G&W Electric 220kV Cable Joints Installed To SGCC For 2016 G20 Summit
Published 18 May 2021
Geoffrey Cao (VP Global Operations – Energy Business) has kindly contributed the following Guest Blog emphasising the requirement for reliable high voltage electricity distribution and supporting cable accessories.
The Article explains the successful installation of G&W Electric cable joints and terminations to the State Grid Corporation of China, the largest electric utility company in the world and a state-owned transmission and distribution company.
In November 2015, G&W Shanghai received the mega 220kV cable joint order from the State Grid (SGCC) local company of Hangzhou City – the order comprised 88 units of cable joints and 6 units outdoor cable terminations for the 220kV extra high voltage network.
The project is to bury 2 circuits of 220kV overhead line to underground, as part of the infrastructure budget to renovate Hangzhou City to prepare for the G20 Summit that is scheduled in September 2016.
The G&W Electric products supplied are oil insulated outdoor terminations with composite insulator and pre-expanded cold shrink one-piece insulated cable joint.

After some international events like the 2008 Olympic Games, it is well known to the world, how structured the Chinese government arranges such events, thus the significance of this project is not only customer’s acknowledgement of the high quality and reliability of product being supplied, but also the ability of on time completion of project thus subsequent construction will immediately follow the cable project completion.
The delivery of such a large volume of cable joints for 2500sqmm cable, the largest 220kV cable size, were done within 1.5 months, thanks to G&W advanced moulding technology with such a high output, efficiency and yield rate.
As standalone EHV accessory company, G&W earned high reputation to work with many cable companies for the EHV cable system in past, and this time, the accessories will be coupled with several different Chinese local cable companies.
G&W is also providing the on-site installation of all accessories supplied, which is also featured with tight time schedule due to the forthcoming Chinese new year, thus constructors will have a long holiday.
“This mega project is another good example for G&W to demonstrate ability to supply bulk quantity of extra high voltage product and our versatility to work with different cable companies for important cable system work” commented by Mr. Jim Solari – G&W Electric.
