Round (Rectangle) Aluminum And Copper Paper Covered Magnet Wire

Paper covered magnet wire is the winding wire and its conductor is made of oxygen-free copper rod or electrical round aluminum rod ,

through a certain specification of the extrusion mould or after drawing wire and annealing treatment,

and then the copper (aluminum) conductor is wrapped on two or more than two layers of insulating paper (including telephone paper, cable paper, high voltage cable paper, turn-to-turn insulation paper).

Paper covered magnet wire is manufactured by applying single or multi-layer of a super flexible Kraft paper, thermally upgraded insulating paper tape spirally around bare or film insulated conductors.

Taping operation is carefully controlled to provide a consistent insulation throughout multilayer build-ups, So that Paper covered magnet wire can satisfied the precise requirements for this type of insulation.

Paper insulation is characterized by outstanding dielectric strength when oil impregnated. Paper covered magnet wire usually have single or multilayer paper over square or rectangular conductors.

Application of Paper Covered Magnet Wire

Paper Covered Magnet Wire is used in oil-immersed transformer and other similar electrical coil windings.

Papers are applied with butt intercalation in the following manners

*2 papers- double butt intercalation- advanced 40-60%.

*3 papers- triple butt intercalation-advance 28-38%.

Papers are lapped in the following manners:

*One paper applied with 47-49% overlap-equivalent to 2 papers.

* One paper applied with 64-66% overlap-equivalent to 3 papers.

*Two papers each applied in one of the above manners.
