In what cases is a dry-type transformer suitable?

05-22 2025 | By:

Generally speaking, the operating voltage of a dry-type transformer cannot exceed 220V. The reason is that the current will continue to rise when the transformer is working, so the operating level in the middle of the transmission line is also prone to current increase. If the expansion spacing of the control grid is relatively long, it is easy to cause the commonly used circuit breaker route to be connected incorrectly, and the normally closed circuit breaker route will make the AC contactor unable to open. Due to the continuous increase in working voltage, it is easy to generate some risks. Let’s see what situations are more suitable for dry-type transformers.

First, in the process of the working standard voltage of the switching power supply is higher than 220V, in other words, the working voltage of the switching power supply is not suitable for operation.
Second, in the daily working process, due to some unique reasons, the operating working voltage and the specific power supply voltage will be different, especially in the process of operating the small working voltage of the main purpose, so we must pay great attention.
Third, the switching power supply has no neutral point.
Fourth, some requirements for mechanical equipment in actual work are to operate the switching power supply with insulation layer of the ground insulation layer.
Fifth, in power grids with high short-circuit capacity, cast resin type transformer can also be used to better reduce the storage capacity of short-circuit faults, thereby effectively reducing the risk of operating circuit-breaking arc welding.
Sixth, if the application must be realized in a power grid where the control circuit must be connected between two live and neutral wires, this type of transformer will also be applied.
Therefore, dry-type transformers can be used in the above situations, and must be understood during use.

cast resin dry type transformer are widely used in various industries due to their safety, efficiency, and environmental friendliness. Unlike oil-filled transformers, cast resin distribution transformer use air or resin for insulation, making them ideal for indoor applications, renewable energy systems, and commercial buildings.
