Why do we use tapes in transformer coils after winding?

Not just in transformers, but most coils made of enameled wire have to be better insulated if a turn can touch other turns that have many turns among them.

The problem is the very low insulation that the enamel presents, mostly due to cracks that exist in the enamel (the maximum voltage that an enameled wire will withstand against another wire of the same type is usually lower than 200V).

The insulation provided by enamel is quite enough to insulate two consecutive turns, twenty consecutive turns or even (in some cases) a hundred consecutive turns. But not to insulate much more than this.

So, the tape is used to insulate turns that have too high voltage (between them) to be handled just by the thin a fragile enamel layers over the conductors.

Types of Insulation Tapes used in coil or core taping

Different sorts of electrical protection tape are accessible, each offering novel properties and advantages in light of the particular development material. A couple of the most famous sorts of tape are recorded underneath.

Polyester tape

Constructed of a thin film, polyester tape offers superior electrical, chemical, and mechanical properties. It can be used in a range of service temperatures, standing up against cold weather while providing high heat resistance (-100 °F/-73 °C to over 500 °F/260 °C). Adhesive transfer is minimal. Polyester tape also has high abrasion resistance along with high dielectric strength.

Transformer Insulation Tape

Transformer insulation tape is flame-resistant and can stand up to high heat exposure. This tape offers great adhesive properties and can be used to create a tight coil construction.

Transformer insulation tape is commonly used for:

  • Lead insulation
  • Coil wrapping and banding
  • Dry-type and oil-filled transformers

Black Vinyl Tape

Black vinyl tape is constructed from vinyl film and is coated with rubber adhesives. It is the industry standard due to its optimal weather resistance and UV resistance. Numerous colors are available, and the tape can be removed easily without leaving behind heavy adhesive residue.
