Superior and Reliable Insulation

Durable Epoxy Insulation having longer service life, has been used for Conductors of “Wilmar Sandwich Busway Systems”. Benefits of Epoxy, such as Resistance to Water, Moisture, Chemicals, and Mechanical Impact besides dielectric strength, flame retardant properties make them preferred choice as insulation materials. While selecting insulation material, we have also given consideration to factors playing vital role in ageing of insulation. Some these factors are electrical (creepage currents, partial discharge, interfacial processes), Chemical, Thermal, Mechanical (Vibration, Shock, Impact), environmental (UV Radiation, Exposure to Salt Fog).
Selection of insulation material has been done carefully by conducting special tests, which included verification of their electrical, mechanical properties, dielectric, impact strength in conditions exposed to heat, cold, humidity, and vibrations to name a few. As insulation plays a vital role in overall performance and service life expectancy of busway system, our above approach reflects our efforts to provide our customers, a product offering excellent performance in harsh conditions for extended service life. Application specific testing and verification of insulated conductors, involving RTI (Relative Thermal Index),
Flammability Rating, maximum and minimum thickness of insulation and its performance under mechanical impacts, have also been done to demonstrate value for customer’s money.
Class “B” (130 Deg C) Epoxy insulation is offered as a standard. To meet requirements of higher insulation temperatures (Relative Thermal Index), Class “F” (155 Deg C) Grade insulation, is also available upon request.
