  High voltage motors

  High frequency transformers
  

Product Description
Thermal Class:  200° (copper)

Resistant 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.
Improved insulation protection against transient spikes, high frequencies, elevated voltage levels, and short rise time pulses without increasing insulation thickness.
Excellent resistance to thermoplastic flow (cut-through), abrasion and heat shock.
Excellent resistance to heat and solvent shock conditions encountered in varnishing and encapsulating processes.

Thermal Class: 200

Shape: Round

NEMA Specification: MW 35-C

TYPICAL APPLICATIONS

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

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.
