Advantages of liquid filled transformers

When it comes to investing in your HV infrastructure, its important to know what your priorities are and work with a provider who can help you to achieve your goals. If your priority is based on lowest first cost, then dry type distribution transformers are often ruled out at an early stage as they typically have higher operating losses than liquid filled transformers. For this reason, liquid filled transformers are often bought for utilities.

Liquid filled distribution transformers are also often utilised in situations where a higher capacity is required as they are noticeably more efficient in this application. Due to their additional cooling and insulation properties, they’re often located in outdoor spaces additionally, the cooling properties of liquid filled transformers are often smaller compared to a dry type transformer of the same rating.
