33 кВ масляный распределительный трансформатор1

Liu Gao is a supplier of oil-filled transformers that conform to IEC standards. Our transformers feature a high-quality cold-rolled silicon steel core with a full-fillet non-damaging structure, and are wound with high-quality oxygen-free copper. The transformer uses a radiator-type oil tank made of corrugated sheet or an expansion type tank. Because the transformer does not require an oil expansion tank, its height is reduced and the oil does not contact with air, slowing down its aging and extending the service life of the oil-filled transformer. This product is widely used in the reconstruction of urban power grids, residential areas, factories, high-rise buildings, mines, hotels, shopping centers, airports, railways, oil fields, docks, highways, and other open spaces. Operating environment: 1. Maximum ambient temperature: +40℃ 2. Minimum ambient temperature: -25℃ 3. Altitude: less than 1000 meters 4. Maximum average relative humidity per month: 90% (at 20℃) 5. Installation location: suitable for installation in areas free from fire and explosion hazards, significant pollution, chemical corrosion, or excessive vibration, both indoors and outdoors. Product features: 1. The oil-filled transformer has excellent heat dissipation and significant overload capacity. It can operate without a fan for a long time under 130% overload, maintaining full load without forced cooling under IP45 conditions. 2. The oil-filled transformer provides complete safety and fire resistance, able to withstand long-term burning at 800ºC without smoke emission. 3. The transformer has high thermal shock resistance and can be loaded immediately at -50ºC. 4. The oil-filled transformer is completely waterproof and hermetically sealed to increase durability. 5. The absence of partial discharges ensures a high level of operational integrity for the oil-filled transformer. 6. Due to its good hydrophobicity and resistance to alkaline corrosion, the oil-filled transformer is reliable in various environmental conditions. The oil-filled transformer is environmentally friendly, operates with low noise levels, does not emit harmful gases, and easily decomposes. This product is a great option for those looking for reliable and safe transformers.
