HZD1202 Portable Digital Cable Identifier for Live and De-energized Cable Testing

Product Introduction

The HZD1202 Portable Digital Cable Identifier is a professional cable identification instrument designed to accurately identify a specific cable from a group of parallel cables. It is widely used in power construction, cable maintenance, substation operation, and electrical testing applications.

Compared with traditional cable identifiers, the HZD1202 integrates advanced technologies including LCD display, intelligent identification judgment, GPS time synchronization, and digital signal processing. The system consists of a transmitting host, receiving host, test leads, and flexible current coil.

By synchronizing the transmitter and receiver through GPS timing technology, the instrument effectively filters interference signals and improves identification accuracy. The test results are displayed directly on the LCD screen, making operation faster, safer, and more reliable.

The compact structure and portable design allow technicians to easily carry and operate the equipment in various field environments.

Working Principle

The HZD1202 cable identifier works by injecting a periodic single-polarity voltage pulse signal into the cable through the transmitting host.

During testing, the far end of the cable needs to be connected to ground to create a current path. The injected signal generates a return current through the earth, forming a detectable current loop.

The transmitter and receiver use GPS time synchronization technology to precisely control the signal transmission cycle and interval, allowing the system to distinguish the target signal from external interference.

The receiving host detects the direction and characteristics of the current flowing through the cable using the flexible coil. By analyzing the detected signal characteristics, the instrument determines whether the tested cable is the target cable.

Applications

The HZD1202 cable identifier is suitable for:

• Underground power cable identification
• Cable maintenance and repair
• Power distribution network construction
• Substation cable verification
• Cable replacement projects
• Electrical engineering inspection
