The traction disconnectors are outdoor devices used for switching purposes in electric traction systems of all kind of public transport (such as tramways, troleybuses), in both railway and railway siding systems. Or they are intended to be mounted in powering centres and other points of a DC 3kV electrical traction, and to serve there as section switches and section disconnectors/earthing switches.
The QAV and EQAV traction disconnectors are outdoor devices used for switching purposes in electric traction systems of all kind of public transport (such as tramways, troleybuses), in both railway and railway siding systems.
The QAD, QADZ and QADZI disconnectors are used in single-phase DC and AC traction lines and feeding stations of 600 V, 750 V, 1500 V, 3 kV and 25 kV. They allow a disconnection of circuit under load, in emergency situations. The disconnectors can be operated by electric motors or hand operated drives.
The QAD-A disconnectors are used in single-phase AC traction lines and feeding stations of 17,5 kV. They allow a disconnection of circuit under load, in emergency situations. The disconnectors can be operated by electric motors or hand operated drives.
