Which coil is thicker in transformer?
In a step-up transformer, the primary coil is made of thicker wire. This is because in a step-up transformer the number of turns in the secondary coil is more than the number of turns in the primary coil.
What material is used for the coil of a transformer?
Copper
Copper is the material of choice for power transformer conductors due to its superior short-circuit withstand capabilities. It is a basic principle of electromagnetic induction that an electric current flows in a closed coil placed within a varying magnetic field.
Why thick wires are used in transformer?
If the output voltage is smaller than the input voltage, then output current can be larger than the input current.. such a transformer is called a step down . The larger current needs thicker wire ,in order to reduce energy loss due to resistance.
Why is thick copper wire used in windings?
This loss can be reduced by using low resistance wire for the coils. Thick copper wire is used for this winding, because wire of a bigger cross sectional area has a lower resistance and wire of a material of low resistivity has a low resistance.

What is a coil winding machine?
Electrical coil winding machines are used to wind coils for motors, transformers, inductors, and chokes. Coil winding equipment is used in a variety of wire winding, wire welding, and wire bonding applications.
How do you make a transformer winding?
Designing a transformer using an example:
- Sec.Volt-Amps(SVA) = Vs * Is = 60 * 4.44 =266.4VA.
- Prim.Volt-Amps(PVA) = SVA / 0.9 = 296.00VA.
- Prim.Voltage (Vp) = V2 / (n2/n1) = 60/0.5= 120V.
- Prim.current (Ip) = PVA/Vp = 296.0/ 120 = 2.467A.
- Core Area(CA) = 1.15 * sqrt(PVA) = 1.15 * sqrt(296) = 19.785 cm²
Why the thick copper wire is used in winding?
Thick copper wire is used for this winding, because wire of a bigger cross sectional area has a lower resistance and wire of a material of low resistivity has a low resistance.
What’s the primary difference between the wire in the primary winding and the wire in the secondary?
The primary winding is the coil that draws power from the source. The secondary winding is the coil that delivers the energy at the transformed or changed voltage to the load. Usually, these two coils are subdivided into several coils in order to reduce the creation of flux.
