Although they are both professional electrical companies, Siemens and Legrand, Simon and other companies have different business priorities. Legrand, Simon and other enterprises focus on terminal product manufacturingSiemens has a layout of energy management solutions and subdivided products from power generation systems, transmission systems to terminals, covering the entire industrial chain of the power industry, while Siemens continues to digitally transform in the field of technology, and has established 20 digital customer application centers around the world for energy management and automation.
 
Siemens Electric entered China very early, in the early 20s began to build power plants in China, in 1984, Siemens established the first high-voltage DC transmission line for China, it can be seen that its professional strength at that time has been very good, so far Siemens socket is also the preferred switch and socket products used by Chinese real estate enterprises, Canton Tower, Beijing Jianwai SOHO are using Siemens sockets.
 
Siemens electrical products are not its main business, so some entry-level socket products are manufactured by Liansu, but Lesso is also a very strong manufacturing group, with more than a dozen production bases across the country, postdoctoral research workstations, CNAS laboratories are also a lot, and product reliability is guaranteed.
 
Siemens sockets are divided into Ruizhi, Haorui, Yuanjing, Pinyi and other series according to the price from high to low, Ruizhi series is the first product with a bezel-less design, with a strong sense of appearance, Siemens Ruizhi series won the 2013 IF Design Award. The large jack spacing of 18mm makes it easy to use, and the materials used for the current carrying parts are also solid and reliable. However, as a high-end series of products, the wiring method and split rear seat of the Ruizhi series double-hole pressure plate are slightly outdated, and it is not as reliable and practical as the saddle terminal and integrated rear seat. The price of Ruizhi five-hole socket is 39 yuan, and the cost performance is acceptable.
 
The new Haorui series has three colors of white, gold and silver, among which the jade glaze white appearance is outstanding, the use of hand-polished molds, the highlight treatment is different, the appearance is warm and soft, and it has a strong recognition in the same price products. Its mounting hole adopts an anti-slip design to increase friction and avoid slippery wire during installation, and the quality is more reliable, and the price is 19.6 yuan.
 
Envision, Pinyi two series for entry-level products, Envision series zero line spacing is larger, the safety is stronger, and its shell flame retardancy is also at the same price of the product is also at the highest level, although the workmanship of the current carrier is more general, but at the price of 12.5 yuan, the overall cost performance is very high, it is worth buying. The appearance of the Pinyi series is square and atmospheric, but the internal structure is slightly weaker than that of the vision, and the price is 10.5 yuan, and the cost performance is average.
