On June 18, Shaanxi Zhongqin Power Equipment Manufacturing Co., Ltd, located in Caotan Ecological Park of Xi'an Economic and Development Zone, successfully produced the world's first 1100 KV UHV conductor, and attracted great attention of the industry. Related personnel said that, the successful development of 1100 KV power transmission equipment is a landmark in China's power industry development.
 
In the power transmission project, the 800 KV and above voltage level is known as the UHV. At present, 800 KV voltage level is only successfully developed and produced in Japan and Russia in the world while Italy is still in the test process. It is understood that Xian Electric Engineering Co., Ltd has successfully developed the 800 KV TGCB (tank circuit breaker) and 800 KV GIS (SF6 circuit breakers),and the products have been put into use in the 800 KV station of east Lanzhou. This technology is of leading level in China and an advanced technology in the world, and the company has completely proprietary intellectual property rights. Shaanxi Zhongqin Power Equipment Manufacturing Co., Ltd is the only professional electrical pole providers for the 800 KV electric power transmission project undertaken by Xian Electric Engineering Co., Ltd. It is also the main suppliers to provide key components of other (110 KV-1100KV) conductors, categories and Shell Shields.

To meet the demand of " power transmission from northern to southern China", the State Council and the State Grid Corporation required Xian Electric Engineering Co., Ltd to develop the Southeast Shanxi - Nanyang - Jingmen 1100 KV transmission equipment. Xian Electric Engineering Co., Ltd and ABB Company are responsible for the development and Xian Electric Engineering Co., Ltd has absolute intellectual Property rights. The company further improved the technical precision and requirements on the basis of 800 KV UHV. All the details experienced in-depth analysis and discussion from technology to manufacturing. The companies predictably analyzed the problems which may arise in order to make sure there are no careless mistakes and errors. Each procedure was controlled strictly, each part of data was measured precisely, and all aspects of work had been dealt with in an effort to make the best. Shaanxi Zhongqin Power Equipment Manufacturing Co., Ltd is responsible for the Production of  1100 KV UHV conductor, and finally it has produced the world's first 1100 KV UHV conductor. The test showed that it met all the requirements of the various indicators.
