Product Description

COMPANY PROFILE:
Shanghai Wenlida Technology Co., Ltd (hereinafter "Wenlida") is the largest manufacture base in China. Indeed, Wenlida has more than ten-year's glorious history. Since 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.
PRODUCT DESCRIPTION:
The Laminated Busbar for Industrial, is a multi-layer composite structure connection bar, which can be regarded as the express-way in the power transmission system. Compared with traditional, cumbersome, time-consuming and troublesome wiring methods, the composited laminated busbars can provide a modern, easy-to-design, fast-installation, and structure-clear power distribution system; as same time as, it achieves high current carrying through efficient and compact design, while reducing resistance and electromagnetic interference, improving the performance and safety.
