Market: PTD Power transmission and distribution
MULITLAM flexo ML-CUX
Application: Gas Insulated Switchgear
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.
Experts for advanced high-voltage equipment
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.
Pluggable connections in switchgears
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 energy market’s requirements
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.
Excellent performance for higher productivity
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 w
