New production facility for power capacitors

31 March 2015

TDK has opened a new production facility for EPCOS power capacitors at its Zhuhai FTZ plant in China.

In doing so, TDK is expanding and consolidating its power capacitor production based in China. Besides capacitors, TDK manufactures a wide range of EPCOS protection devices and temperature sensors at the plant – not just for the rapidly growing Chinese market, but also for global sales. The plant is located in the Free Trade Zone (FTZ) of this coastal city, which is very close to Hong Kong.

Focus on the Chinese market for power electronics

The new production building with its floor space of 8000 square meters houses the production for three product groups: PEC, PFC and MKP capacitors. These components are used in industrial electronics applications, such as electric rail systems, high-voltage DC (HVDC) transmission systems, power factor correction (PFC) systems, and in industrial drives.

About 70 per cent of the power capacitors produced in Zhuhai are destined for the Chinese market. Dr. Werner Lohwasser, General Manager of TDK's Aluminum and Film Capacitors Business Group notes, driven by extensive state investment in the infrastructure of the country, China is well on the way to becoming the world's largest market for power electronics. With the help of competent local workforce, they will be able to serve the large demand for power capacitors in China with products made in China. This investment is moving TDK even closer to its customers in China, where it can provide technical support in their own language and considerably shorten delivery times of its products. 

15 years of growth

The production of ceramic elements for varistors started at the Zhuhai FTZ facility in the year 2000. At that time, the plant covered 7000 square meters and employed about 240 people. Since then, the production area and the capacities have grown continuously: Today, Zhuhai FTZ has a production area of nearly 50,000 square meters and a workforce of about 3000. Two hundred more jobs are to be created by the new capacitor production.

Dr. Herbert Poelzl, who has managed the plant for four years said that the last 15 years have been marked by very fast growth. In addition to the frequent construction of additional production lines, they are also increasing the research and development based here. At present, they have almost 130 engineers. 
Wide range of products for numerous applications

Today, the plant manufactures a wide range of different product technologies. In addition to varistors, the range includes inrush current limiters and PTC thermistors for applications not only in industrial electronics and power engineering, but also in automotive and consumer electronics. In addition to the power capacitors, the Zhuhai factory also manufactures DC capacitors, which are predominantly used for the suppression of electromagnetic interference in electrical systems and devices. Also the temperature sensors produced here are used mainly in automotive and consumer electronics sectors.
