The State Intellectual Property Office has approved that the two products that have obtained invention patents are 750-1100kV ultra-high voltage cross-linked polyethylene insulated stainless steel sheathed photoelectric composite cable and 750-1100kV special High voltage cross-linked polyethylene insulated power cable.

750-1100kV UHV cross-linked polyethylene insulated stainless steel sheathed photoelectric composite cable products can meet the needs of UHV power transmission and transformation projects, smart grid online optical fiber measurement signals and data communications It is suitable for 750-1100KV ultra-high voltage power transmission and transformation systems. Its unique insulation layer made of cross-linked polyethylene material, copper wire shielding layer made of soft copper wire and stainless steel tube sheath make the cable have excellent Excellent mechanical properties and anti-corrosion properties, high short-circuit current capacity.

It is reported that 750-1100kV UHV cross-linked polyethylene insulated power cable products have good mechanical properties and anti-corrosion properties, are easy to install and maintain, and have good environmental performance. The metal shielding layer has sufficient transient short-circuit current capacity and is suitable for 750-1100kV ultra-high voltage and large-capacity AC transmission lines in large power stations.

Currently, there is no 750 in the world or in China that is suitable for ultra-high voltage and large-capacity AC power transmission and transformation, and can conduct online smart grid operation data collection and automatic control information transmission. -1100KV UHV cross-linked polyethylene insulated photoelectric composite power cable product. These two cable products have improved the existing cable structural performance, such as unstable performance, inconvenient installation and maintenance, and are not conducive to environmental protection. They are the first in the world.
