Insulation

Insulation Materials

Insulation is one of the most important qualities that a transformer has, which is responsible for providing better performance when the transformer is operated. In fact, the durability and stability of a transformer highly depend upon the proper utilization of the insulation materials present within it. This means that other than metallic components like silicon steel and copper, there are also other important insulating materials used in power transformers for better functioning. You must get in touch with a reliable transformer manufacturer so that you can rest assured that the transformers you build will be of top-class quality with the best materials, both metallic and insulating, installed within. Now, let us take a look at the list of insulating materials present in a transformer.

Diamond Dot and Kraft Papers

Kraft Paper – 0.13mm to 0.5mm thickness – Full roll or cut to size available.

Diamond Dot Paper – 0.13mm – 0.38mm thickness – Full roll or cut to size available.

Specialty Papers

Transformer Boards (Presspan Boards)

Used in the electrical, mechanical, and thermal designing of transformers, the pressboard is also made up of vegetable fibers that contain huge amounts of cellulose. These pressboards can be moulded into any shape to be used in transformers; the most commonly seen shapes being angle rings and caps.
