After three months of process, Sheng Zhongyi Electric Power Technology Co., Ltd. trial production of 12KV grounding switch samples delivered into the West Higher Institute testing center. After understanding that, in addition to the regular frequency withstand voltage, short-time withstand current, circuit resistance and mechanical test, the grounding switch products also need to accept the lightning impact and shutdown test two heavyweight experimental requirements. Through the continuous efforts of the technical team, in September 2012, our company successfully completed the testing task.

SZY-test-2012

Xi'an High Voltage Apparatus Research Institute Testing Center is located in Xi'an City, Shaanxi Province, under the Xidian Group, is currently the most authoritative high-voltage product testing station. Therefore, the product type test report issued by this organization is also the most persuasive report of high-voltage products in the industry.
After a three-month process, the 12KV grounding switch samples made by Shengzhongyi Electric Power Technology Co., Ltd. were sent to the testing center of the Western High-Tech Institute. After understanding, the grounding switch products in addition to the conventional frequency withstand voltage, short-time withstand current, circuit resistance and mechanical test thought, but also need to accept the lightning impact and shutdown test two heavyweight experimental requirements. Through the continuous efforts of the technical team, in September 2012, our company successfully completed the testing task.

The staff of the technical group and the teacher of Xi'an High Voltage Apparatus Research Institute constantly discussed the optimized performance of the products, and learned that the ground switch products are divided into three conventional classifications of 12KV, 24KV and 35KV according to the current situation; however, due to the fact that the market orders tend to be special, such as 40KA current opening in case of 12KV voltage and 50KA current opening in case of 12KV voltage, at present, no domestic manufacturer can meet the testing requirements. However, due to special market orders, such as 40KA current opening in case of 12KV voltage and 50KA current opening in case of 12KV voltage, there is no manufacturer in China who can meet the testing requirements.

To this end, Sheng Zhongyi Electric Power Technology Co., Ltd.'s start-up team of technical staff with the "newborn calf is not afraid of tigers" spirit, after three months of trial production process, in December of the same year to complete the 12KV voltage case 40KA current breaking and 12KV voltage case 50KA current breaking grounding switch product type test report. In December of the same year, we completed the type test report of the earthing switch products.

Through the experimental process of the above two test reports, Shengzhongyi Electric Power Technology Co., Ltd. has fully grasped the various properties of the 12KV grounding switch products and the influence of the relevant supporting parts on the dielectric properties of the products. The three synchronized tests are essential for daily production, as their function affects the closing ability of the product; the finish of the sensor and the flatness of the movable and static contacts can completely affect the lightning impact performance of the product and other situations.

Through the continuous pursuit of quality, Sheng Zhongyi Electric Power Technology Co., Ltd. travels about the unique advantages of 12KV grounding switch products compared with other manufacturers:

Advantage 1, the company's insulation part of the product is produced by the insulation part of Shengzhongyi independent production, to avoid the communication and inspection problems in the procurement process; for some special customized products can be adjusted in a timely manner to the production schedule, to provide better service to customers; for the quality of the product has a further control advantage.

Advantage two, in the product base part of the spring base using cast steel molding, not only to provide excellent strength, but also to avoid some of the use of the conditions of the problem; Example: our early production of the product when the use of plastic or nylon products, due to the use of customers with different geographical requirements, northern customers often happen to be too brittle plastic products lead to return to service.

Advantage three, the auxiliary switch position in the grounding switch installation position compared to other manufacturers of grounding switch has a different change, can make the customer in the installation process is more convenient, but also let the product in the transportation process to reduce a certain harm.

Advantage four, the soft connection of the wire nose is changed to use the copper tube directly socket so that the copper wire does not leak, resulting in partial discharge phenomenon.

Advantage five, the bracket is welded as a whole (compared with separate welding on the market) to strengthen the overall structural strength and dimensional accuracy.
