of the present invention has excellent insulating property, insulating property>=1 * 10 with insulating material
11Ω .m, good low temperature cold tolerance, low temperature brittleness temperature≤-25 ℃, and can antiultraviolet can reach more than 30 years work-ing life, reduce the overhead line current loss more than 50%, satisfied market to overhead line with the high performance demand of insulating material.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; And be not to be used as qualification of the present invention; As long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
