aluminum strip for transformer winding -Transformer aluminum strip according to the use of different grades, specifications, status. Brands are: 1060, 1050, 1050A, 1060, 1070, 1070A, 1350, state: O state. O represents the soft state, can be used to indicate the number of hard and soft, and the degree of annealing. Thickness between 0.08-3.00, known as: aluminum foil, foil for dry transformer.

Dry type transformer for aluminum strip and foil made of high quality pure aluminum as raw material, with high conductivity, soft features, smooth surface, no burr, is an ideal material for the production of dry type transformer, is the key material for manufacturing of transformer windings, the aluminum foil conductivity, burr edge, side bending, surface quality and a number of technical requirements is very high.

Dry-type transformer with aluminum, foil generally choose 1060 Aluminum plate, aluminum containing more than 99.6% of the amount is also known as pure aluminum plate, aluminum plate in the family belongs to a commonly used series. The advantages of this series aluminum plate: the most commonly used series, the production process is relatively simple, the technology is relatively mature, the price is relatively high compared with other high-grade aluminum alloy has a great advantage. Has a good elongation and tensile strength, fully able to meet the requirements of conventional processing (stamping, stretching) high formability. For the industrial pure aluminum, high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but the intensity is low, heat treatment can not enhance machinability is not good; can welding, welding and welding with hydrogen atoms, is not easy to bear all kinds of pressure brazing; processing and drawing, bending.

1060O state, with high aluminium content transformer aluminum strip (usually 99.6%-99.7%), and the electrical conductivity and thermal conductivity of aluminum is just below the conventional metal copper, conductive metal as follows: gold silver copper aluminum nickel alloy. Since the price of copper is much higher than that of aluminum, the most commonly used material in the transformer belt is aluminum. Transformer aluminum brand mainly has A1060 (O), mainly used in dry type transformer high and low voltage winding is used as a conductive material, aluminum with chemical components with GB/T 3190-1996 “wrought aluminum and Aluminum Alloy chemical composition” provisions, technical requirements and mechanical performance of the TUN900 0691998 version of the coil is made of aluminum foil products technical supply conditions. Transformer aluminum strip, mainly for large transformers, solar energy, power industry.
