ChinaKey features
Dual Detection Precision: Accurately identifies short-circuit and earth faults up to 1200A to prevent false triggering from inrush current.
Zero Power Disruption: Live-line clamp-on mounting lets teams install units with standard insulated hot sticks without shutting down the grid.
8+ Years Service Life: Built-in lithium battery with ultra-low power consumption (<10uW) guarantees over 5000 cycles without replacement.
All-Weather Grid Monitoring: High-visibility red mechanical flag and flashing LED ensure clear fault location day and night from -35C to +70C.
Durable Polymer Housing: UV-resistant and anti-aging body offers superior weatherproofing compared to standard plastic indicators on overhead lines.

Product Q&A
Q:What is the primary function of the CBDL series fault passage indicator?
A:
It detects and indicates short-circuit and single-phase earth faults on overhead distribution lines (6kV to 35kV). It helps maintenance crews quickly pinpoint fault locations via mechanical flags and LED lights without manual line patrols.
Q:Can these indicators be installed on energized lines without power interruption?
A:
Yes. Designed with a live-line clamp-on mounting mechanism, the indicator can be easily installed or removed on energized conductors using standard insulated hot sticks, ensuring zero power disruption.
Q:How does the indicator prevent false alarms from inrush current or load switching?
A:
It utilizes dual-detection logic combining transient current feature analysis with physical molding detection, along with adjustable action response times (0.06s to 3s) to effectively filter out false triggers.
Q:What conductor sizes and voltage levels are supported?
A:
The indicator supports overhead lines from 6kV to 35kV with continuous load currents up to 1200A, accommodating conductor cross-sections ranging from 16mm2 to 240mm2.
Q:What is the battery lifespan and power consumption?
A:
Powered by a high-energy lithium battery with ultra-low static power consumption (<10uW), it offers an operating lifespan of over 8 years without requiring battery replacement.
