Mô tả :

Kumwell KZ.ISG100-RW is a voltage limiter designed for overvoltage protection of personnel and equipment in DC and AC rail traction systems. It is recommended to install this limiter between the current return path and non-electrified parts of structures laying adjacent to the rails. In case of overvoltage, KZ.ISG100-RW generates a durable conductive path between the overloaded area and the railway’s substation.
This results in increased current loads that are sensed at the substation, tripping the safety switch and thus protecting personnel and equipment. all overvoltage generated by lightning are effectively limited by internal construction of KZ.ISG100-RW.
