Ss304 Distribution Transformer Oil Type 167KVA 4160V Oil Immersed Transformer
Leilang Electric, a leading manufacturer of industrial power distribution equipment with over 15 years of expertise in transformer technology, presents our premium 167KVA single-phase submersible oil-immersed distribution transformer engineered for underground vault installation. This transformer is purpose-built to deliver reliable power in harsh underground environments, featuring a primary voltage of 4160GrdY/2400V and a secondary voltage of 240/120V (L-N) at 60Hz frequency.
- 304 Stainless Steel Construction: The entire tank, housing, and hardware are fabricated from marine-grade 304 stainless steel, providing exceptional resistance to soil corrosion, moisture, and floodwater damage. The fully sealed welded structure minimizes sealing points, ensuring safe operation even during extended flooding conditions.
- DOE 2016 Energy Efficiency Certified: Independently tested and verified to meet or exceed U.S. Department of Energy 2016 energy efficiency standards, achieving an impressive 99.33% full-load efficiency. This translates to significant long-term energy savings and reduced operational costs for utility and commercial applications.
- ANSI/IEEE Industry Compliant: Manufactured in strict accordance with ANSI/IEEE C57.12.00 and C57.12.20 standards, ensuring compatibility with North American power distribution systems and adherence to global safety regulations.
Equipped with high-conductivity copper windings, Class E insulation (120°C/248°F), and ONAN self-cooling technology, this transformer delivers stable performance with a 65°C temperature rise and a low 55 dBA sound level. It features a 2.75% impedance rating, K-1 harmonic mitigation capability, and a 30KV secondary BIL rating for enhanced electrical protection.
All Leilang Electric transformers undergo rigorous quality control processes, including performance testing at every production stage and comprehensive final inspection. We hold CE and ISO 9001 certifications, demonstrating our commitment to manufacturing excellence. We support sample orders for quality verification, offer full OEM/ODM customization services, and maintain a monthly production capacity of 1,000 units to meet project timelines. All products come with a 24-month warranty from the bill of lading date and lifetime technical support from our team of certified electrical engineers.
