Aluminum(Copper) foil shield paper
Aluminum(Copper) foil shield paper is a new shield insulation material which composite by special adhesive and process,and the raw material should be high density insulation paper and high purity aluminum(copper) foil.Aluminum (copper) foil shield paper is mainly used for transformer, mutual inductor and reactor to earth shield, electrostatic shielding layer and Coil conducting layer.This product can improve the distribution of electromagnetic field, reduce partial discharge, strengthen insulation, reduce loss, improve safety and reliability. It’s a new type of shield insulating material for high voltage electrical industry.
Storage:
Store in the dry and clean area which is above ground 300mm.
