SGB13 dry-type power transformer product features Low loss: the
no-load loss of the product is reduced by more than 20% compared
with the SCB11 product, with excellent energy-saving effect,
economical operation, and maintenance-free. Low noise: The noise
level of the product is more than 10-15 decibels lower than the
current professional standard JB/T10088-1999 "6-220KV transformer
sound level". Low partial discharge: The resin mixture adopts
advanced mixing methods and vacuum film degassing technologies to
make the mixture uniform and eliminate bubbles in the mixture. The
product has only very low partial discharge, which can be
controlled below 5PC.
Characteristics
High mechanical strength: The resin with filler makes the expansion
coefficient difference in the casting body small, the curing
shrinkage rate is small, the internal stress is small, and the
hardness of the cured product is high. In the epoxy resin
encapsulation layer of the inner and outer surfaces of the high and
low voltage coils, there are The prefabricated reinforcing material
has a dense structure like reinforced concrete, so the mechanical
strength is greater than that of pure epoxy resin, and it can
withstand the sudden short-circuit electromotive force without
damage.
Working environment
1. Ambient temperature: -10° C~+40°C
2. Altitude: <1000m
