The invention discloses a connection method of two tubular buses for a wind power tower, which comprises the following steps: firstly, before a first vertical pipe type bus and a second vertical pipe type bus are installed on a wind power tower, installing a flange at the upper end of the second. A technology for connecting tubular busbars and conductors, which is applied in the direction of conductive connection, installation and connection of busbars, etc. It can solve the problems of complex connection of intermediate joints, easy accidents, easy loosening of bolts, etc., and achieves. The purpose of this document is to detail the requirements of Northern Powergrid in relation to the tubular busbar systems and associated fittings detailed within this document. This process, called “jointing,” may be needed to create a longer busbar from shorter, more manageable pieces; or to create a T-shaped tap-off connection from the main busbar. With the proven LD busbar trunking system, Siemens has more than a decade of experience in safe and the demands of wind turbines, is built upon this experience, adding a special, modular design. It is designed to efficiently transport high currents between different components, such as the generator, transformer, and grid connection. Busbars in general are essential in electrical.
