Dual Coated (PEI+PAI) Wire 200 Class

Product Overview

Copper Dual Coated PEI PAI Wire 200 degree Class is a magnet wire, the thin wire that is wound into coils inside motors and transformers. When current flows through the coil, it creates the magnetic field that turns a motor or changes the voltage in a transformer.

The wire has a copper conductor with a dual layer of PEI and PAI enamel. The enamel keeps the turns of the coil apart, so current flows along the wire and not between the turns. Because there are two layers, the insulation is stronger and lasts longer than a single coat in hard working conditions. This is why PEI PAI copper winding wire is a trusted choice for high temperature magnet wire jobs.

Product Specifications

Key Features

• 200 degree class heat rating: dependable insulation in hot and demanding machines.

• Strong chemical resistance: the coating stands up to the chemicals found in many industrial settings.

• Abrasion resistance: the tough surface survives fast winding, where the wire is pulled and bent many times.

• Overload resistance: the insulation copes with sudden extra load better than ordinary wire.

• High dielectric strength: better electrical insulation and a longer life for the coil.

• Flexible under thermal cycling: the wire stays flexible through repeated heating and cooling.

Benefits of Using 200 Degree Copper Dual Coated Wire

Fewer coil failures. The second enamel layer gives extra protection exactly where a weak spot would cause a short circuit between turns.

Safer margin for hot machines. A 200 class rating gives you room when your machine runs close to the limit of a lower grade.

Smooth, reliable winding. The tough coating and flexible copper conductor let the wire run cleanly on fast winding machines.

Longer working life. Strong dielectric strength and resistance to heat, chemicals and abrasion help the coil last through long, continuous use.

Efficient, compact coils. Copper carries current very well, so the coil can stay compact and run efficiently.

How the Dual Coating Works

The two enamel layers work together. They sit tightly on the copper, and they flex with it when the wire is bent, pulled or wound into a tight coil. If the outer layer is scuffed or stressed during winding, the layer beneath still keeps the turns of the coil apart. This is what gives the wire its strength under overload, and it is why a dual coated wire is chosen for coils that cannot be easily repaired or replaced.

The coating also has to survive heat. As a machine warms up and cools down, the copper and the enamel expand and shrink. A well-made dual coat stays bonded and flexible through these cycles instead of cracking, which keeps the insulation intact for the life of the coil.

Applications

Our PEI PAI enameled copper wire is used where strength and reliability matter as much as heat resistance:

• Electric motors: especially motors that run hot or under heavy, continuous load

• Transformers: where the coil must stay safe through long working hours

• Automotive components: where heat, vibration and tough conditions are part of daily use

• Industrial equipment coils: where chemicals, vibration or overload are a risk

Why Choose a Dual Coated Winding Wire?

A single enamel layer is often enough for moderate heat. For example, our Modi Polyester Wire 180 Class suits many transformers and motors at a lower cost.

Choose dual coated winding wire when the working conditions are harsher. If the coil gets very hot, meets chemicals, faces sudden overload or is wound at high speed, the second layer adds protection. It also helps when a machine is switched on and off often, since the wire goes through many cycles of heating and cooling. For any coil that needs a class 200 magnet wire, this is the grade to pick.

Quality and Testing

Every spool of Copper Dual Coated PEI PAI Wire goes through checks before it leaves our plant. Our in-house laboratory tests the wire for electrical integrity, mechanical strength and long-term reliability. Our enameled wires are made to IS 13730, IEC 60317 and NEMA MW1000, and our ISO-certified processes keep each batch consistent.

Winding Tips for Best Results

How you wind the wire matters as much as the wire itself. These simple steps help you get the best from 200 degree copper dual coated wire:

• Set the winding tension to suit the wire size, and keep it even from start to finish.

• Check that guides, pulleys and nozzles are smooth and free of burrs or sharp edges.

• Avoid sharp bends at the ends of the coil, where the enamel is under the most stress.

• Run a trial coil when you switch to a new wire size or a new winding machine.

• Inspect finished coils for scratches or exposed copper before they go into the machine.

Handling and Storage Tips

Good wire can still be damaged by poor handling. These habits protect the enamel:

• Keep spools in a dry, clean place away from moisture and heat.

• Store them away from oil and strong chemicals.

• Avoid dragging the wire over rough or sharp surfaces.

• Do not bend the wire sharply or pull it too hard while winding.

• Use even tension so the enamel does not crack.
