Product Name : Grade H pre-impregnated insulating material
Base material of grade H pre-impregnated insulatingmaterial is a flexible composite made with polyimide, Nomex or other materials with temp. index over 180℃. It’s phase B pre-impregnated material with thermal upgraded resin after baking process. The product has very high mechanical properties,dielectric and thermal upgraded properties. After winding with copper or aluminum foils, the insulation layers are very solid after heating process.This product is ideal grade H insulating material for layer insulating between foil coils in dry-type transformers, also for other motors and electrical appliance. The standard color is claybank or colorless. Tail-made colors are available.
According to JB/T2197, the model of Grade H pre-impregnated materials for dry-type transformers:
* Base material of polyimide film and Nomex paper:6450（NHN)
* Base material of polyimide film and non-alkali glass fiber fabrics: 6452（GHG)
* Base material of polyimide film and non-woven fiber composite：6453（SHS)
To cure under temp. 100℃ for 4 hours, then increase the temp. to 140℃±5℃ for 6 hours, or under 150±5℃, for 4 hours.
The product should be stored in dry, clean and well-ventilated warehouse under 30℃. The fire, heat sources and direct sunshine should be avoided. The shelf life is recommended to be one year. The longer storage period must be approved by lab test before using.
