SYN2015.01 busbar connections: busbar connection, with its high insulation resistance, arc, flame retardant insulation board made of high-strength connection accessories, bolted with insulating sleeve. Busway according to specifications, to meet the overlapping area of ??the bus and asked the bolt holes and bolts of the gap is small, due to increased insulation casing bolts Busway, so the gap is more narrow. So when two row busbar connection mistress, two buses axis must be strictly maintained at a center line, and two busbars and busbar bolt hole insulation panels are perfectly aligned, tighten the bolts when you put on every To turn a bolt force uniform. The purpose is to prevent the insulating sleeve to avoid the effect of the bolt is subjected to shear forces during the installation process caused damage. Deal with it after the busway before installing insulation and installation inspection Yao and Yao compare check whether the installation of quality problems caused by lower busbar insulation.
