An enamelled copper strip is basically a copper wire which has been coated with a thin insulation layer. It is also popularly referred to as a magnet wire which may be made from either copper or aluminum. This enamelled copper strip finds extensive use in building transformers, motors, inductors, hard disk actuators, speakers, electromagnets and various other applications which need tight insulated wire coils. This product is therefore widely used for making pumps and stabilizers, auto electrical equipments and fans which need to have high mechanical properties. Even rotating or static equipments like generators and pump motors, voltage stabilizers and heavy domestic machines such as washing machines and mixer-grinders require this enamelled copper strip.
How does the enamelled copper strip work?
Although this copper wire has been described as enamelled, this does not imply that the wire has been coated with enamel paint layers or vitreous enamel which is prepared using fused glass powder. This enamelled copper strip basically uses between one and four layers of the polymer film insulation to offer a sturdy and continuous insulating layer. The main idea behind coating the wires with insulation layers is to prevent outbreak of fire due to short circuits when the wires have been wound to form coils. This is the reason why this type of wire is widely used for making motor and electromagnets, inductors and transformers. To make it easy to manufacture inductive equipments like inductors and transformers, the wires are soldered. They are prepared using 99.99% ETP grade copper backed by high-end enamel.
Why is the enamelled copper strip popular?
This special wire is popular amongst manufacturers of electrical equipments because it offers great thermal stability, electrical properties, mechanical properties, solvent resistance. This is why it is used for electric welders, electrical machines, cutting machines and dry-type transformers. It has great flexibility and balanced thermal properties. It can function at a constant high temperature and offers great chemical stability. The enamelled strip also has good dry and wet di-electric properties with a high resistance to overloading. The surface is also smooth which is conducive to high speed winding.
Where can you buy enamelled copper strip?
When you are planning to purchase the enamelled copper wires from manufacturers, you should make it a point to ask for referrals. It is always a good idea to do a background check on the track record of the company you have chosen. You can shortlist names of the most reputed manufacturers of such strips online and then verify their credentials before buying from anyone. It may also be wise to search for reviews of these products posted by buyers on different review websites. These reviews are very helpful for making a decision because they highlight the pros and cons of using enamelled copper wires. You should also compare prices of the product from different suppliers and then choose the company which offers you quality products for affordable prices. The company should also have a customer-friendly return and exchange policy in case you have to return a product.
