Product Overview & Applications
Overview:The HM-A40 export-type vehicle-mounted intelligent cable fault location system is a high-performance device developed by Goldhome closely follows the development direction of the international power industry and adapts to the rapid development of the power sector, taking the on-site operation and maintenance needs of power cables as the objective. It is integrating a complete set of cable fault testing functions.
The whole system adopts an integrated design. It does not require a dedicated vehicle for export, making it suitable for flexible vehicle selection in the destination country and for portable installation and use.
The complete system complies with the general technical conditions specified in the electric power industry standards of the People's Republic of China, DL/T849.1-2019 to DL/T849.3-2019, for special testing instruments used in power equipment.
Applications:It is used for testing various types of faults in power cables, with functions covering precise testing of faults in power cables, railway cables, airport signal control cables, and street lighting cables.
It capable of testing various main insulation faults of power cables with different voltage levels, cross-sections, media, and materials, including: open circuit, short circuit, low resistance, high-resistance leakage, and high-resistance flashover faults.
Key Features & Advantages
- Full-length measurement of power cables: Accurately measures the total length of power cables, providing an important basis for installation, maintenance, and management.
- Wave velocity calibration: Improves fault location accuracy by calibrating the signal propagation velocity in the cable.
- Based on the multiple pulse principle: Enables pre-location of main insulation faults in various power cables.
- Embedded design with Chinese interface: Ensures stable operation.
- Adopt Distributed control bus technology: with high level of automation, simple operation, and convenient wiring test.
- High-voltage pulse output frequency Controllable: the large impact energy to meet the needs of pre-location and precise pinpointing.
- DC high-voltage output with continuous high current burn-through: Rapidly carbonizes high-resistance fault points (such as water-ingressed cables).
- Stable output of 2048J high impact energy: Particularly suitable for internal faults in high-resistance joints.
- Used for cable withstand voltage testing: Efficiently detects cable insulation performance and potential faults.
- Equipped with grounding protection safety monitoring system, on-site video monitoring system, step voltage protection, and self-check functions: Maximizes operator safety.
- Optional wireless intercom: Enables timely communication between field personnel and vehicle operators for rapid handling of abnormal situations.
