The S20 Cable Identifier safely identifies the correct cable among dozens in shared ducts before cutting or jointing — preventing fatal mistakes — factory direct at $3,600 FOB.
What Is the S20 Cable Identifier?
The S20 is a field instrument that injects a coded signal into a target cable and detects it uniquely at the far end, even among parallel cables. It operates on both live and de-energized cables. The instrument includes AC current and voltage testing capability for comprehensive cable verification.
Why Is Cable Identification a Life-Safety Step?
Cutting or jointing the wrong cable in a shared duct can energize workers or sever a critical circuit. The S20 eliminates this risk by applying a 625 Hz–10 kHz coded signal (live) or 500 V pulse (de-energized) and confirming the correct cable at the work end. Utilities require this verification before excavation or cutting.
What Are the S20's Key Specifications?
The S20 transmits at 625 Hz–10 kHz for live cables and 500 V/5 A pulses for de-energized cables, with an identification range of 0–10 kΩ (de-energized) and 0–100 Ω (live). Its transmitting clamp has a 120 mm inner diameter, and it measures AC voltage from 0.01–600 V and AC current from 0.01–5,000 A.
How Does the S20 Compare to Visual Verification?
Visual inspection and cable records are unreliable in congested ducts — cables shift, records age, and labels fade. Signal-based identification confirms the physical cable path regardless of documentation. The S20's direction-aware detection prevents identifying the wrong parallel cable even when signals couple across adjacent conductors.

Applicable Scenarios
- Shared duct cable verification — identify the correct cable among dozens
- Pre-cut safety check — confirm the cable about to be cut is the intended one
- Switchgear and termination identification — trace cables at substations
- Cross-connection troubleshooting — resolve swapped-phase records
- Mandatory pre-work safety step — required before excavation or jointing
Testing Method
- Isolate the group — confirm access to both cable ends
- Inject the code — connect the transmitter to the target cable
- Probe the far end — use the receiver clamp on each cable
- Identify — the coded-signal cable is the target; others show nothing
- Confirm direction — verify signal flow orientation
- Tag the cable — apply an ID tag for the work crew
- Record — update cable records with the result

FAQ
What is a cable identifier used for?
It uniquely identifies the correct cable among parallel cables in shared ducts before cutting or jointing.
Can the S20 identify live cables?
Yes — the S20 identifies both live cables (625 Hz–10 kHz signal) and de-energized cables (500 V pulse).
How far can the S20 identify along a cable?
Identification works up to 0–10 kΩ path resistance on de-energized cables, covering typical distribution runs.
Why is cable identification required before cutting?
Working on the wrong cable can energize workers or sever critical circuits — identification is a life-safety step.
What is the S20's price?
$3,600 FOB with a 1-year warranty and lifetime maintenance support.
