Description
RE-B60 is a professional portable cable fault burn-through tester designed for high resistance and flashover fault pretreatment of 10kV~35kV power cables in power operation and maintenance teams, cable construction companies, industrial enterprises and municipal engineering departments. It strictly complies with DL/T 849.1-2004, GB/T 12706.1-2020 and DL/T 596-2021 standards, adopting high-voltage power electronic constant current technology that quickly burns through insulation defect points and reduces fault resistance to low resistance level, enabling subsequent cable fault locators to achieve accurate fault location.
The instrument delivers 0~60kV continuously adjustable DC output with 600mA maximum short-circuit current and 1kW rated power, covering most medium-voltage power cable fault treatment requirements. It supports three working modes: constant voltage, constant current and automatic burn-through. In automatic mode, it automatically completes the whole process of voltage rise, constant current burn-through and voltage drop, and stops automatically when the fault is burned through, greatly reducing manual operation intensity. It is also equipped with high-precision digital detection unit and LCD curve display, which shows real-time voltage and current changes during the burn-through process, and intuitively reflects the fault state change.

FAQ
Q: What is the function of a cable fault burner?
A: In cable fault detection, high-resistance and flashover faults cannot be directly located by low-voltage pulse method or bridge method due to their high fault resistance. The burner applies DC high voltage to the fault point, breaks down the fault point through arc discharge, and burns the high-resistance fault into a stable low-resistance fault, so that the subsequent cable fault locator can accurately locate the fault point. It is an essential pretreatment step for high-resistance cable fault detection.
Q: What types of cable faults is RE-B60 suitable for?
A: RE-B60 is mainly used for pretreatment of various medium-voltage cable high-resistance faults, including: high-resistance grounding faults with fault resistance greater than 100kΩ, flashover faults that only break down under high voltage, leakage faults with large insulation resistance, and high-resistance faults at cable intermediate joints and terminals. It is suitable for XLPE cables, oil-impregnated paper insulated cables and PVC cables of 10kV~35kV. It can also be used as a DC high-voltage power supply for DC withstand test.
Q: What is the difference between automatic mode and manual mode?
A: In manual mode, the operator manually adjusts the voltage and current, which is suitable for complex fault conditions that require flexible control and DC withstand test. In automatic mode, the operator only needs to set the target current and voltage parameters, and the instrument will automatically complete the whole process of voltage rise, constant current burn-through and voltage drop. It will automatically stop and give an alarm when the burn-through is completed, without manual monitoring, which greatly reduces the work intensity of operators and improves the efficiency of on-site rush repair.
Q: What safety matters should be paid attention to during on-site operation?
A: 1. The equipment must be reliably grounded before operation; 2. Operators must maintain a safe distance from the high-voltage output terminal during operation; 3. In case of emergency, press the emergency stop button immediately; 4. The test must be carried out after confirming that the cable is powered off, and the other end of the cable should be properly guarded to prevent others from approaching; 5. After the test, the cable must be fully discharged before touching.
