Technical Comparison

Why Engineers Specify This Model

"The LQTT-50/10 solves a critical challenge: bringing lab-grade 50kV testing to field sites. Its 40kg weight and duty-cycle design enable:

• Mountain-top substation commissioning

• Offshore platform cable tests

• Mobile laboratory operations
  Where traditional HV test sets are logistically impossible."
