HENGTONG Group is the initiator of smart grid industry alliance nationwide. It develops cable solutions adaptive to power transmission over the smart grid, including high-capacity high-voltage and extra-high-voltage electrical cables and optical cables. Its products cover cables for urban and rural grids, as well as overhead lines and underground cables including overhead conductors and OPGW, OPPC, ADSS, OPLC, low-voltage buried cables, medium-voltage cables and XLPE cables of 500KV or below that are applicable to long spans. They have been widely applied in numerous projects around the world and survived stringent tests. Among them, OPPC of HENGTONG creates a world record with the highest voltage class in China, and OPGW of HENGTONG creates multiple world’s firsts such as the largest cross section, the highest capacity, the longest span, the best thunder-proof performance and the biggest icing load.

HENGTONG has invested and established world-class production bases for extra-high-voltage electrical cables and undersea cables, and introduced a full set of world’s top equipment for extra-high-voltage cables and submarine cables. It owns a 180-meter-high VCV tower, the highest in Asia, and a submarine cable terminal that can accommodate two 10,000-DWT ships.  HENGTONG has also independently developed the high-voltage (500 kV), large-cross-section (2,500 mm2), and long-spanning (over 50 km) XLPE optical fiber composite submarine wires, flexible and long high-voltage DC submarine composite wires (±320kV) and flexible joints of submarine cables, all of which have reached the top level in the world. The “ultra-length feeding repeaterless submarine optical cable” of HENGTONG breaks the bottleneck in the domestic market and becomes an alternative of imported products.

HENGTONG has launched smart building system solutions with comprehensive management of the energy efficiency as the core. All the information is integrated through establishment of communication networks, energy consumption data collection and management, power distribution monitoring, smart office and self-management of buildings, so that the solutions can be interconnected with the building construction equipment management and public security management systems. In this way, a safe, reliable, comfortable and convenient modern smart building featuring energy-conservation, environmental friendliness and economical efficiency can be created.
