Product Description

The 35kV series oil-immersed distribution transformers crafted by CEEG are renowned for their exceptional characteristics: low loss, minimal noise, reduced temperature rise, and unparalleled reliability. These transformers are designed with advanced software that executes precise electromagnetic calculations, analyzing key parameters such as the transformer's main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, and both short-circuit thermal and dynamic stability strength. This meticulous design process, verified by computer simulations, ensures a substantial design margin, guaranteeing the safe and reliable operation of the transformer.

Product Characteristics

1. Incorporates innovative core seven-stage temperature control technology.
2. Employs a mixed insulation system with high-quality parts, ensuring a 30-year lifespan.
3. Operates with low noise, achieving a reduction of 3 to 5 decibels below the national standard.
4. Ensures no leakage with acrylic one-time molded seals, and rigorous fluorescent, positive pressure, and negative pressure leak tests.
5. Delivers high reliability, featuring an oil level thermometer, a pressure relief valve with contact on the oil tank's top, an oil level gauge with contact for the oil storage tank, and anti-fouling reinforced pure porcelain oil bushings for high and low-pressure applications, suitable for heavy pollution environments.
6. High-quality insulating skeleton support within the coil: All coils are reinforced with internal and external braces, with chamfered pads ensuring uniform electric field distribution and enhanced reliability. Self-locking lock nuts secure all fasteners on the coil body, allowing the transformer to endure long-distance transportation without loosening or core hanging.
