Transmission lines are the carriers and channels of power transmission, which are divided into overhead transmission lines and cable lines. The report according to the content is divided into line design, line construction, line operation and maintenance, new materials and new equipment four topics. (Source: China Electrical Engineering Society WeChat ID: csee-weixin) In the topic of circuit design, the author summarizes the recent achievements of China in UHV AC and DC transmission technology, large-span transmission line technology, multi-circuit transmission technology in the same tower, new wire technology, new tower structure, new tower foundation and flexible DC transmission technology , Power cable technology, the latest standards and engineering practice. In the topic of construction of the line, the latest standards and engineering practice of several new technologies in the group tower, the display technology of split wires, the construction technology of important cross-over construction, the technology of cableway transportation, and the technology of large- . In line with the topic of line operation and maintenance, the latest standards and engineering practice in China in terms of line inspection technology, galloping monitoring and control technology, anti-icing and deicing technology for transmission lines, and early warning and prevention technologies for geological disasters are summarized. In the topic of new materials and new equipment, the latest standards and engineering practices in recent years in our country are summarized in the aspects of new wire materials, new tower materials, large tonnage composite insulators and new line construction equipment. Through the above summary, it is pointed out that at present China has made positive progress in transmission line design, line construction, line operation and maintenance, and new material and new equipment. China has made major breakthroughs in the localization of its core technologies and key equipment and has implemented a number of technologies In the world's leading level. In the future, with the launch of the global energy Internet project, transmission line projects will face a variety of new extreme environmental challenges. At the same time, the requirements on the economy, leanness and environmental protection of transmission line projects will also continue to increase. Therefore, we must continue to vigorously promote the development and innovation of related technologies in transmission lines. Finally, some suggestions on the development of transmission line expertise are given: setting up a sense of innovation, keeping a close eye on key issues facing the actual project of the power grid, speeding up the training and stocking of qualified personnel, strengthening investment in scientific research funds and research hardware conditions, promoting interdisciplinary, Cross-disciplinary cooperation to comprehensively promote the relevant technical innovation of transmission line professional will lay a solid technical foundation for the protection of transmission line construction and safe operation. Polymer Concrete Cells For ER/EW Processing Of Nonferrous
Long-term impermeability, free of corrosion, 20+ years warranty
The structural core of electrolytic cells is bolstered with sturdy external seismic reinforcement blocks confining its floor supports, and includes a robust, internal bidirectional, pultruded FRP bar mesh reinforcement which positively maintains integrity should the cell fail due to catastrophic events. Electrolytic cell installation protocols call for lateral wall collaboration between cells,thus reducing stress levels of cell around 40% under normal operating conditions.

Electrolytic cells are designed, built and installed to satisfy the most stringent requirements requested by tankhouse operators worldwide. In most cases their main request is to guarantee full operating availability throughout the plant's lifespan, maximizing production of high-purity metal (copper, zinc, nickel, cobalt, lead or other nonferrous metals) with absolute safety for people and the environment. Additionally, cells must accommodate changes for continuous improvement of the electrolytic process, integrating efficiently with upgrades of complementary equipment such as anodes, cathodes, cap, boards, overhead crane electrolyte agitation systems, acid mist control devices, thermal insulation among many others.
The Internal layer is a monolithic tank made with multiple layers of fiber-reinforced vinyl ester resin (FRP) complying with chemical barrier international norms that assure long-term impermeability and corrosion resistance.
The Intermediate layer is the structural core made with polymer Concrete, with a patented formulation to achieve a low coefficient of thermal expansion, providing long-term structural integrity with low thermally-induced stresses
The External layer is a standard seal layer of FRP that further protects the structural core from electrolyte splashes and spills. Optionally,this external seal may be specified with multi-layered oriented fiber reinforcements to guarantee trouble-free operation in unusually extreme operating environments.
Benefits of electrolytic cells
Our monolithic internal tank manufactured with multiple layers of fiber-reinforced premium vinyl ester resin. It has continuous service without leakage, free of corrosion and structural flaws which operating under normal conditions as specified for each project.
Swift, accurate and less costly installation
Electrolytic cells include features that allow reduction of 25% or more in time needed for cell erection, alignment and leveling compared to time required with conventional polymer concrete cells. Dimension tolerances for electrolytic cells are consistently tight, simplifying installation in the most demanding applications,including plants with automated crane systems.
Minimum cleaning time and water consumption
The rounded internal shape,optional sloped cell floors,and smooth,flat finish of the internal tank,facilitate water sweeping and drainage of heavy sludge,with reduced water usage and accelerating return to service after each cleaning.
Minimum maintenance cost
The robust, virtually impervious internal tank that is chemically bound to the polymer concrete structural core during molding is tolerant to operating abuse its smooth,non-stick surfaces minimize adhesion of contaminants.
Maximum operational safety
