CONNECTING FLAGS FOR INSULATOR BUSHINGS

CHARACTERISTICS

250 A – 3150 A

STANDARDS

DIN 43675

UNEL 38137

UNE 20-176

AIR DEHUMIDIFIERS

Air dehumidifiers are transparent envelopes that contain salts of chemically pure silicon oxide (silica gel), with colored indicator.

The air sucked inside the transformer get through these envelopes, due to the thermal contraction of the oil mass.
