Why do we use tapes in Relay & Solenoid coils after winding?

Not just in relays, 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.

The relay or solenoid coil is placed by an operator on a rotating spindle, and the machine automatically applies the required number of turns of insulation tape, secures the end of the tape with a wiping action, and  ejects the  coil from the machine.

This taping machine is ideal for larger batch quantities of coils, with very high repeatability and fast cycle times.

The machine is designed to operate with a wide variety of insulation tapes, including Kapton, Polyester, PEN, PVC, PPS, and most other  woven and non-woven types.

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.


What tape is mostly used for relay coils?

Polyester tape is a rich quality tape. The polyester tape uses include material mainly used for Relays, SMPS transformers and electrical relays for temperature application up to 130°in general-purpose insulation.

Applications of Polyester Tapes

  • Film and foil capacitors
  • Phase and coil – end insulation
  • Very good varnish resistance properties
  • Strengthening of edges for slot
  • Core Layer and final insulations of transformers, SMPS, chalk, coils etc
  • Final wrapping of cast resin capacitors
  • Transformer windings
  • Cable jointing


Other Usages of Taping Machine
  • Mobile Charger Cabinet/ Plastic Box Taping
  • Solenoid coil Taping
  • Relay coil taping
  • Drum core & inductor taping
  • Taflon taping applications
  • USB shell paste protective film taping
  • Contactor Coil taping
  • Small DT and large transformer taping 


More Information
