The cable monitoring device type 8531 is suitable for insulation monitoring of cable systems used for traction current supply of direct current railways and trolley busses with nominal voltages of up to 750 V. The cable monitoring device operates without external voltage supply.
This cable monitoring device can be used to monitor cable systems for the traction power supply of DC urban rail systems and trolleybus systems with nominal voltages up to DC 750 V (other voltages on enquiry).
The cable monitoring device is suitable for monitoring cable systems for supplying the traction current to direct current railways with rated voltages of up to 1500 V (other voltages on request).
The cable monitoring device is intended for the monitoring of cable units to supply power to DC traction current systems with a nominal voltage of DC 2400V (other voltages available on request).
Cable monitoring devices can be as standard or with additional monitoring of the cable shield for breaks.
The test unit is installed in a well insulated housing for easier handling and can be connected to the terminals of the type 8531 cable monitoring unit by means of a cable and plug or else to the terminals of the type 8532 and 8533 cable monitoring units by means of the couplers that are supplied.
