Mylar® End Caps, shrinkable, class B (130 °C)

€0,00

 

Mylar® End Caps insulate and secure electrical connections in electric motors, refrigeration systems and other applications. They have a high dielectric strength and impact resistance and are also suitable for demanding applications. By attaching End Caps, short circuits caused by wire residues can be avoided. The shrinkable End Caps are mainly used as secondary insulation in windings of encapsulated and open electric motors.
