In modern buildings and sensitive industrial sites, dry-type transformers are gradually replacing traditional oil-immersed transformers. This type of transformer, which does not use insulating oil, achieves voltage conversion through solid insulating materials, and is particularly suitable for occasions with strict safety and environmental protection requirements.
The most notable feature is the elimination of the risk of oil leakage. The windings are firmly wrapped in insulating materials using epoxy resin casting or vacuum pressure impregnation (VPI) technology. This not only eliminates fire hazards, but also allows the transformer to be installed directly at the load center, eliminating the need for a dedicated transformer room.
Three major technical highlights of modern dry-type transformers:
1. Strong overload capacity, the insulation system heat resistance level reaches H level (180℃)
2. Simple maintenance, no oil quality detection and replacement required
3. The noise level is 10-15 decibels lower than the oil-immersed type
From high-rise building power supply to subway traction system, dry-type transformers are showing their value in more fields. As environmental regulations become stricter and urban land becomes more scarce, this oil-free transformer design will surely be more widely used, driving power equipment to develop in a safer and smarter direction.
