Why Choose Our 35KV Oil-Immersed Transformers?

Exceptional Energy Efficiency

Your operational costs matter. Our transformers cut vitality utilization essentially. The no-load misfortune remains at ≤800W for 1000kVA units—that's 10% less than S20 models. You'll spare over 2,200kWh yearly per transformer. Each kilowatt spared deciphers specifically to your foot line.

Built for Requesting Environments

Harsh conditions do not stage these units. The IP67-rated oil tank and C5-M erosion resistance handle coastal salt splash, mechanical contamination, and high-altitude establishments up to 3,000 meters. Temperature extremes? No issue. Our transformers work dependably in open air situations coming to 40℃.

Whisper-Quiet Operation

Noise contamination influences your working environment quality. At ≤50dB(A) for 1000kVA models, our transformers run 8dB(A) calmer than national benchmarks. That's comparable to ordinary discussion levels. Your group and neighbors will appreciate the difference.

Superior Security Standards

Safety isn't debatable. The H+ lesson separator framework withstands temperatures up to 200℃. Lightning drive security comes to 170kV crest. Short-circuit resistance handles 2.5 times appraised current for 2 seconds. Halfway release remains underneath 2pC, guaranteeing long-term unwavering quality.
