This is newly developed DSL System by POWERLINE. This is a single pole system. Copper strips of high conductivity are used as conductors for high performance. We recommend this for medium size factories installing smaller capacity cranes requiring not more than 140amps. This system is very easy to install and being joint less has less failure rate. Wear and tare is also less which improves life of current collectors' at least by 50%. Smooth running of the DSL ensures best performance of control panels with VVF drives.
