De-energized conductor cable identifier UHV-520

conductor checker

UHV-520 Off-line power cable identification tester is designed to identify a single target power cable among multiple cables to prevent accidents caused by incorrect cutting of live cables. The system combines a battery-powered transmitting host and a color-LCD receiving host to provide clear, multi-criteria identification in congested cable bundles.

Features

• Transmitting host powered by a high-energy lithium battery: no on-site 220 V required; compact, low consumption and multi-level battery indication.
• Receiving host with color LCD showing signal direction, amplitude and interval synchronously; multiple signals are retained on the time axis for improved identification accuracy.
• Flexible measuring coil enables identification where rigid calipers cannot be applied, solving issues from cable congestion and overlap.
• Includes launch caliper for live identification by caliper coupling, allowing both offline and live use with one instrument.
• High-strength ABS protective case for instrument protection and transport in harsh field environments.
