Product Description 

Through the use of its patented Magna-Ply® System as well as improving upon traditional insulating technologies, Rea-Algonquin has become a world leader in the high speed application of insulating papers on copper and aluminum.

Typical tape thicknesses used for wrapping conductor are 2, 2.5 and 3 mil.

Linear Served Paper (LSP) is also available.

Insulations available:

Various types of thermally upgraded paper are available either as 100% kraft or as manila/kraft combinations.  Some of these papers are available creped for extra toughness.  Papers coated with "B" stage epoxies are also available.

Nomex® is a tough, high temperature paper that exhibits excellent physical, thermal, and electrical properties. Nomex® is compatible with transformer oil and most commonly used with varnishes and adhesives in both dry and oil-filled applications.
