I need to make a 72VA 220-12V DC Transformer. The drawing gives me 158 lamination and I need to use 133. How do you convert a 158 lamination to 133 lamination?
There is no such thing as a 'd.c. transformer'. If this is a typo, and you really mean an 'a.c. transformer', then the number of laminations will act to reduce the eddy-current losses within the core, but should not affect the turns ratio of your transformer if that's what you are trying to achieve.
Why pet film used for lamination?
its good for lamination
What material used in side transformer s breather?
Silica gel crystals are used to dry any air drawn into the transformer.
Transformer Output power less than input power?
A: Absolutely a power transfer will have an internal loss of IR . for a power transformer the loss can be as much of 20% or more if other magnetics are involved like iron screw holding the lamination together. Usually brass is used to reduce that loss.
How do you reduce core losses?
There are various measures that can be taken to reduce core losses. Lamination of the transformer core is believed to reduce core losses significantly.
What is theMethod of lamination for flexible packaging?
Dear friend , The techniques used for lamination can be classified on the basis of adhesive system used. The most common lamination techniques are · Wet lamination - By using water based adhesives · Dry lamination - By using solvent based or solventless adhesives · Hot melt or wax lamination - By using wax or polymers like polyethylene, polyamides etc. · Extrusion lamination - By extruding polymers between two substrates In packaging industry, solvent-based & solvent free adhesives are commonly used for most of the flexible laminates .

What exactly is the lamination process used in laminated wood floors?
Lamination simply means layering. For instances a piece of plywood is layers of wood sheets with crossed grains pressed together. Layers of a material are stronger than a solid piece of the same material. Laminated flooring is made just like plywood, the layers are glued together and then bound together with a press.
What is the present excise duty of transformer oil?
to cool a winding of transformer and it is a insulating material and transformer oil is a purifing oil
Is there an available method for an experiment to show that the output of a transformer is dependent on lamination?
The output of a transformer is NOT dependent on laminations. It is dependent upon the turns ratio and input voltage and current. The core of transformers is often laminated to minimize eddy currents - currents that don't flow in the desired direction, and cause extra heating in the transformer (minimizing lowers the amount of losses in the transformer).
What is the best material of the core of a transformer?
The core is responsible for the hysteresis losses in a transformer. These are the losses associated with the ease, or otherwise, by which the core is able to become magnetised in one direction, demagnetise and, then, remagnetise in the opposite direction. These days, the type of material used (variations on silicon steel) are about as efficient as possible.
What is meant by low reluctance in transformer?
In a transformer, or on general, if a material is easily magnetized it has low reluctance.
What is the difference between a lamination and a delamination?
Laminations are the layers of material used to make flooring or other materials like the head of a tennis racket stronger by connecting or joining the thin layer with adhesives or glue. Delaminations are exhibited when the laminated material separates typically along the interfaces between material layers.
