Improve installation efficiency

20% smaller panels

Tianjin Qihaixin integrates efficiency in heavy-duty crushers

System integrator Tianjin Qihaixin has managed to reduce panel sizes and installation costs thanks to the many built-in features of ABB’s softstarters such as bypass and EOL.


The challenge

When starting a crusher, root blower or conveyor belt – all considered heavy loads – the starting phase of the equipment is the most crucial part. Tianjin Qihaixin had experienced problems starting the equipment before, requiring them to invest in separate up-scaled equipment just to deal with the heavy loads. Furthermore, as Tianjin Qihaixin used conventional softstarters, external bypass contactors and thermal overload relays had to be used.

The ABB solution

By switching to ABB’s softstarters, benefits were clear and immediate. Featuring built-in bypass contactors and thermal overload relays, Tianjin Qihaixin can reduce its equipment size – saving them both time in installation and money from having fewer products to order and administrate. Furthermore, ABB’s softstarters can be selected to handle heavy-loads, meaning Tianjin Qihaixin could choose the same equipment regardless of the loads’ characteristics. As a direct result from choosing the ABB softstarters, Tianjin Qihaixin estimates reducing both panel costs and space with an impressing 20 percent.
