Main Products-> closed busbar

Since the first set of metal closed busbar in China in 1978, more than 1000 sets of metal closed busbar and its supporting equipment have been successfully designed and manufactured for large hydropower, thermal power and nuclear power units at home and abroad. The metal enclosed busbar products designed and manufactured by our factory have been running well since they were put into operation, and some of them have been in operation for over 30 years.
But in June 1979, the domestic production of the first unit of 200MW closed bus (Henan Jiaozuo power plant)

But in September 1979, the first domestic production of 225MW hydro generator enclosed bus (Guizhou province Wujiang Du power plant)

But in May 1980, the domestic production of the first unit of 300MW busduct (Jiangsu province Jianbi Power Plant)

But in August 1996, produced the first export of nuclear power units closed bus (Pakistan Chashma nuclear power plant)

But in April 1997, the domestic production of the first unit of 600MW closed bus (Harbin third power plant)

But in December 1997, the first domestic production of 550MW hydro generator enclosed bus (Sichuan province two Ertan Hydropower Station)

The September 1999, the first domestic production of nuclear power generating units of closed bus (Zhejiang province Qinshan nuclear power station two)

But in August 2006, the first domestic production of the highest vertical enclosed bus (Datang Chongqing Pengshui Hydropower Station)

But in November 2007, the first domestic production of 700MW hydro generator enclosed bus (the Yellow River Laxiwa Hydropower Station)

But in August 2010, the first domestic production of 1150MW the maximum current of forced air cooling of eight surface enclosed bus (Guangdong Nuclear Hongyanhe, Ningde)

But in March 2011, the world's first largest production capacity of 1750MW forced air cooling bus (Guangdong Taishan nuclear power project)

Main product advantages

The total cutting of the closed phase busbar conductors with elbow and T joints is (the angle error is 5 ", the geometric size error is 0.02mm).

The vacuum ion plating is used in the joint part of the busbar, which is the advanced technology of silver plating. The adhesion of the coating is strong, uniform, and the welding process is good, which effectively reduces the stability of the contact surface.

Full automatic computer control four roller bending machine. The introduction of the Swedish ROUNDO company, to ensure that the shell roundness, concentricity and conductor

The welding of the large TIG, MIG automatic gas shielded welding equipment imported from Sweden ESAB company

We can produce insulation tube common box bus and have many operating performance manufacturers. The common bus bar has good anti dew, wind and sand protection, and the installation and adjustment is more convenient.
