Multi-voltage capacitor section

The method of making a dual metallized film capacitor section which comprises:

• providing a supply of a first dielectric film strip metallized on one side thereof;
• providing a supply of a second dielectric film strip metallized on one side thereof;
• winding said first and second strips in substantially cylindrical form with the non-metallized side of each strip in contact with the metallized side of the other strip, the metallized edge of said first strip being exposed at one end of said cylindrical form and the metallized edge of said second strip being exposed at the other end of said cylindrical form;
• removing the metallized layer form at least said first strip over a region intermediate the ends of said first strip to thereby form first and second capacitors including respective first plates separated by said region;
• inserting between said region and said second strip a sheet of insulating material positioned to extend outwardly from said one end of said cylindrical form and a length sufficient to encircle the circumference of said form at said region at least once;
• and inserting and winding supplemental dielectric strips into said cylindrical form adjacent the first and second dielectric strips of one of said first and second capacitors.

The method of making a dual capacitor section which comprises:

• providing supplies of first and second dielectric strips;
• providing supplies of first and second metallic strips;
• winding said first and second dielectric strips interleaved with said first and second metallic strips in substantially cylindrical form;
• interrupting said first metallic strip intermediate its ends to thereby form with said second metallic strip first and second capacitors;
• inserting between said first and second dielectric strips adjacent the interrupted region of said first metallic strip a sheet of insulating material positioned to extend outwardly from one end of said cylindrical form and of a length sufficient to encircle the circumference of said form at said region at least once;
• and inserting and winding supplemental dielectric strips into said cylindrical form adjacent the first and second dielectric strips of one of said first and second capacitors to thereby vary the voltage ratings between said first and second capacitors.
