Product Overview
The XHSB505B Cable Identifier is a professional field instrument developed to solve one of the most persistent challenges in power cable operations: which cable is the one we are looking for? In cable trenches with dozens of cables of identical specifications, construction and maintenance crews face significant difficulty identifying the correct cable. The XHSB505B eliminates this uncertainty with rapid, accurate cable identification using advanced pulse signal technology and high-sensitivity electromagnetic detection.
Developed under the guidance of electromagnetic field theory and utilizing modern electronic and tooling technologies, the XHSB505B is the practical solution for high-voltage cable construction, installation, maintenance, migration, and troubleshooting teams. It uniquely supports both live (coupling method) and de-energized (direct connection method) cable identification in a single portable device.
🔍 What Makes the XHSB505B Different: Unlike conventional single-mode cable identifiers that work only on de-energized cables, the XHSB505B identifies both live and de-energized cables with a simple gear switch — enabling uninterrupted field workflow. Its 15A high-current pulse signal penetrates through cable shielding for reliable detection where weaker signals fail, and the 125mm large jaw accommodates a wide range of cable diameters.

Working Principle
De-Energized Cable Detection (Direct Connection Method): The transmitter generates a special pulse signal that is applied to the target cable via direct connection. According to the principle of electromagnetic induction, an induction signal consistent with the transmitted signal pattern is generated along the entire cable. Using the high-sensitivity receiving clamp and handheld receiver, operators scan all cables on site and accurately identify the signal-carrying cable by observing the receiver meter indication and audible "beep" signal — indicating the de-energized cable to be identified.
Live Cable Detection (Coupling Method): The transmitter generates a special pulse signal applied to the live target cable via a dedicated transmitting clamp — no direct electrical connection required. The induction signal propagates along the cable, and the receiving clamp detects it among all on-site cables. The receiver indicates which cable carries the signal through consistent pointer swing frequency and audible pulses, enabling safe identification of live cables without disrupting service.
Operation Instructions
De-Energized Cable Identification — Direct Connection Method
- Disconnect the cable armor at both ends from ground. Connect the red output clip to the target cable core wire (good phase or higher insulation phase). Connect the black output clip to the ground point or ground stake. The corresponding core wire at the far end must connect to the same ground point.
- Turn on the transmitter power switch, select Gear "I". The power indicator flashes three times and the ammeter pointer swings three times at the same frequency, then cycles pulse signal output.
- Connect the receiver to the receiving clamp, and clamp onto the cable to be tested.
- Ensure the receiving clamp arrow points in the direction of current flow — otherwise the pointer swings in the opposite direction.
- Turn the receiver knob clockwise until hearing a "beep" to power on, then adjust signal strength. Only the signal-carrying cable will show consistent pointer swing frequency matching the transmitter, with audible "beep-beep-beep" pulses.
Live Cable Identification — Coupling Method
⚠️ Coupling Method Precautions:
1. No operation needed on the cable under test — simply clamp the transmitting clamp onto the cable.
2. Both ends of the cable sheath must be well grounded; coupling current decreases with increasing ground resistance.
3. Do not use coupling method if the sheath at either end is ungrounded or broken in the middle.
4. The arrow on the transmitting clamp must point toward the cable end.
5. Maintain at least 2 meters distance between receiving and transmitting clamps.
- Connect the transmitter output to the transmitting clamp, and clamp onto the live target cable at a suitable position.
- Turn on the transmitter, select Gear "II". The power indicator flashes three times and the ammeter pointer swings at the same frequency, cycling the pulse signal.
- Connect the receiver to the receiving clamp, and clamp onto the cable to be tested.
- Ensure the receiving clamp arrow points in the direction of current flow.
- Turn the receiver knob clockwise until hearing a "beep" to power on. Adjust signal strength — only the signal-carrying cable shows consistent frequency swing and audible "beep-beep-beep" pulses.

Frequently Asked Questions
Q1: Who is the XHSB505B designed for?
The XHSB505B is specifically designed for high-voltage cable construction teams, installation engineers, maintenance crews, and field troubleshooting personnel who frequently work in cable trenches with multiple cables of identical specifications. It solves the critical challenge of "which cable are we looking for?" — a problem that plagues cable laying, migration, repair, and fault-finding operations where misidentifying a cable can lead to severe safety incidents and costly downtime.
Q2: How is the XHSB505B different from other cable identifiers?
The XHSB505B stands out in three key ways: (1) Dual-mode capability — it identifies both live cables (via coupling method) and de-energized cables (via direct connection) with a single device, where most competitors handle only one mode. (2) 15A high-current pulse signal provides stronger penetration through cable shielding for more reliable detection. (3) The 125mm large jaw diameter accommodates a wider range of cable sizes. Its intuitive pointer-based indication and audible feedback make it exceptionally easy to use under field conditions.
Q3: Can the XHSB505B identify live cables without interrupting power supply?
Yes. Using the coupling method (Gear II), the transmitter applies a pulse signal through a dedicated transmitting clamp — no direct electrical connection to the cable conductor is required. The signal couples inductively through the cable sheath, allowing safe identification of live cables without shutting down power. This is critical for maintenance operations where service continuity must be maintained.
Q4: What field conditions are required for reliable identification?
For de-energized cable identification (direct connection method): the cable armor at both ends must be disconnected from ground, and the far-end core wire must connect to the same ground point as the transmitter. For live cable identification (coupling method): both ends of the cable sheath must be well grounded — if either end is ungrounded or the sheath is broken mid-cable, coupling method cannot be used. Maintain at least 2 meters between receiving and transmitting clamps. Ensure clamp jaws are clean and making full contact for optimal signal reception.
Q5: What maintenance does the XHSB505B require?
The instrument should be stored away from rain, corrosive gases, excessive dust, and high temperatures. Avoid severe vibration as it is a precision instrument. The transmitter's built-in 12VDC lithium battery requires charging maintenance every 2 months to prevent battery degradation. All repairs, maintenance, and adjustments should be performed by qualified professionals. The instrument comes with a 1-year warranty covering product quality issues, with lifetime repair and technical support available.
