ALCONEX WHITE® Products (105° C)


ALCONEX WHITE® is an innovative cellulose-free insulation that is changing the game in fluid filled transformer applications. ALCONEX WHITE® has a thermal rating of 105° C and a dielectric strength of 4,660 volts per mil (in oil).  The ALCONEX WHITE® product offerings are film, meaning they will not become brittle like a paper product. Our customers who choose ALCONEX WHITE® over paper products are experiencing cost savings, reduction in size of unit, and production of more efficient units.

With the new D.O.E. regulations less than a year away, why wait to make the change?  Not only will ALCONEX WHITE® keep you compliant with those regulations, but ALCONEX WHITE® will provide you with ease of use in production and cost savings as a result of reducing the amount of material needed in a coil.

Decreased Size/Increased Power

With ALCONEX WHITE®, engineers have been able to reduce the size of their design. This decrease in size does not hinder performance; with ALCONEX WHITE®, smaller transformer designs actually have increased performance over current electrical insulations used today.

Reduce Production Time and Carbon Footprint

Not only will customers enjoy cost savings on the design of their products, they will also enjoy reducing their production time with ALCONEX WHITE®.

Industry Certification

ALCONEX WHITE® has meet the guidelines in Oil Compatibility ASTM D3455.  ALCONEX WHITE® has also met the long term thermal aging requirements set by the fluid-filled industry in both mineral and hybrid oils.
