In June 2019, Tellhow Technology Co., Ltd. won the bid for the procurement of low-voltage switch cabinets and power supporting equipment for the underground comprehensive pipe gallery (along the rail transit line 11) in the central urban area of Guangzhou. This is a leap of Tellhow Smart Power in ensuring the power distribution safety of integrated utility tunnels in central cities and serving the construction of smart cities.

        The underground comprehensive pipe gallery (along Metro Line 11) in the central urban area of Guangzhou is located in the central urban area of Guangzhou. It is the first pipe gallery project built in the central urban area in the country, with a total length of 48 kilometers and an investment of more than 6 billion yuan. After the project is completed, it will become the largest underground surrounding tunnel in Guangzhou. The pipe gallery is directly connected to the five districts of Tianhe, Baiyun, Liwan, Yuexiu and Haizhu, and has been built as a transportation "lifeline" integrating electricity, communication and water supply in the five districts of Guangzhou. The underground pipe gallery power cables will be connected in series with 11 existing substations and 3 planned substations in 5 districts of Guangzhou. The installed water supply pipes have a diameter of 1600mm, which can accommodate a large amount of water and form a high-speed channel for water supply. This project is a key demonstration project for promoting urban underground comprehensive pipe gallery nationwide.

        In August 2015, the General Office of the State Council issued the "Guiding Opinions on Promoting the Construction of Urban Underground Comprehensive Pipe Corridors" to comprehensively promote the construction of urban underground comprehensive pipe corridors, which means that the construction of underground comprehensive pipe corridors has officially risen from a local attempt to a national unity. pilot stage. In June 2016, the General Office of the Guangdong Provincial Government officially issued the "Implementation Plan for the Construction of Urban Underground Comprehensive Pipe Corridors in Guangdong Province", which clearly stated the goal for the next three years: by 2020, the province will build an urban underground complex of no less than 1,000 kilometers. Pipe gallery.

        As a high-quality enterprise specializing in providing "overall solutions for primary and secondary transmission and distribution systems", Tellhow Smart Power will leverage its basic industrial advantages in this project, benchmark against the highest international standards, deliver high-quality power equipment for the project, and join hands with the industry Elites, work together to build the city's underground "lifeline" to provide a strong power supply guarantee for the smart city.
