Product Description
505DS live cable identification instrument, also known as cable
identification instrument, multi-function cable identification
instrument, and intelligent cable identification instrument, is
designed for power cable engineers and cable workers to solve the
technical problems of cable identification. The user can accurately
identify one of the target cables from the multiple cables through
the instrument, so as to avoid accidentally sawing the live cables
and causing serious accidents. The cable identification starts from
the operation at both ends of the cable. The double numbering at
both ends of the cable must be ensured to be accurate. This
instrument is designed with PSK technology combined with precise
algorithms. No matter how reliable the memory of on-site staff is,
it cannot replace the recognition of professional instruments. This
product also has the functions of live cable identification, power
failure cable identification, AC current test, and AC voltage test.
It is composed of a transmitter, a transmitting current clamp, a
receiver, and a receiving flexible current clamp.
Transmitter: It transmits signals to the target cable during the identification
of live cables and power-off cables. Built-in high-performance
rechargeable lithium battery, automatic impedance matching, and
automatic protection. The transmitter adopts an integrated special
toolbox design, uses polypropylene plastic as raw material, and
adds new composite fillers for one-time injection molding. It has
low density, strength, rigidity, hardness, wear resistance, heat
resistance, and insulation performance. The cabinet can withstand a
pressure of about 200kg, the host's large LCD displays the
remaining battery power in real time, white backlight, and dynamic
indication of the emission signal, which is clear at a glance.
Transmitting clamp: When the live cable is identified, the transmitting clamp couples
the signal from the transmitter to the target cable. The jaw size
is Φ120mm. The transmitting clamp has directivity. The transmitting
signal flows in from the direction indicated by the arrow on the
transmitting clamp. During live identification: use calipers to
couple output pulse currents, emit four frequencies: 625Hz, 1562Hz,
2500Hz, 10kHz, couple to the target cable (target cable is a
three-core armored cable) through the transmitter, and inject
composite pulses into the cable core Current signal, the pulse
current generates an electromagnetic field around the target cable
for the receiver and flexible current clamp to detect and identify;
because the pulse current is directional, the detection is also
directional.
When power failure identification: Directly connected output pulse current is used to inject pulse
encoding current signal into the cable core. This current generates
an electromagnetic field around the target cable for the receiver
and flexible current clamp to detect, decode, and identify; because
the current has directivity, so Detection is also directional.
Receiver: It is a handheld device, 3.5-inch color LCD screen, built-in
high-speed microprocessor, combined with precise algorithms, to
identify and decode the pulse code current signal of the
transmitter, and has a signal strength calibration function to
display signal strength and detection results. Exquisite and
intuitive; dynamic display of color scale bars, clear at a glance,
successful cable identification check mark, non-target cable check
mark, can quickly and automatically identify the target cable. At
the same time, the testable voltage range is AC 0.00V~600V
(50Hz/60Hz), the measurable AC current range is AC 0.00A~5000A
(50Hz/60Hz), and the measurable current frequency is 45Hz~70Hz.
Flexible current clamp: It is a Rockwell coil with excellent transient tracking ability,
can quickly identify the pulse code current generated by the
transmitter, and is suitable for thick cables or irregularly shaped
conductors. The inner diameter of the jaw is about 200mm, and it
can clamp cables below Φ200mm, without disconnecting the tested
circuit, non-contact measurement, safe and fast.
Special note: This cable identification instrument has both live cable
identification and power failure cable identification functions.
When power failure cable identification, it is strictly forbidden
to connect to the live cable. Live cable identification is only
applicable to three-core armored cables. When identifying, the
transmitting clamp and receiving clamp cannot be mixed, and the
direction of the input signal must be consistent.
