Product Description

Product Description

Plastic Dipping Copper busbars can meet the requirements for higher power density in high-  power electronic systems. On the premise of maintaining the same conductor  thickness, higher temperature resistance means that it can have a larger  current carrying capacity and the use of more powerful power devices. Other  composite busbars (ROLINX Easy and Perfomance) limit the operating  temperature to 105°C, while the dipping busbar allows the operating  temperature to be increased to 125°C, thus having a unique advantage in  improving the power level of the existing system design. Dip busbars can  achieve long-term work under very high humidity conditions of 85°C/95%RH  through the improvement of technology and materials, instead of the standard  conditions of ordinary products at 55°C/95%RH. According to the different  requirements of the project, customers can choose the corresponding  humidity conditions to choose our products.

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.
