Mylar®/Nomex® End Caps, shrinkable, class F (155 °C)

€0,00

 

Cost-effective insulation of wire ends in lacquer-impregnated electric motors of temperature class F

 

  • Reliable fixation due to shrinkage of 35%.
  • Available with inner diameters from 2.50 mm to 65 mm and wall thicknesses from 0.240
  • Fast shrinking within 10 seconds.
  • Excellent dielectric strength and
  • Structure made from a five-ply composite of Dupont™ Mylar® and Nomex®
  • The foil si UL approved.
  • Resistant to most oils and refrigerants.
  • Suitable for applications in temperature class F at
  • Continuous temperatures of 155°C..

 

The shrinkable Mylar®/Nomex® End Caps insulate and secure electrical connections in electric motors and other applications. They have a high dielectric strength and impact resistance and are also suitable for demanding applications in temperature class F. They can also withstand temperatures of up to 160°C for short periods. By attaching End Caps, short circuits caused by wire residues can be avoided. They are mainly used in the windings of encapsulated and open electric motors.
