6kv-34.5kv/120V-600V 5kVA-500kVA Power Distribution Transformer Single Three Phase Pole Mounted Distribution Transformer

Uses high-quality mineral oil/natural ester vegetable oil as dual insulation and cooling medium, removes heat through natural circulation or forced air cooling

Adopts corrugated tank + vacuum oil filling process, eliminates traditional oil conservator, realizes fully sealed operation, prevents moisture and impurities from entering

Integrates a full set of protection devices including gas relay, pressure relief valve, oil temperature indicator and oil level gauge, automatically alarms or trips in case of faults

The breakdown strength of oil-immersed insulation medium is much higher than that of air, can withstand higher lightning impulse and switching overvoltage

Fully sealed design eliminates the need for regular oil change, oil filtration and insulating oil testing, only requires a simple appearance inspection every 10 years

Provides biodegradable natural ester vegetable oil insulation option with flash point higher than 300 C, fire performance close to dry-type transformers, and can be naturally decomposed after disposa

For high-latitude and high-altitude cold regions, provides transformer oil with ultra-low freezing point of -45 C, ensures the transformer oil does not solidify and has good fluidity in extremely cold

Large-capacity transformers adopt split transportation structure of tank and core body, reducing transportation weight by 40%, can be transported by ordinary roads

Excellent heat dissipation performance enables the transformer to operate continuously for a long time under 150% rated load, with short-term overload capacity up to 200%/30 minutes
