The surface of Aluminum Foil for transformer is smooth and traceless, which can be seen as a mirror. The edge is chamfered and has no burrs, which is better than the national standard. Resistivity is less than or equal to 0.028. Packed in moisture-proof paper with a middle paper sleeve. Transformer aluminum foil is the key raw material for manufacturing transformer windings, and it is divided into different grades, specifications, and states according to uses. State: O state. O represents the soft state, and numbers can be used to indicate the degree of softness and hardness, and the degree of annealing. The thickness is between 0.016-0.2mm, which is called aluminum foil for transformers.

Aluminum Foil for transformer appearance quality:
The section of the aluminum foil is neat and clean, without defects such as burrs, cracked edges, pinched edges, tower shapes, loose coils, stringing out of tube cores, arrows, stringing layers, bumps, bumps, etc., and the welding is firm.
Aluminum Foil for transformer can make the dry-type transformer have the advantages of small size, light weight, good insulation performance, flame retardancy, no pollution, small partial discharge, moisture resistance, stable and reliable operation, low noise, and low maintenance cost. It is used in high-rise buildings, It is widely used in underground facilities, commercial centers, residential areas, hotels and restaurants, and coastal humid areas.
