It is safe, non-pollution and heavy inflammable, which can be installed directly on the load center with the merits of free maintenance, easy installation, low combined operation cost, low loss and excellent humidity resistance. The transformer can be operated normally under the humidity of
100% and put into operation without drying in advance from breakdown. There also share the properties of low local discharge, low noise and large heatsinking capability, it can be operated with the rated load of 150% under
the forced air cooling conditions. There equipped with perfect temperature protective control system to ensure safe operation of transformer with high reliability. Referring to the operational research of 10 thousand transformers having been put into use, their reliability subindexes have reached advanced
international standards.
