Transformer Insulation

DuPont Electrical Materials for Transformer Insulation

Meet safety standards in transformers that require lead-free soldering and triple insulation conductor wiring.

Transformers used in information technology equipment are required to meet safety standards IEC 60950 and UL60950.

DuPont Electrical Insulation Systems (EIS) can help meet these standards in transformers that require lead-free soldering, in either through hole or surface mounting. For Class B, DuPont Electrical Insulation System, LZ100, RZ110 can be used. For Class F, LZ200, RZ200, DuPont™ Zytel® HTN and Rynite® PET flame retardant grades are available.


  • Zytel® HTN high performance polyamide

    Zytel® HTN is a metal alternative, helping reduce total cost and application weight through part consolidation. Offering high thermal resistance, this versatile polymer improves strength and durability.


  • Zytel® nylon resin

    DuPont™ Zytel® nylon resin provides a comprehensive family of performance grades and properties that range from toughness and stiffness to thermal and chemical resistance.
