Company Profile:
Shanghai Wenlida Electric Co., Ltd (hereinafter "Wenlida") is the largest manufacture base in China, the drafter of the national information industry standard, and the famous provider of voltage stabilizer.

Wenlida has more than ten-year's glorious history. Since it established in 1990, Beijing, Guangzhou, Changchun, Chongqing, Chengdu, Qingdao, Jinan and Suzhou office come into existence successively. In 2009, two new standard workshops and R&D center are established in Shanghai Jiading (37000m2) and Zhejiang Jiashan (45000m2) respectively.

Wenlida has gained public praise for its advanced technology, excellent products, stable quality and first class service. Experienced in research and technology, system design, manufacture craft and products quality has made Wenlida famous in the power supply industry. In 1998, 2005 and 2007, Wenlida becomes the appointed supplier of Haier, ZTE and Huawei respectively. Also, it is the qualified supplier of MITSUBISHI,HITACHI,SIEMENS,DOOSAN,MGE,Hisense and OMRON.

Nowadays, Wenlida is applying itself to the research and manufacture of clean energy, environment protection, energy saving, safety guard products. Based on the "specialized voltage stabilizer", "transformer" and "harmonic active filters", Wenlida will try to become the mordern designer and manufacturer of new power supply.
