Chinese utility taps G&W Electric to enhance grid reliability

Company’s global footprint continues to expand to meet demand for reliable power in APAC

Today, G&W Electric Co announced that it has completed the installation of two projects in China by replacing and upgrading equipment installed in Yiwu and Ningbo. The company said the new equipment will improve grid reliability as China utilities enter peak power demand during summer months. Both installations have been recently tested and are currently in operation.

In Yiwu, Zhejiang, a city of about 1.2 million, a total of 54 of G&W Electric’s 220kV Python Premolded Joints were installed in an underground cable line six miles long. The installation enables the power to be transmitted to an automated 220kV substation in city center of Yiwu.

About a two-hours’ drive northeast, in Ningbo, Zhejiang, the company’s PAT Style Slip-On terminations replaced defective equipment after the utility discovered an oil leakage throughout a competitor’s 110 kV cable terminals. G&W Electric replaced the defective 110kV units in the substation with Python terminations to ensure a healthier grid during peak summer months. 

Both projects were operated by Zhejiang Province of State Grid (SGCC), one of the largest utilities in China, responsible for power supply to 26 provinces across the country.

“G&W Electric is committed to working with utilities in China as it works to meet the growing demand for reliable and sustainable energy,” said John Mueller, Chairman and Owner of G&W Electric. “As China continues to recover from the pandemic, we were thrilled to be able to complete both projects as scheduled to prepare the grids for the peak power season.”
