Xi’an XD High Voltage Apparatus Co. Ltd., based in the northwest of China, is a leading manufacturer of innovative high-voltage equipment. The increasing demand for high-power systems that are small in footprint challenges the PTD manufacturing industry. By relying on Stäubli’s latest MULTILAM innovation ML-CUX, Xi’an XD High Voltage Apparatus benefits from a high performance contact element with flexible design and excellent short circuit carrying-capacity to provide its customers a very efficient solution.
In the northwest of China, the city of Xi'an was the capital of the Qin Dynasty, the first Chinese unified empire. From here you can discover traditional Chinese landmarks such as the terracotta army or the starting point of the Silk Road. Today, with over 7 million inhabitants, the city is also the research, development, production and sales location for one of China's largest switchgear manufacturers. Xi’an XD High Voltage Apparatus Co. Ltd. has more than 50 years of experience in designing high-voltage equipment. Based on advanced technologies, their products are known for their reliability and used worldwide.
Gas Insulated Switchgears (GIS) are more reliable in harsh environment, clearly require less space with a footprint as much as 70% smaller and are cost effective in operation due to less maintenance. Pluggable connections allow for thermal expansion in response to temperature fluctuation and facilitate the design of smooth and rounded shapes to minimize the electrical field strength. This results in higher withstand voltage and also makes for shorter insulation distances or smaller switchgear sizes. Above all, pluggable connection solutions reduce assembly and maintenance costs.
The increasing demand for energy and the associated expansion of existing power grids call for powerful and highly dependable equipment. The miniaturization of installations and systems requires a reduction in size of all machinery and components without compromise in performance. At the same time, energy suppliers and power stations pay very close attention to their operating and maintenance costs.
The challenge for Xi’an XD High Voltage Apparatus is to provide very reliable, high-power but still economical equipment. Always in search of ways to improve their design concepts, Xi’an XD High Voltage Apparatus was looking for a space-saving, extremely solid contact element with high performance characteristics.
The latest Stäubli innovation in its electrical connectors’ portfolio piqued the engineers’ interest at Xi’an XD High Voltage Apparatus. The MULTILAM ML-CUX is a two-component torsion spring with “stretchable” design, compact and flexible. This new contact element provides highest performance and low-loss energy transfer as all MULTILAM products do. The unique Stäubli contact technology scores with excellent and constant current-carrying capacity as well as minimal transition resistance due to its sophisticated construction technique.
Stäubli’s demanding quality tests guarantee extremely durable and reliable electrical contact solutions. Therefore, all MULTILAM products from Stäubli provide dependable long-lasting operation.
The design of the ML-CUX contact element allows for installations with very little space. Based on its features and functionality, fewer contact elements are required for the same or higher power, enabling a more compact system design with less heating. For its latest series of innovative high voltage GIS products, Xi’an XD High Voltage Apparatus has successfully implemented the new MULTILAM flexo ML-CUX contact elements in various highly demanding busbars.
By using the latest contact technology novelty by Stäubli, Xi’an XD High Voltage Apparatus increases the innovation level of its GIS portfolio.
The functionality, the excellent, constant and long-life performance as well as the product dimension fully convinced the experts at Xi’an XD High Voltage Apparatus. Thus, their customers benefit from compact, reliable and powerful GIS switchgear equipment, and on top of a positive impact on their total cost of ownership.
Based on the long-standing, trustful business relationship with Stäubli Electrical Connectors and the many years of excellent experience with Stäubli's MULTILAM contact technology, the evaluation of the new ML-CUX series was a logical consequence.
