Oem Power Line Insulator Power Strain Porcelain High Voltage Composite 33kv Post Insulators
Description:
Transformer bushing is to lead high and low voltage inside the
transformer to the outside of the oil tank, not only as a lead to
the ground insulation, but also bears the role of fixing the lead,
transformer bushing is one of the transformer current-carrying
elements, in the operation of the transformer, through the load
current for a long time, in the case of short circuit outside the
transformer through the short circuit current
