gui chao cable news: the development trend of china's electric power special optical cable standardization-非凡电子娱乐

the development of special optical cable in power system is rapid, and there are more than 10 kilometers of special fiber optic cable line.

uhv ac and dc demonstration projects, the use of optical fiber composite overhead ground wire.

the performance and quality of special optical cable is directly related to the safe and stable operation of power grid.

however, due to the relatively short time in the application of special optical cable products in china,

the standard quantity and type can not meet the needs of production and operation,

there are still some deficiencies in the standardization of the special optical cable in china.

special fiber optic cable and its installation accessories (hardware, joint boxes, etc.) has not formed from the design,

the complete standardization system for production, testing and testing to engineering bidding, construction and acceptance.

domestic special fiber optic cable model complex, the same voltage level of each line,

even the lines of different types of special fiber optic cable, there is no relatively uniform type.

this is not conducive to engineering design, production, maintenance, deployment, resulting in the design, production,

project cost is high, but also caused the inconvenience and waste of construction.

in recent years, the application of optical fiber composite phase lines in china,

domestic manufacturers have also developed a number of optical fiber composite phase line products,

and a small amount of operation at 10 thousand v and 35 thousand v lines,

at the same time began to apply on the 110 thousand volt line.

but at home and abroad, the optical fiber composite phase line is generally refer to the wire and optical fiber composite overhead ground wire (opgw) standard for structural design and testing,

there is no authoritative recognized national or industry standards, design, construction, quality testing, inspection and other aspects of the factory has not been uniform.

with the development of society, the power grid construction will develop to the high voltage and large capacity in the future,

special optical cable structure must meet the requirements of the advanced, applicable and reliable requirements of different voltage levels.

the revision of the standard should take into account the opinions of the departments of operation, research, design and manufacture,

taking into account the needs of design, construction, maintenance and manufacturing, fully embodies the scientific and rational.

the system should not only take into account the safety and reliability of the system, but also consider saving resources and environment,

the formation of a practical, scientific and rigorous, complete and comprehensive standardization system.

standardization work should also adapt to the development of special optical cable, establish and improve the standardization system.

in particular, the uhv line has a large capacity, a long distance and a more complex environment,

this requires the standard to adapt to the requirements of uhv environment.

uhv ac, dc demonstration line and has been put into operation,

on the basis of the actual operation, the corresponding design, production and operation standards should be formulated for the future.

we should increase the investment in the basic research field of special optical cable in order to adapt to the new technology and new varieties of special optical cable,

new products and the need to solve new problems, to meet the needs of the rapid development of special optical cable,

taking the uhv ac and dc research as an opportunity, this paper makes an in-depth study on the performance and application of special optical cable,

the new research results in the field of special optical cable as soon as possible to form a corresponding standard,

gradually improve the international influence of china in the field of special optical cable standardization,

to make china's standardization system among the world's advanced ranks.
