The specifications and testing standards of aluminum tape for dry-type transformers winging are:
1. General specifications are:
The aluminum grade are 1060m 1070m 1350 and so on, the temper of transformer aluminum tape is O(soft temper), the thickness 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.3mm, 0.5mm, etc., the normal width is: 50mm, 60mm, 80mm, 100mm, 120mm, 150mm, 300mm, etc. The surface is smooth and has no scratches. The sides can be chamfered (rounded corners, rounded edges), no burrs, better than the national standard. The resistivity is less than or equal to 0.028. The packing is wooden pallet, inner diameter is 300mm or 500mm.
2. Testing standards
Frequency of use: 50/60HZ;
