A736

flexible Aramid Insulation Paper

Aratech® A736 aramid insulation paper is a flexible calendered meta-aramid material, It combines stable dielectric performance (13.5 kV/mm) with mechanical strength and flexibility, maintaining integrity under both thermal and electrical stress.
A736 is a cost-effective insulation solution, it can be applied either as a be used independently as a flexible insulating layer or laminated with PET/PI films to form flexible composite insulating materials. With strong resistance to short-term overload conditions, it maintains insulation integrity under peak operating stress. it's suitable for inter-turn, inter-layer, and end insulation in transformers, as well as slot, turn, and shim insulation in motors and generators. ensuring stable performance in F/H-class electrical insulation systems
