Nomex®/Mylar® insulating pipes, shrinkable, class F (155 °C)

€0,00

Wound Insulation Tubes for use in lacquer-impregnated electric motors with temperature class F.

Reliable fixation due to shrinkage of 35%.
Inner diameters from 2.50 mm to 8.00 mm with wall thicknesses from 0.24 mm available
Rapid shrinkage within 10
Excellent dielectric strength and impact resistance.
Insulating pipe made of five layers of Mylar®/Nomex® for applications with temperature class F and continuous temperatures of up to 155 °C.
The materials are UL recognized

The Mylar®/Nomex® insulating tube insulates and secures electrical connections in electric motors and other applications. Due to its high dielectric strength and impact resistance, this shrinkable insulating tube can also be used in demanding applications at short-term temperatures of up to 160 °C.
