Description
Technical field:
The present invention relates to the anti-electric trace material of polyethylene kind, refer to a kind of Tracking Resistant Sheathing Compound for All Dielectric Self-Supporting Overhead Optic Cable especially.
Background technology:
The optical cable protective cover material that present domestic institute develops and produces is high density polyethylene protective cover material, medium density polyethylene protective cover material and low density polyethylene protective cover material.As the high density polyethylene protective cover material is to be base resin with the high density polyethylene, adds modified resin again and makes through the parallel dual-screw extruding pelletization with other adjuvant.The high density polyethylene protective cover material has good heat-resistant aging, environmental stress crack resistance, also has very high pulling strengrth, breaking elongation, is applicable to cable and cable cover(ing), and optical fiber is had enough protective effects.Machining process: all material is made through the parallel dual-screw extruding pelletization after the high-speed mixer high-speed mixing again.But on the optical cable in some particular surroundingss, it just can't reach the optical cable requirement as all dielectric self-supporting aerial optical cable.All dielectric self-supporting aerial optical cable (hereinafter to be referred as ADSS) is directly to lay on existing high-tension line, and circuit needn't have a power failure, and can lay the fiber number of big quantity simultaneously, and erected cost is cheap, but to optical cable, especially the electric erosion resistance of cable jacket has comparatively harsh requirement.The protecting sleeve of optical cable that domestic present institute develops and produces can't satisfy the requirement of its anti-electric trace.
Summary of the invention:
At the deficiencies in the prior art, technical matters to be solved by this invention has the following aspects:
1, the anti-electric trace sheath material of development solves (the galvanic corrosion phenomenon on induced voltage 12～20kV) optical cable surfaces in the highfield;
2, when solving anti-electric trace, give anti-environment, the against weather of the long-term outdoor use of the anti-electric trace sheath of aerial optical cable;
3, according to the characteristics of ADSS self-bearing type, this sheath system should possess high physical and mechanical properties.
Design of the present invention is that inorganic anti-electric trace agent is inserted in the polyvinyl resin of blending and modifying, makes the anti-electric trace sheath material of all dielectric self-supporting aerial optical cable.
Concrete technical solution of the present invention is as follows:
A kind of Tracking Resistant Sheathing Compound for All Dielectric Self-Supporting Overhead Optic Cable, be characterized in that it comprises base resin, anti-electric trace agent, antioxidant and lubricant, wherein base resin is the potpourri of high-density polyethylene resin and ldpe resin, and the percentage by weight of this protective cover material is as follows:

Anti-electric trace agent: 9.8%～25.0%;
Antioxidant: 0.8%～0.9%;
Lubricant: 1.1%～1.3%;
Above-mentioned high-density polyethylene resin density is 0.968g/cm
3, ldpe resin density is 0.922g/cm
3
Above-mentioned anti-electric trace agent is bismuth titanate or zirconia or zinc paste or alundum (Al or magnesium oxide or silicon powder or mica;
Above-mentioned preferable anti-electric trace agent is a zinc paste, and fineness is more than 300 orders, and addition is 13.0%～23.1% of this protective cover material total amount;
Above-mentioned antioxidant is antioxidant 1010, and lubricant is a Tissuemat E.
Technique effect of the present invention is:
1, all dielectric self-supporting aerial optical cable that adopts the present invention to make, by the international standard experiment, promptly anti-electric trace salt mist experiment IEEE, P1222 reach the requirement of anti-electric trace fully;
2, all dielectric self-supporting aerial optical cable that adopts the present invention to make, by resisting environmental stress and cracking test GB/T2951.8, by atmospheric exposure test GB12527, thereby guaranteed the environment resistant and weatherability of this optical cable, the medium-term and long-term operation of rugged surroundings that can be out of doors and not breaking down;
3, all dielectric self-supporting aerial optical cable that adopts the present invention to make has good intensity and length growth rate, can not rupture to guarantee that cable is in service after laying.
4, China introduces all dielectric self-supporting aerial optical cable the earliest, (being called for short the ADSS optical cable), it is nineteen ninety-five, development and application is rapid afterwards, about 4000～5000 kilometers of the ADSS optical cable of installing on the circuit at the beginning of 1999, the ADSS optical cable of installing to the end of the year 1999 has reached 10,000 kilometers, and this year, ADSS production at home will be above 10,000 kilometers.
At present the above power circuit of China 35kV surpasses 1,000,000 kilometers, and power communication with the optical cable development during swift and violent, if adopt the ADSS cable configuration, can save 8,000,000,000 yuan of the expenses of laying, economic benefit is very considerable.With 20 core ADSS optical cables is example, and market needs anti-electric track resistant jacket material 6～70,000 tons approximately, and industrialization prospect is considerable.
About 674.4 ten thousand yuan of profit.Utilize existing transmission line of electricity to set up ADSS, be China according to external technical experience, be fit to the scheme of economic and reliable of the actual national conditions of China, also be the needs that quicken communication of power system and automation development, so bigger social benefit is arranged.
During development was swift and violent, the anti-electric track resistant jacket material demand of ADSS in this year is estimated will be above 1000 tons with optical cable for power communication at present, and demand will double the coming years.
