Product Overview
Fiberglass Wrapped Wire(Coper/Aluminum)is made by Copper or aluminum conductor evenly wrapped with three or more layers of non-alkali fibreglass.Then it is impregnated incompatible insulating coating of required thermal class,baked to make a whole between fibreglass and conductor.
The product has voltage breakdown resistance, more than three grades temperature resistance, insulation thickness can be customized according to customer requirements, widely used in reactors, transformers, motors or other similar electrical products winding.
Product Material
Aluminum flat wire should meet the requirements of GB5584.3-2009, and the resistivity at 20℃ is not more than 0.0280Ωmm2/m
Copper flat wire should comply with the provisions of GB5584.2-2009, and the resistivity at 20℃ is not greater than 0.017241Ωmm2/m
