Delivery Specification:
PPI 1091 and PPI 10912 are specially formulated shielding tapes comprising a laminate of polyester - copper - polyester. The polyester is
available in thicknesses of both 0,025 mm = 1 Mil and 0,050 mm = 2 Mi l so that the dielectric strength required can be achieved.
PPI - 1091 all widths from 6mm = 1/4 inch
PPI - 10912 fringed all widths from 12 mm = 1/2 inch
Roll length up to 100 metres = 110 yds
PPI 1091 shields the entire inner width of the transformer spool whereas PPI 10912 offers even greater security because of its fringing on
both edges which ensures complete insulation of the spool ends.
PPI 1091 and PPI 10912 are applied directly between the primary and secondary windings and the lead can be point soldered to the
copper foil through the polyester film. The solder point should then be covered with a PPI self-adhesive insulating tape.
