China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. proudly introduces its 35kV series oil-immersed distribution transformers. These cutting-edge transformers are designed with unparalleled precision, boasting low loss, low noise, minimal temperature rise, and exceptional reliability. Our advanced design software meticulously handles electromagnetic calculations and evaluates key parameters like main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and both short-circuit thermal and dynamic stability. This ensures a robust design margin, guaranteeing the transformer's seamless and safe operation.
Product Characteristics
- Our transformers are equipped with an innovative core seven-stage temperature control technology, ensuring optimal performance under varying conditions.
- Built to last, the transformer body features a sophisticated mixed insulation system and premium-quality components, designed for an impressive 30-year lifespan.
- Whisper-quiet operation: Engineered to produce noise levels 3 to 5 decibels below national standards, these transformers ensure a quieter environment.
- Leak-proof design: Utilizing high-grade acrylic one-time molded seals, our transformers undergo rigorous fluorescent, positive pressure, and negative pressure leak tests to ensure absolute integrity.
- Unmatched reliability: The transformers come with comprehensive safety features including an oil level thermometer and a pressure relief valve with a contact at the top of the oil tank. The oil level indicator of the oil storage tank uses an oil level gauge with a contact, and the high and low-pressure bushing employs anti-fouling reinforced pure porcelain oil bushing, making it ideal for heavily polluted environments.
- Superior coil support: Inside the coil, a high-quality insulating skeleton ensures uniform electric fields and enhanced reliability. The use of internal and external braces, along with chamfered braces and pads, fortifies the structure. Self-locking lock nuts on all coil axis fasteners hold the components firmly in place, allowing for stress-free long-distance transportation without loosening or core-hanging issues.
