Ultra Light Power Frequency Testing Transformer , AC Withstand
Voltage Test Set , Portable Type
I. Product Description
CQSB series ultra light power frequency testing transformer is
mainly used for power frequency AC o r DC voltage withstand test
for HV electrical equipment,electrical components,insulation
materials by electrical power system, industrial and mining
enterprises,transportation,scientific research units,especially for
field handover,overhauling and preventive field test of small and
medium
power electrical equipment. it works at power frequency50/60Hz. The
HV booster can adopts SF6 insulation or oil insulation or epoxy
resin insulation .
