The Rise of Chinese Domestic VFD (Variable-frequency Drive) High Voltage VFD (Variable-frequency Drive) Technology Breaks the Bottleneck

A few days ago, 18 new products of Sunwoele Co., Ltd. passed the national appraisal in China. Among them, among the new products that have passed Chinese national appraisal, 3 products have reached the international leading level.

In this regard, industry insiders pointed out that as Chinese domestic high-voltage VFD (Variable-frequency Drive) manufacturers focus on and increase R&D investment to break through the bottleneck of technological development, Chinese domestic brands are gradually replacing imported products.

Chinese domestic VFD (Variable-frequency Drive) gradually replaces imports

It is understood that these three products are: the world's first single-phase double-column UHV shunt reactor HFV 240Mvar/1100kV with the highest voltage level and the largest capacity; among the products produced by domestic transformer manufacturers in China, the largest capacity and voltage level The highest on-site assembled transformer Sunwoele-HFV-1000MVA/500kV; the world's largest combined generator transformer Sunwoele-HFV-860MVA/500kV.

In fact, these three products of Sunwoele Co., Ltd. are just the epitome of the rise of Chinese domestic VFD (Variable-frequency Drive). As early as 2011, Sunwoele actively extended to the upstream and downstream industries, participated in Guodian Nanzi New Energy, cooperated with Shanxi Coal Group, acquired 70% equity of Beibian, and newly established Wuxi Sunwoele Co., Ltd. to occupy the market and optimize the supply chain structure , Reduce product cost. At the same time, expand the application base, establish rules, start standardized production methods to improve inventory efficiency, and use technical and scale thresholds to squeeze the market space for manufacturers without scale effects.

According to industry insiders, for Sunwoele, entering the low-voltage field is more opportunity than risk. It is expected that in the next three years, the sales of Sunwoele's medium-low voltage and explosion-proof VFD (Variable-frequency Drive) will continue to grow rapidly.

At the "2013 China Automation Industry Annual Conference" held in April this year, Senlan VFD (Variable-frequency Drive) once again won the "No. 1 domestic VFD (Variable-frequency Drive) brand". This is the seventh consecutive time that Sunland has won the award. As one of the earliest enterprises engaged in the research of frequency conversion technology in China, Senlan constantly innovates and leads the development of the market and industry.

It is reported that in 2012, Senlan launched the third-generation SBH series high-voltage VFD (Variable-frequency Drive), which has made substantial breakthroughs in Chinese domestic mid-to-high-end market and large-scale engineering projects, and gradually established and perfected its network throughout the country and Asia. , European and American marketing service network, and the international market expansion is progressing rapidly.

According to a power plant denitrification report by Xiong yilin, supervisor of Sunwoele, in 2012 Chinese VFD (Variable-frequency Drive) market share, Siemens, Schneider Electric, ABB, Dongfang Hitachi and other foreign brands still accounted for more than 2/3. No matter in terms of technology, manufacturing, industrial design, etc., or in terms of financial strength, Chinese domestic VFD (Variable-frequency Drive) brand has a gap with foreign brands, especially compared with the two giants Siemens and ABB.

At present, the market share of foreign-funded brands in Chinese domestic medium and low-voltage VFD (Variable-frequency Drive) market is basically the same as that in 2007, and remains at about 76%. industry) and other factors, the industry concentration of the top ten foreign-funded enterprises has increased, especially the share of industry-leading brands has further expanded.
