The researchers who formulated this technical specification conducted on-site investigation and Analysis on the operation failure of OPGW downlead in this case. After investigation and analysis of actual cases and simulation
With the continuous development of wind power construction in China, a series of megawatt wind power bases have been built in North China. The construction of megawatt super large wind power bases in Hexi Corridor puts forward higher requirements for the
OPGW cable is widely used in power system. OPGW cable is a lot of new lines. At the same time, the installation of OPGW cable fittings is particularly important. How to standardize the installation of OPGW cable accessories? Today, I would like to give yo
OPGW optical cable is a kind of special optical cable commonly used in power system. It has high mechanical strength and reliability, but it is expensive. It is only suitable for new or planned transformation lines, and its application is limited.
Feature 1: high strength. Due to the large contact area between the suspension clamp and the conductor in the pre twisted power fittings, the stress distribution of the conductor is more uniform during clamping, which greatly reduces the stress of the
The structure of OPGW cable the application structure of OPGW cable has experienced the development process from the end of 1970s to 2000. Dozens of OPGW cable structures have been developed and produced in the world. The cable core structure is as follow
With the extensive use of optical cable, the main factors of dry band arc corrosion of ADSS optical cable gradually exposed its own defects, which restricted its further development. The most prominent is the phenomenon of electric corrosion, mainly inclu
