Enameled Wires

Enameled Wires


Enameled wire is a thin wire insulated with the help of coating. The core material used in it is copper and it is covered with a thin layer of enamel. It is primarily used in electric motor coils. It produces magnetic flux when electricity passes through it. Though enameled wire is insulated but there is no need of stripping off the insulation as for other insulated wires. These wires can be soldered as well.

Uses of Enameled wires

* Enameled wire is used in motor coils.
* Enameled wire is used in the construction of electromagnets.
* Enameled wire is also used in construction of transformers and inductors.

Properties of Enameled Wires

* Enameled wires have excellent resistance to heat. That's why they are used in making electric coils. They are also resistant to heat shock.
* They are also resistant to wearing and tearing.
* They offer especially magnificent resistance to refrigerant materials.
* They are smooth, hard, and durable.
* They are chemically resistant, and cannot burn.

Application of Enameled Wires

* Enameled wires are appropriate to be used in compressor motors of freezer, refrigerator and air conditioner.
* They are also best suited to be used in the motors which operate at high temperature, high speed. They are also suitable for those motors which require repeated starting.
* They are applied in hermetical motors and coils of electrical devices.
* They are suitable for those applications where high speed automatic winding is needed.


Types of Enameled Wires
On the basis of materials used in making the core of the wire the enameled wire can be divided into two types. Mainly aluminum and copper is used as the major material for these wires. Sometimes copper-clad aluminum wire is also used.

* Enameled Aluminum Wires: In this category of enameled wires the core material used in the conductor is aluminum. They have very good electric conductivity and are low weight. These wires have high hot impact performance. The enameled aluminum wires are ideal for electric machinery with short and periodic workloads.

* Enameled Copper Wires: The material used in making conductor in this type of wire is copper. These enameled wires have high thermal resistance and are thermally stable. They are resistance to freon. They are resistant to high overload and can bear high heat shock. They are used for smoke and heat exhaust motors and inverter-driven motors.

Classification of Enameled Wires
Enameled wires are classified on three basis. They are classified by

* Diameter
* Temperature
* Isolation
