Product Description

Product Description

The Cable Line Fault Indicator is an intelligent device designed for rapid localization of short-circuit faults in power lines. It is widely used in box-type substations, ring main units (RMUs), cable branch boxes, substation incoming/outgoing lines, and feeder branches. The device uses a high-brightness flashing signal to mark the faulted section, enabling maintenance personnel to quickly pinpoint the issue, significantly reducing outage investigation time and improving power supply reliability and grid operational efficiency.

Key Features

1. Highly Adaptive Design

   • Constructed with high-strength, weather-resistant engineering plastic housing, offering waterproof and corrosion-resistant properties for stable long-term operation in harsh environments (extreme temperatures, humidity, etc.).

   • Compatible with a wide range of cable or overhead line diameters (5-30mm).

2. Intelligent Reset Function

   • Automatic Reset: Automatically resets after fault clearance based on preset timing or instantly upon power restoration.

   • Manual Reset: Equipped with a manual reset button for flexible field operation.

3. Accurate Fault Detection

   • Detects short-circuit faults based on current surge principles, unaffected by load fluctuations to prevent false triggering.

   • Highly visible flashing indicator ensures quick identification day or night.

4. Long-Term Maintenance-Free Operation

   • Sealed, integrated design ensures reliable performance with minimal maintenance, reducing operational costs.

Application Benefits

• Faster Fault Repair: Rapid fault section localization minimizes inspection scope and accelerates grid recovery.

• Enhanced Power Supply Reliability: Reduces outage impact, ensuring continuous power for end-users.

• Smart Grid Integration: Supports fault location for distribution automation systems, facilitating smart grid development.
