Empowering the Arteries of the Greater Bay Area! Guanggao Electric infuses enduring power into Haizhu Bay Tunnel.

Empowering the Arteries of the Greater Bay Area! Guanggao Electric infuses enduring power into Haizhu Bay Tunnel.

2026-02-06

Recently, the Guangnan Expressway (including the tolled Haizhu Bay Tunnel and the southern section of the free connecting line) has opened to trial operation. As the "No.1 Shield Tunnel of Guangzhou" – Haizhu Bay Tunnel – runs through the Pearl River South Waterway, this 4.36-kilometer transportation artery linking Haizhu and Panyu is ready to set sail.

As the core power guarantee for this super project with a total investment of over 10 billion yuan, the high-efficiency and energy-saving dry-type transformers tailor-made by Guangzhou Guanggao High-Voltage Electric Co., Ltd. (hereinafter referred to as "Guanggao Electric") have built an indestructible energy foundation for the tunnel’s permanent power supply system, keeping the pulse of urban transportation beating strongly and continuously.

Having been deeply rooted in the power equipment sector for more than six decades, Guanggao Electric has evolved from a former national second-class enterprise into a national-level specialized, sophisticated and innovative "Little Giant" enterprise. The track record of over ten thousand transformers operating safely across the country stands as the best testament to its core competitive strength.

For the special humid and dusty environment of the tunnel, Guanggao Electric has adopted its proprietary patented technologies to provide dry-type transformers featuring moisture and dust resistance, high efficiency and energy saving, low noise and low partial discharge, as well as strong resistance to sudden short circuits. It has built a solid safety defense line with solid insulation technology, perfectly meeting the power demand of all scenarios such as tunnel lighting, ventilation and monitoring.

Its integrated energy-saving core technologies not only ensure the stability of power supply but also practice the concept of green and low carbon, resonating in step with the project’s strategic positioning of advancing the integration of the Guangdong-Hong Kong-Macao Greater Bay Area.latest company news about Empowering the Arteries of the Greater Bay Area!

From precise voltage conversion and low-loss long-distance transmission to all-weather stable operation and adaptation to harsh environments, Guanggao Electric integrates its six decades of technological accumulation into every piece of equipment through a digital intelligent design and an integrated quality control system. As the Haizhu Bay Tunnel will drastically shorten the commute between the central urban area and Guangzhou South Railway Station and ease regional traffic pressure in the future, behind this remarkable project lies not only the exquisite craftsmanship of tunnel engineering, but also Guanggao Electric’s steadfast commitment to empowering urban development with power technology.
