CCTV News (Network Broadcast): On November 28, 2023, the main line of the Shenzhen-Zhongshan Link, a major transportation infrastructure project in the Guangdong-Hong Kong-Macao Greater Bay Area participated by Far East, was fully connected, marking a historic milestone. The 24-kilometer project connects Shenzhen, Zhongshan and Guangzhou, and is the most comprehensively difficult cross-sea cluster project ever built in the world.

Main Line of Shenzhen-Zhongshan Link Connected with Far East’s Participation    The Shenzhen-Zhongshan Link is a cross-sea passage connecting Shenzhen and Zhongshan, integrating bridges, islands, tunnels and underwater interchanges. Adopting an "eastern tunnel & western bridge" layout, the route starts at the Shenzhen Airport Interchange, connects to the second phase of the Guangzhou-Shenzhen Riverside Expressway, crosses the Pearl River Estuary westward, lands at Ma’an Island in Zhongshan, connects to the under-construction Zhongshan-Kaiping Expressway, and links Shenzhen, Zhongshan and Guangzhou via connecting roads. During construction, the project has set multiple world records, including the world’s first extra-long two-way eight-lane subsea immersed tube tunnel.

Far East provided high-quality, safe and reliable low-smoke zero-halogen, flame-retardant fire-resistant cables, aluminum alloy cables, and other low-voltage power and control cables for the project. These products are applied across the entire western bridge, middle island and eastern tunnel sections. Relying on strong R&D and technical capabilities, Far East adhered to the quality standard of "zero defects, zero complaints, zero reworks" to support the Shenzhen-Zhongshan Link.

A "Sky Bridge" Spanning the Bay – World’s Largest Span

With a span arrangement of 580m + 1666m + 580m, the Lingdingyang Bridge is a three-span fully floating suspension bridge, currently the world’s largest-span steel box girder suspension bridge over the sea.

A "Kunpeng" Rising at the Pearl River Estuary – World’s Largest Scale

The West Artificial Island of the Shenzhen-Zhongshan Link is 625 meters long, 456 meters at its widest point, and covers 137,000 square meters – equivalent to 19 standard international football fields. It is the world’s largest artificial island enclosed by steel cylindrical walls. Serving as a critical bridge-tunnel transition hub, it is a pioneering and pivotal project of the entire link, known as the "Kunpeng of the Sea" in the Greater Bay Area.

A "Hidden Dragon" Beneath the Lingding Sea – World’s Longest & Widest

The subsea immersed tube tunnel of the Shenzhen-Zhongshan Link is approximately 5,035 meters long, consisting of 32 immersed tube elements and one final joint. It is the world’s longest, widest and most comprehensively challenging steel-shell concrete subsea immersed tube tunnel.

As a major transportation artery linking city clusters on both sides of the Pearl River Estuary, the Shenzhen-Zhongshan Link will form a cluster of cross-sea and cross-river passages in the Greater Bay Area together with the completed Hong Kong-Zhuhai-Macao Bridge, Nansha Bridge and Humen Bridge. It is scheduled to open to traffic in June 2024, cutting travel time from Zhongshan to Shenzhen from about two hours to under 30 minutes.

Far East Cables Safeguard the "Central Nerve" of the Shenzhen-Zhongshan Link

To ensure safe tunnel traffic, an intelligent traffic management and control system has been developed for the Shenzhen-Zhongshan Link. Various sensors installed in the tunnel enable active and rapid accident detection. In case of fire, high-pressure water mist and foam fire suppression systems on the tunnel ceiling can be activated remotely with one click from the control room, buying valuable time for evacuation.

The "neural network" transmitting these signals is housed in the tunnel’s middle pipe gallery, which has three layers. The lowest layer accommodates power and optical cables, water supply, drainage and fire pipelines – the central nerve for safe operation. The middle layer serves as transverse escape passages, and the top layer is a smoke exhaust channel, allowing evacuation to opposite lanes during accidents or fires. Cables supplied by Far East feature zero halogen, low smoke, flame retardancy and long service life, with additional advantages:

For conductors, high-quality oxygen-free copper with a copper content of 99.95% or above is used for excellent conductivity. Fire-resistant cables are equipped with mica tape layers, fully complying with the latest national standard GB/T 19666-2019, ensuring continued power supply for a period during fires to support alarms and rescue operations.

For insulation, silane cross-linked polyethylene (XLPE) with superior insulation and heat resistance is adopted for excellent electrical safety. The outer sheath uses high-performance low-smoke zero-halogen polyolefin compound. Gas emissions during combustion meet GB/T 17650.2 (pH ≥ 4.3, conductivity ≤ 10 μs/mm), and light transmittance meets smoke density requirements in GB/T 17651.

Flame retardancy meets IEC standards, effectively preventing flame spread along cables. B1-class cables comply with combustion performance requirements in GB 31247-2014 "Classification of Burning Performance of Cables and Optical Cables".

Far East’s Premium Services Support National Major Projects – Service, Quality & Reputation

"Winning the market with superior products and services and earning lasting user trust is responsibility and respect to customers, and a key foundation for high-quality corporate development," said Jiang Xipei, Founder, Chairman of the Board and Secretary of the Party Committee of Far East Holding Group. Jiang Jun, project director, stated: "Though the road is long, the journey will surely end; though the task is hard, the work will surely succeed. We take great pride in participating in this world-class project." Li Lin, Supervisor of the Cable Industry, Chief Customer Officer, Far East National Master and Engineer, and Xiao Zheng, Senior Partner and Customer Officer of Far East Energy, led six trips to Guangdong to support project completion, providing premium full-cycle services from bidding to delivery. Far East delivered with excellence.

Far East Cable has been widely used in major international events and national key projects including China Zun, Beijing 2022 Winter Olympics, Hong Kong-Zhuhai-Macao Bridge, Shanghai World Financial Center and Shenzhen-Zhongshan Link. The company is steadily advancing toward its goal of "becoming a global leader in the cable manufacturing industry".
