Insulation performance of plum coupling

　　Plum coupling主要适用于起动频繁、正反转、中高速、中等扭矩和要求高可靠性的工作场合，例如：冶金、矿山、石油、化工、起重、运输、轻工、纺织、水泵、风机等。工作环境温度 -35℃～+80℃，传递公称扭矩25～12500Nm，许用转速1500～15300r/min。

　　The plum blossom flexible coupling has good electrical insulation properties and the following characteristics:
　(1) The plum blossom coupling has greater axial, radial and angular compensation capabilities.
　(2) The plum blossom coupling has simple structure, small radial dimension, light weight and small moment of inertia, suitable for medium and high speed occasions.
　(3) The plum blossom coupling works stably and reliably, with good vibration damping, buffering and electrical insulation properties.
　(4) The plum blossom coupling does not need lubrication, the maintenance workload is small, and it can run continuously for a long time.
　(5) The high-strength polyurethane elastic element of the plum coupling is wear-resistant and oil-resistant, has a large bearing capacity, a long service life, and is reliable.
