Product Introduction

The HC280E Live Cable Identifier—also known simply as a cable identifier, multifunctional cable identifier, or intelligent cable identifier—is designed to resolve technical challenges related to cable identification for power cable engineers and technicians. By utilizing this instrument, users can accurately pinpoint a specific target cable from among a bundle of multiple cables, thereby preventing severe accidents that could result from inadvertently cutting into a live cable. The cable identification process begins with operations performed at both ends of the cable; it is imperative to ensure the accuracy and consistency of the dual-numbering scheme applied at both ends. The design of this instrument incorporates PSK technology combined with sophisticated algorithms. Regardless of how reliable an on-site worker's memory may be, it can never serve as a substitute for the precise identification capabilities of a professional instrument.

The HC280E Live Cable Identifier features a comprehensive suite of functions, including live cable identification, dead cable identification, AC current measurement, and AC voltage measurement. The system consists of a transmitter unit, a transmitting current clamp, a receiver unit, and a flexible receiving current clamp.

Technical Parameters

Product Features

Transmitter: Transmits signals to the target cable for both energized and de-energized cable identification. It features a built-in high-capacity rechargeable lithium battery, automatic impedance matching, and comprehensive automatic protection. The transmitter is housed in a specialized, integrated toolbox-style casing. Constructed from polypropylene resin with added novel composite fillers via a single injection-molding process, the casing boasts low density while offering superior strength, rigidity, hardness, wear resistance, heat resistance, and insulation properties. The case body is capable of withstanding a compressive load of approximately 200 kg. The main unit features an oversized LCD screen that provides real-time displays of remaining battery power and dynamic indications of the transmitted signal, ensuring all information is visible at a glance.

Transmitting Clamp: During energized cable identification, the transmitting clamp couples the signal generated by the transmitter onto the target cable. The clamp features a jaw opening of Φ105mm. The transmitting clamp is directional; the transmitted signal flows into the cable in the direction indicated by the arrow marked on the clamp.

Energized Identification Mode: The HC280E Energized Cable Identifier utilizes clamp coupling to output pulse-width modulated frequency signals. It transmits four distinct frequencies—625 Hz, 1562 Hz, 2500 Hz, and 10,000 Hz—which are coupled onto the target cable (typically a three-core armored cable) via the transmitting clamp. This process injects a composite pulse-width frequency signal into the cable cores. This signal generates an electromagnetic field surrounding the target cable, which is then detected and identified by the receiver and flexible current clamp. Since the pulse-width frequency signal possesses directional properties, the detection process is also directional.

De-energized Identification Mode: The HC280E Energized Cable Identifier utilizes a direct-connection method to output pulse-width modulated frequency signals. It transmits two specific frequencies—1562 Hz and 2500 Hz—injecting a pulse-encoded current signal directly into the cable cores. This current generates an electromagnetic field around the target cable, enabling the receiver and flexible current clamp to detect, decode, and identify the cable. As the current flow is directional, the detection process is likewise directional. Receiver: A handheld device featuring a 3.5-inch color LCD screen and a built-in high-speed microprocessor. Utilizing precise algorithms, it identifies and decodes the pulse-encoded current signals transmitted by the transmitter. It also incorporates a signal strength calibration function, displaying both signal intensity and detection results in a sophisticated and intuitive manner. A dynamic color bar graph provides a clear, at-a-glance visual display; a checkmark (√) indicates successful identification of the target cable, while an "X" marks non-target cables, enabling rapid and automatic identification of the intended cable. Additionally, the device supports a voltage measurement range of AC 0.00V to 600V (50Hz/60Hz), an AC current measurement range of 0.00A to 5000A (50Hz/60Hz), and a measurable current frequency range of 45Hz to 70Hz.

Flexible Current Clamp: A Rogowski coil-based sensor featuring exceptional transient tracking capabilities, allowing it to rapidly identify the pulse-encoded currents generated by the transmitter. It is ideally suited for use with thick cables or conductors with irregular shapes. The clamp features an inner jaw diameter of approximately 200mm, capable of encircling cables up to Φ200mm; this enables non-contact measurement without the need to disconnect the circuit under test, ensuring a safe and rapid operation.
