Products We Source

High Voltage Detectors

Non-contact voltage detection across a wide range — 600V to 275kV AC. Used by maintenance teams and utility contractors to verify de-energization before working on high voltage systems. We stock and source models covering distribution, transmission, and substation voltage classes.

Live Line Testers and Indicators

Live line testers for 3.3kV to 33kV systems confirm whether conductors are energized before contact. Live line indicators cover 750V to 3000V DC applications. Both are critical personal safety tools for MRO and maintenance operations on live or recently de-energized equipment.

Dead Break Testers

Dead break testers confirm voltage absence on cable terminations and dead break connectors from 2V to 66kV. Essential for switchgear and cable maintenance in utility and industrial environments.

High Voltage AC Test Systems

Portable AC high voltage test systems for cable testing, insulation resistance, and commissioning. Available from 15kV up to 100kV AC output. Used in cable manufacturing, installation, and maintenance applications.

High Voltage DC Cable Test Systems

DC test systems for cable insulation testing and fault location. Models available at ±15kV and ±30kV. Used for medium voltage cable testing in utility, rail, and industrial settings where AC test methods are not suitable.

Wireless Phase Comparators

Wireless phase comparison for 11kV to 132kV systems without direct conductor contact. Removes the need for physical connection between phases during switching operations, reducing risk in live switching environments.

Who Buys This Equipment

Our high voltage test equipment customers are typically maintenance managers, electrical engineers, and MRO procurement teams working in utilities, rail, mining, and heavy industrial facilities. Common sourcing scenarios include replacement of discontinued models, fast-turnaround procurement when standard supplier lead times are too long, and locating equipment for international projects where regional distributors do not operate.
