With the rapid development of the national economy and power industry, the domestic 750-1100kV UHV, large-capacity, long-distance AC transmission and transformation project has been launched on a large scale, the construction of smart grid is in full swing, and the cable industry has recently added two related invention patents
.
The State Intellectual Property Office approved that the two products that obtained invention patents are 750-1100kV UHV XLPE insulated stainless steel set photoelectric composite cable and 750-1100kV UHV XLPE insulated power cable
.
750-1100kV UHV XLPE insulated stainless steel set photoelectric composite cable products can meet the needs of UHV transmission and transformation engineering smart grid online optical fiber measurement signal and data communication, suitable for 750-1100KV UHV power transmission and transformation system, its unique cross-linked polyethylene material made of insulation layer, soft copper wire made of copper wire shielding layer and stainless steel pipe sheath and other design, so that the cable has excellent mechanical properties and anti-corrosion performance, high short-circuit current capacity
.
It is reported that 750-1100kV UHV XLPE insulated power cable products have good mechanical properties and anti-corrosion performance, easy installation and maintenance, good environmental performance, metal shielding layer has sufficient transient short-circuit current capacity, suitable for large power station 750-1100kV UHV, large-capacity AC transmission lines
.
At present, there is no 750-1100KV UHV XLPE insulated photoelectric composite power cable products suitable for UHV large-capacity AC transmission and transformation, and can carry out smart grid operation data collection and automatic control information transmission online
.
These two cable products have improved the existing cable structure performance is not stable enough, inconvenient installation and maintenance, not conducive to environmental protection and other problems, is the first in the world
