A50 Trolley-Mounted Cable Fault Test System
Couldn't load pickup availability
The A50 Trolley-Mounted Cable Fault Test System integrates TDR pre-location, HV conditioning, and pinpointing into one deployable rig — factory direct at $29,900.
What Is the A50 Trolley-Mounted System?
The A50 bundles TDR pre-location, HV conditioning, impulse generation, and acoustic-magnetic pinpointing into a rugged trolley with tow handle and casters. It deploys in under 10 minutes on site. This all-in-one design cuts fault response time from days to hours.
Why Choose a Trolley-Mounted System?
Portable cases require setup and connection time at each site; a trolley system is pre-integrated and rolls out ready to use. For utilities covering a regional network, the A50's sub-10-minute deployment reduces time-to-test on every outage. The lockable compartments keep all tools secure between sites.
What Are the System's Key Specifications?
The A50 covers 380V–500kV (configuration dependent) with a 0–100 km TDR (±0.5 m) and an integrated HV supply up to 32 kV (upgradeable). Its impulse generator delivers up to 2,048 J. System weight is about 130 kg on the trolley frame.
How Does the A50 Compare to Portable Kits?
A portable kit ($16,000–$28,000) requires module setup at each site; the A50 trolley ($29,900) eliminates that step with a pre-integrated rig. For teams responding to frequent faults, the setup-time savings justify the higher price. The A50 also serves as a training and demonstration unit for utility centers.
