Resolving the issue of becoming overly large
Based on the 2026 Top Runner Standards (Third Judgment Criteria), designing and manufacturing molded transformers tends to result in larger units compared to those made under the old standards. Therefore, when replacing transformers made under the previous standards with those meeting the 2026 criteria, it is anticipated that they may not fit into the original space. In such cases, Rishou Industry can respond with a "Retrofit Exchange" of top runner molded transformers. Retrofit exchange refers to the process of perfectly fitting a replacement product into the space where the original item was located, similar to replacing old wooden window frames with aluminum sashes. According to materials from the Japan Electrical Manufacturers' Association (JEMA), as of 2021, there were 190,000 molded transformers operating in Japan that do not even meet the first judgment criteria established in 2007, accounting for nearly 60% of the total. These units may have already significantly exceeded their recommended replacement period and could be entering the "wear and failure phase," so we recommend planned replacements. If you encounter the "tendency to become larger" issue, we welcome you to consult with us about the "Retrofit Exchange."

basic information
The retrofit design of the riser cast transformer first designs the width of the 2026 Top Runner standard compliant product, which tends to be larger than the old standard products, to be the same as that of the old standard products. Next, by increasing the height and depth, we achieve equivalent capacity. Since each situation is expected to be different, we can also accommodate requests to widen the width and reduce the height. Additionally, we offer detailed retrofit designs tailored to the specific circumstances of each customer, such as aligning the pitch of the wheels and the position of the installation bolts, as well as considering cable routing.
