The surface of the aluminum foil used for transformers is smooth and without traces, which can be seen in a clear mirror. The resistivity is less than or equal to 0.028. Packed in moisture-proof paper, with a paper sleeve in the middle. Aluminum foil for transformers is mainly used in large transformers, solar energy, and power industries.
Appearance quality of aluminum foil for transformer:
The section of the aluminum foil is neat, clean, free of burrs, cracked edges, clip edges, towers, loose coils, die string out, arrows, string layers, lifting bars, bumps and other defects, and the welding is firm.
Surface quality of aluminum foil for transformer:
The aluminum foil surface is flat. The surface of the aluminum foil is clean, without corrosion marks, oil marks, wrinkles, slits, scratches, light and dark lines, rubber roll marks, vibration marks, twill marks, etc. There are no bright spots, roll marks, grinding wheel marks and black lines on the surface of the aluminum foil. The surface of the finished aluminum foil has no yellow oil spots, oil sticking, blistering and tearing formed by the burning of lubricating oil.
Transformer packaging with aluminum foil:
There are large roll packing and wooden box packing.
Large roll packaging: The width and length of the roll determine the size and specification of the large roll according to the customized width and length.
Wooden box packaging: approximate size of the wooden box: 1.4 meters long, 1.3 meters wide and 0.8 meters high. The customer's requirements for the width of the aluminum foil and the diameter of the roll are the decisive factors for the size of the wooden box.
