Configuration​

• The transformer is equipped with a comprehensive set of accessories to ensure safe and stable operation, including:​
• 2-position break switch​
• Drain with sample valve in HV (High Voltage) side​
• Temperature gauge​
• Liquid level gauge​
• Pressure vacuum gauge​
• Pressure relief valve​
• Bayonet fuse & current limiting fuse on HV side​
• 36KV under oil arrester with ISO switch​
• Dedicated grounding terminal matching the H0 grounding porcelain bushing: Ensures tight connection with the bushing, reduces contact resistance, and guarantees continuous and reliable grounding performance.​

Outstanding Product Features​

One of the most significant advantages of this transformer is its 7-level off-circuit tapping range (36200V, 35360V, 34500V, 33640V, 33000V, 32175V, 31350V). This wide voltage range allows the equipment to seamlessly adapt to different grid voltage fluctuations and diverse application scenarios—whether it is for industrial parks with high-voltage demands, commercial centers requiring stable medium-voltage supply, or residential areas with standard low-voltage needs. The off-circuit tapping design ensures safe and convenient voltage adjustment without interrupting the overall power supply, greatly improving the flexibility and applicability of the transformer in complex power grid environments.​

Enhanced Safety via Grounding Porcelain Bushing​

• The dedicated H0 grounding porcelain bushing is a key safety feature, with multi-layer protection:​
• Superior Insulation: High-purity ceramic, ≥1000MΩ resistance (25℃), isolates terminals to avoid short-circuits.​
• Strong Adaptability: Anti-pollution coating, resists harsh elements, stable at -40℃~85℃/≥95% humidity.​
• Reliable Connection: Precision inner hole matches copper terminals, ≤0.01Ω resistance, quick fault current discharge.​
• Long Lifespan: Ceramic (wear/aging-resistant, UL94 V-0), ≥20 years service, cuts maintenance costs.
