 1P801H Three-Layer Polyester Tape "LESS TAPE, MORE INSULATION"
Manufacturers of coils or transformer are set to achieve triple benefits with the new electrical
Insulation tape 1P801H (3 layer) - a triple-layer polyester film tape with flame retardant acrylic
Adhesive.
Not only does the tape offer increased productivity where the US standard UL1950 demands
Reinforced insulation, it also allows for more efficient use of space in the transformer design and reduces overall production costs by using less materials.
Field tests conducted in the US show productivity increases of between 20-40%; made possible by taking away the need to wrap count three times. It is also possible to measure an insulation thickness decrease of around 30-40%. Because the tape is made up of three 0.0125 mm layers of polyester film with pressure-sensitive adhesive all three layers are precisely positioned, automatically. This new adhesive tape is available in 66 Meters rolls in all standard width. Applications : Designed for use as inner-layer insulation on transformer magnet wire windings where reinforced insulation according to UL1950 and /or IEC/EN 60950 is required.

What is OBJT2 ?
Underwriters Laboratories has a category for winding wires called OBJT2 - SPECIALTY
TRANSFORMER WINDING WIRES
This category covers insulated wire for use in transformers which normally do not have
interleaved insulation. The insulation provides basic, supplementary or reinforced
insulation in wound components in class A,E,B,F and H insulation systems using round
winding wire. The normal diameter in this category is .2mm - 1.0mm. Rubadue Wire has
approved from .07mm to 2.5mm
Approval to this standard by definition means that the product is approvewd to the current
edition of UL60950. The current edition of UL60950 is the 3rd Edition, even though there was
no 1st or 2nd Edition that anyone knows of !
The basic standard used to evaluate this wire is the "Outline for Investigation for Special
Transformer Winding Wire", Subject 2353 which is on IEC 60950. Other standards that may be used
are IEC60851; UL746A; and UL60950, Annex U.
Marking - This is a component program listing and the marking required is
manufacturer's identification, catalog model and UL Recognized Component Mark.
