Clear identification of a cable before it is cut or fitted has huge safety implications. Any mistakes here can result in fatal consequences for the cable fitter and may cause outages for the connected customers. The CI cable identification system has been developed to make this work much easier and safer.The system consists of the current impulse generator and the receiver CI RX. This receiver is connected by (AZF 250-CI or AZF 150-CI) flex clamp for decoupling the identification signal. The pulse generator CI TX generates single sawtooth pulses with a peak current up to 100 A and transmits them into the cable being identified. The current flow of these impulses causes an electromagnetic field with a defined polarity around the cable which is received with the flex coupler of the receiver CI RX, automatically synchronised and displayed by the LED scale. The only possible adjustment is the display sensitivity.
