Thermal Class: 200
NEMA Specification: MW 35-C
Hand wound and high speed windings with difficult insertion and winding characteristics for inverter-driven motors, high frequency transformers, and high voltage motors
FEATURES AND BENEFITS
l Exceptional resistance to voltage stresses generated by high frequency, rapid rise time, voltage spikes typically introduced by IGBT-type inverters. Motor life is increased significantly over standard MW-35C magnet wire under these voltage stresses and across a wide temperature range l Substantial insulation protection against transient spikes, high frequencies, elevated voltage levels, and short rise time pulses without increasing insulation thickness l Enhanced resistance to thermoplastic flow (cutthrough), surface abrasion and heat shock l Enhanced Dielectric strength l Exceptional flexibilty without embrittlement, due to the significant reduction in size of the shield coat particles to the nano level l Excellent resistance to heat and solvent shock conditions encountered in varnishing and encapsulating processes l ROHS & REACH Certified l 100% in-line tested for HVC and bead prevention Availability:

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.
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.

Special purposes tapes, including Kapton® and Mylar®, plus various micas, diamond and epoxy coatings are available by special order.
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.
Thermal Class: 180° (copper)
Magneflex features copper or aluminum conductors insulated with a high temperature engineered resin. The advanced polymer coatings have been very successful in transformer applications.
