What type of transformer is typically characterized as having a low fire hazard?

A dry type transformer is characterized as having a low fire hazard primarily due to its construction and the materials used. Unlike oil-filled transformers, which use flammable oil for insulation and cooling, dry type transformers rely on solid insulation and air for cooling. This significantly reduces the risk of fire because there is no combustible fluid involved in their operation.

The solid insulation materials are generally non-conductive and have high thermal properties, allowing these transformers to operate safely without the risks associated with flammable liquids. As a result, dry type transformers are often preferred in environments where safety is paramount, such as in buildings, schools, and public facilities.

Choosing dry type transformers not only mitigates the fire hazard but also enhances maintenance accessibility and environmental safety, making them suitable for various applications within urban settings and areas with strict fire safety regulations.
