Oil-filled transformers
Utility transformers
Power generation 

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.

Continuously Transposed Cable (CTC) 

Typical Applications
Utility transformers 

Standard Construction 

Individual strands are CDA11000 ETP copper magnet wire conforming to ASTM B-48-68. Each strand is insulated with heavy build Formvar polyvinyl formal) enamel insulation conforming to NEMA MW 18-C. An outer covering of insulated tapes is applied over the transposed conductors to provide mechanical and dielelectric strength. These tapes are normally applied with a butt lap and are registered approximately 30% over the previous layer. The top two tapes are normally applied with a butt intercalated lap of 50%. Standard Insulation is 0.003" (0.076 mm) thermally upgraded creped kraft paper.  

Optional Construction 

  • Cold work hardened strands up to 26,000 psi (180 newton/mm2 ) 0.2% offset yield. 
  • Anneal resistand DCDA 11400 silver bearing copper strands (approximately 55,000 psi [380 newton/mm2] 0.2% offset yield). 
  • "B" staged epoxy coating over enamel insulation. 

Optional Insulations 

  • Inner layers of 0.003" (0.076mm) thermally upgraded 60% hemp/40% kraft paper. 
  • Two outer layers of 0.003" (0.076 mm) thermally upgraded creped kraft paper.
