M0H 30QG110 M4 27Q130 30q130 M5 Electrical Silicon Steel Sheet CRGO Cold Rolled Grain Oriented Steel Coil for Transformer
Eliminate the air gap between the insulating layer and the outer metal shielding layer. No matter how perfect the processing technology of the metal shielding layer is, the bending deformation, cold and hot effects, etc. in its operation and construction will produce a circular flat air gap between the metal shielding layer and the insulation layer.It provides a moisture and chemicalbarrier, shielding layer for XLPE insulated cables.
