Air, oil tight rigid steel tank prevents oil leakage, infiltration of moisture and water into tank.
Bending or folding is priority in tank construction rather than welding to lessen any possibility
of deterioration of insulation oil.
Many factors are taken into consideration in tank design not only for the air oil security,
but also the physical strength to remain intact against rough handling and transportation.
Thickness of steel material is in accordance with domestic or international standards.
The windings of high-conductivity copper and transposed winding conductors are employed
where appopriate, and designed to reduce to a minimum the out-of balance electro-magnetic
forces in the transformer at all voltage ratios.
The windings and connections are adequately braced to withstand mechanical shocks
and electro-magnetic impulsive forces which may occur during handling,
transportation and service.
The insulation of windings and connections are designed to withstand the abnormal voltage
stresses occuring in power systems. Also, they are not liable to soften, ooze out, shrink or
collapse during service.
Special grade, heat-treated, grain-oriented silicon steels are used to minimize hysterisis. |
