Product Description

Introducing the high-performance 35kV series oil-immersed distribution transformers by CEEG, renowned for their exceptional low loss, minimal noise, reduced temperature rise, and supreme reliability. These transformers boast a core-hanging free design and guaranteed no oil leakage. Utilizing cutting-edge design software, we meticulously perform electromagnetic calculations, analyzing the transformer's main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, along with short-circuit thermal and dynamic stability. This thorough analysis ensures a robust design margin, guaranteeing the safe and reliable operation of our transformers.

Product Characteristics

1. Innovation at its finest: The transformer integrates advanced core seven-stage temperature control technology.
2. Unmatched durability: The transformer body features a mixed insulation system and premium quality components, promising a design life of up to 30 years.
3. Whisper-quiet operation: Our transformers exceed national standards by reducing noise by an impressive 3 to 5 decibels.
4. Leak-proof design: Utilizing acrylic one-time molded seals, each transformer undergoes stringent fluorescent, positive, and negative pressure leak testing to ensure zero leakage.
5. Enhanced reliability: Equipped with an oil level thermometer, a top-mounted pressure relief valve with a contact, an oil level gauge with a contact for the oil storage tank, and anti-fouling reinforced pure porcelain oil bushings, our transformers are built to perform in heavily polluted environments.
6. Sturdy coil construction: The internal coil structure is supported by a high-quality insulating skeleton, with internal and external braces and chamfered pads ensuring uniform electric fields and enhanced reliability. The self-locking lock nuts on all fasteners guarantee that the product can endure long-distance transportation without loosening or core-hanging issues.
