Recently, State Grid Corporation and its various local companies, in accordance with the relevant provisions of the "State Grid Corporation Supplier Misconduct Handling Management Rules", successively notified and dealt with 81 non-compliant suppliers in mid-September. In the notification from State Grid Chongqing Electric Power Company, TBEA Shenyang Transformer Group Co., Ltd. was found to have "two batches of oil-immersed transformers failing the temperature rise test", resulting in the suspension of its bidding qualification for related 10kV oil-immersed transformer product packages for 4 months. This is not the first time a TBEA subsidiary has been "listed". In early September, State Grid Jibei Electric Power Company reported that TBEA Shandong Luneng Taishan Cable Co., Ltd. supplied 10kV power cables with quality issues, and the related products were suspended from bidding for 2 months. Last year, the company also faced strict punishment from State Grid, which stated that its "attitude towards rectification was extremely poor", and reduced its total bidding volume by 40%. In the notification from Gansu Electric Power Company, Huayi Electric's "sampled disconnectors failed the short-time withstand current test", and related products were suspended from bidding for 2 months. In the notifications from Gansu and Mengdong Electric Power Companies, subsidiaries of XJ Electric and NARI Technology were also listed, and this is far from their first punishment. Several NEEQ-listed companies, such as Jiangsu Zhongling High-Tech, were also punished for product quality issues. What impact will the suspension of bidding for several months have on the companies? A relevant person from TBEA Shenyang Branch stated that company leaders are currently on business trips and cannot answer reporters' questions. Meanwhile, a staff member from Huayi Electric's Securities Department told reporters that perhaps due to the relatively small contract, they were not aware of the punishment. Generally, only electrical equipment contracts worth over 100 million yuan are reported to the Securities Department and meet the information disclosure standards, so they are not clear about the matter. A staff member from Jiangsu Zhongling High-Tech admitted to reporters that they are not yet aware of the situation and will verify it immediately. If the bidding suspension lasts for 2 months, it will not have a significant impact on the company's operations, but the company's credibility and reputation will certainly be affected to some extent.
