Ningbo Tonyhoo Electrical Technology Co., Ltd., formerly known as Ningbo Jobhost Cable Accessories Co., Ltd., is the first enterprise in China to domestically produce copper shells for high-voltage intermediate joints. In 1997, the product was launched on the market and obtained certification from domestic authoritative institutions to achieve mass production. At the same time, it was also recognized by foreign enterprises such as Japan and the United States, and cooperation was reached. The enterprise has been focusing on the improvement and research and development of the copper casing for high-voltage intermediate joints for 25 years. It has continuously improved the process and upgraded its products, achieving a leading position in the segmented market and occupying a large market share. The product involves voltage levels such as 35kV, 110kV, 220kV, and 550kV, among which 550kV is currently the only enterprise in China that has been certified by an authoritative organization.

The main product of the enterprise is the copper shell of the high-voltage intermediate joint, which is an essential supporting product in the field of high-voltage cable transmission and distribution engineering. It plays an important protective function of insulation and waterproofing to ensure the safe and smooth operation of the cable line. Among them, the "flame-retardant cable insulation protection shell" compensates for the industry's shortcomings, and the product is used in high-voltage transmission and distribution projects such as the State Grid and Southern Power Grid. It is mainly matched with leading enterprises in the industry such as Changlan Electric Technology Co.,Ltd,、CYG Electric Co., Ltd.and 3M. Our products account for over 60% of the domestic market, with customers in the cable and power industry across the country. We are a domestic production enterprise specializing in insulation intermediate joint copper shells, and our competitors have a small portion of our own supporting equipment. In addition, there is a certain gap between our company in terms of enterprise qualifications, product structure, production process, core technology, and other aspects in the market. Due to research and development investment, management costs, and other reasons, we only have a certain advantage in sales prices. The insulation, impact, withstand voltage and other technical indicators of the product have been tested by Wuhan High Voltage Research Institute and qualified reports have been obtained. The product has more than 30 patents and has been legally protected for intellectual property rights through legal means, and has received victories and support.

The enterprise introduced new material projects in 2020, invested in the establishment of a new material laboratory and professional talents, and applied for the municipal engineering center. We fully rely on customer needs and combine market feedback to ensure the industry application of research and development results and convert them into economic value. Every year, enterprises will allocate about 6% of their research and development funds for research and improvement.

The company has been rated as a national high-tech enterprise for 15 years, an AA level contract abiding and trustworthy unit for 19 years, an excellent supplier quality award for 19 years in 2020, a technical cooperation unit in 2020, a council member of Ningbo Electric Power Industry Association in 2020, and an excellent supplier for 2019 to 2020 in 2021.

On the basis of the original New Third Board, the enterprise established Ningbo Tonylum New Material Technology Co., Ltd. and Ningbo Crelence Electric Technology Co,Ltd., by the end of 2020, radiating from the existing high-voltage cable accessories field to the medium and low voltage and new material fields, expanding the previously monopolized niche market again. The two enterprises gradually completed various qualifications and certifications starting from 2021, achieving further development. Relying on the industry's 25 year market foundation and high-quality reputation, combined with the advantage of highly overlapping customer groups, the company will achieve growth in output value. And increase investment in innovation, complete the transformation of the automation workshop, and gradually achieve digitization. Therefore, it is planned to carry out a second share reform in the next two years and advance towards IPO.
