XHSB505B Cable Identifier — Cable Fault Locator产品特性

Accurate and reliable identification.

A large identification jaw suitable for various cables (transmitting clamp Φ125mm, receiving clamp Φ200mm).

Extremely simple operation and clear, intuitive indication.

Main unit and accessories are portable and neat, small and light in weight.

The receiver's received-signal strength is adjustable.

Both live and de-energized cables can be tested.

Recommended Users and Applications

This instrument is dedicated to cable identification — establishing which one among many cables is the target — for both live and de-energized cables. It is especially suited to:

1. Cable-trench inspection and cable-record surveying crews

For confirming the ownership and identity of each cable in dense trenches holding many cables of the same specification, using the intuitive judgement of the meter-needle swing direction.

2. Live-working and no-outage cable maintenance crews

For identifying a live cable with the coupling method — no operation at all is needed on the cable under test and no outage is required (both ends of the sheath must be well grounded).

3. Cable relocation, re-connection and jointing crews

For confirming the target cable with the direct-connection method on de-energized cables before relocation or re-connection, and for working with the mandatory pre-construction spike test after identification.

Working Principle Live cable detection (coupling method)

The transmitter generates a special pulse signal, which is applied through the dedicated transmitting clamp at one point of the live cable to be identified. According to the principle of electromagnetic induction, an induced signal in accordance with the transmitted signal is produced along the cable; on site the high-sensitivity receiving clamp and the handheld receiver are used to detect all the cables, and according to the receiver's indication the cable carrying the applied signal (the live cable to be identified) can be found accurately.

De-energized cable detection (direct-connection method)

The transmitter generates the special pulse signal, which is applied through a connecting line to the cable to be identified. According to the principle of electromagnetic induction, an induced signal in accordance with the transmitted signal is produced along the cable; on site the high-sensitivity receiving clamp and handheld receiver are used to detect all the cables, and from the meter indication the cable carrying the applied signal (the de-energized cable to be identified) can be found accurately.

Instrument Layout

The instrument consists of the transmitter, the transmitting clamp, the receiving clamp and the handheld receiver.

Transmitter panel: grounding terminal (safety grounding of the equipment); output positive (connected to the red output line); output negative (connected to the black output line); charging (DC12V charging port, connect a 12V charger to charge); power switch; gear switch ("I" for de-energized cable identification, "II" for live cable identification); battery indicator (real-time battery level when the built-in battery works); ammeter (instantaneous average output current).

Handheld receiver: an adjustment knob adjusts the received-signal strength (clockwise to increase, counter-clockwise to decrease; it also has a switch function); a BNC connector on the lower side connects the receiving clamp.

Operation Guide Live cable identification — coupling method

No operation at all is needed on the cable under test — simply clamp the transmitting clamp onto the cable.

Both ends of the cable sheath must be well grounded, otherwise the coupling current decreases as the grounding resistance increases.

If both ends of the sheath are not grounded, or the sheath is broken in the middle, the coupling method cannot be used.

When clamping, the arrow on the transmitting clamp must point to the far end of the cable.

The receiving clamp and the transmitting clamp must be kept at least 2m apart.

1.Connect the transmitter output to the transmitting clamp and clamp it onto a suitable position of the live cable, with the clamp arrow pointing to the cable's far end.

2.Turn on the transmitter power switch and select gear "II"; the power light flashes three times and the ammeter needle swings three times at the same frequency, outputting the pulse signal cyclically.

3.Connect the receiving clamp to the receiver and clamp it onto the cable under test.

4.Note that the receiving-clamp arrow points to the cable's far end, otherwise the needle swings oppositely.

5.Rotate the receiver's adjustment knob clockwise; when a "beep" is heard and the indicator light comes on, the receiver is switched on. Set the received-signal strength to a suitable level; only the cable carrying the signal then receives a signal whose swing frequency matches the transmitter's output switching frequency, with a "beep-beep-beep" sound.

6.If the target cable cannot be identified with the coupling method, it is recommended to use the direct-connection method.

De-energized cable identification — direct-connection method

Wiring method 1: connect the red test lead to the cable core (one phase is enough) and the black test lead to ground; connect the far end of that phase to earth (the cable shielding layer and armour are not grounded).

Wiring method 2: connect the red test lead to the cable core (one phase is enough); connect the black test lead to the copper shielding or cable armour; connect the far end of that phase to the copper shielding or cable armour; and check the grounding state of the copper shielding or armour. Identification is affected by the grounding condition of the grounding system and by whether the shielding or armour is intact, so methods 1 and 2 give the most ideal results.

If the resistance of the grounding loop is too large or unreliable, the transmitted signal may fail to load or may cancel out and the result will be poor; adjust the wiring and use method 1 or method 2.

1.Turn on the transmitter's power switch and set the gear switch to "I"; the power light flashes three times and the ammeter needle swings three times at the same frequency, outputting the pulse signal cyclically.

2.Connect the receiver to the receiving clamp and clamp it onto the cable under test.

3.Note the arrow direction of the receiving clamp (the arrow points to the far end), otherwise the needle swings in the opposite direction.

4.Rotate the receiver's adjustment knob clockwise; when a "beep" is heard and the indicator light comes on, the receiver is switched on. Set the received-signal strength to a suitable level; only the cable carrying the signal receives the same-direction continuous three characteristic signals, with the swing frequency matching the transmitter and a "beep-beep-beep" sound.

Precautions

After the cable to be tested is identified, a spike test must be carried out before construction, to ensure safety!

During testing, the receiver's received-signal strength must be adjusted suitably — neither too large nor too small — and must be set at the starting end before the test; it must not be adjusted during the test.

When the receiving clamp is clamped onto the cable under test, make sure the jaws make good contact; dust, gaps or a loose fit will affect signal reception.

If the needle swing is not obvious on site, check whether the receiving clamp has good contact.

When identifying a live cable, if the interference is so severe that the receiving clamp becomes magnetically saturated and cannot receive the signal, it is recommended to use the de-energized method instead.

The instrument can be directly short-circuited for testing.

When the receiver needle-swing frequency does not match the transmitter, or the swing amplitude is too small, the signal is too weak — rotate the adjustment knob clockwise to increase the received-signal strength.

When the receiver needle swings irregularly or not at all, the interference is too strong, or the cable under test is not the target cable.

The instrument can be used indoors and outdoors, but must avoid rain, corrosive gases, heavy dust and high-temperature places. The operator should have general knowledge of electrical equipment or instruments. It is a high-precision instrument and should be protected from strong vibration; repair, care and adjustment should be by professionals. Charge and maintain the transmitter once every 2 months to prevent battery damage.

常问问题

Q1. What problem does the XHSB505B Cable Identifier solve?

It solves the on-site problem of "which cable is the one we are looking for" during power-cable laying, relocation, maintenance and fault handling — especially in cable trenches where many cables of the same specification are laid together — helping to avoid mistakenly sawing or re-connecting the wrong cable.

Q2. How is the identification result judged?

By the direction of the meter-needle swing: only the cable carrying the applied signal receives the same-direction continuous three characteristic signals, the swing frequency matches the transmitter, and a "beep-beep-beep" sound is emitted. The receiving-clamp (and transmitting-clamp) arrow must point to the cable's far end, otherwise the needle swings oppositely.

Q3. What are the main technical parameters?

Identification by meter-needle swing direction; transmitting clamp jaw Φ125mm and receiving clamp jaw Φ200mm; output voltage 150V (gear I) and 250V (gear II); test range 0Ω–1kΩ (direct-connection) and 0Ω–50Ω (coupling); pulse current 0–10A; pulse period 2.75s per cycle; power supply 12VDC lithium battery (transmitter) and size-5 (AA) batteries (handheld receiver).

Q4. What should be noted when identifying a live cable with the coupling method?

No operation is needed on the cable under test; both ends of the sheath must be well grounded (otherwise the coupling current drops as the grounding resistance rises), and if the sheath ends are not grounded or the sheath is broken in the middle the coupling method cannot be used. When clamping, the clamp arrow must point to the cable's far end, and the receiving clamp and transmitting clamp must be kept at least 2m apart.

Q5. What is included in the package?

The package includes 1 transmitter, 1 receiver, 1 charger, 1 red output line, 1 black output line, 1 transmitting clamp, 1 receiving clamp and 2 size-5 (AA) batteries. Within one year from purchase, quality problems are repaired free of charge, and repair and technical service are provided for life.
