Product overview

35 kv oil-immersed power transformer is advanced in designing, make great improvement on the material and structure .High and low voltage clamp with steel belt or and side beam taut, form a strong frame structure, strengthen the core clamping force and tolerance transportation capacity. Anti-short circuit ability is strong, beautiful appearance, reliable operation, low loss, low noise, reach the advanced level of the same products abroad. The SZ11-8000/35 one-time through the national transformer prototype testing center for sudden short circuit test, high and low voltage coil set longitudinal oil way is good for heat dissipation, can greatly reduce the copper oil temperature difference and the hot spot temperature rise within the coil.

Execution standard:

GB 1094.1 2 general electric power transformer, power transformer temperature rise,
GB 1094.3 "level of power transformer insulation and insulation test"
GB 1094.5 the ability to withstand short-circuit power transformer
GB/T 6451 "three-phase oil-immersed power transformer technical parameters and requirements"
GB/T 15164 "guidelines for the oil-immersed power transformer load
IEC76 "power transformer"
GB 2536 "transformer oil"

Note 1: transformer with 6300KVA or less rated capacity can provide products whose high-voltage tapping range is ±2×2.5%.

Note 2: 10.5KV and 11KV transformer lower than low voltage can provide products with connection symbol of Dyn11.

Note 3: transformer with 3150KVA or more rated capacity has the greatest tapping current on -5% tapping position.
