Copper Modi Polyester Wire 130 Class

What Is Copper Modi Polyester Wire 130 Class?

Copper Modi Polyester Wire is a high-grade enameled copper wire. A thin layer of polyester-based enamel covers the copper conductor. This enamel is the insulation. It lets the turns of a coil sit tightly side by side without touching, so current flows only along the wire and not between the turns.

The word "modified" points to the improved polyester enamel. It gives the wire reliable insulation and good mechanical strength. The wire resists moisture, rubbing and most solvents, which helps it stay in good shape during winding and in daily use.

The wire has a smooth surface and a steady diameter along its whole length. Both matter to the person running the winding machine. A smooth wire slides through the guides easily, and an even diameter lets the coil lay down in neat, tight layers. Neat layers mean stable electrical performance from one coil to the next.

Key Features

These are the main features of our copper modified polyester wire in 130 class:

• Rated for 130 class: it works reliably at temperatures up to 130 class.

• Strong insulation: the polyester enamel protects against short circuits between turns.

• Smooth surface: the wire winds quickly and easily.

• Even diameter: coils stay neat and electrical performance stays steady.

• Good resistance: it stands up to moisture, rubbing and most solvents.

• Cost-effective: it gives dependable service without the cost of a higher heat grade.

How the 130 Class Rating Works

Every enameled wire carries a thermal class. The class tells you the heat level the enamel is built to handle during normal work. A higher number means the wire can run in hotter conditions. This wire is rated 130 class, which makes it a good fit for moderate-temperature environments.

It helps to look at the real temperature inside your machine, not only the room temperature. A motor warms up as it runs, and the coil sits at the hot centre of it. If your coil stays within the 130 class limit under normal load, this wire is a sensible and economical choice. If the coil runs hotter, a higher class will last longer.

Many makers use 130 class for general-purpose products because it covers a very wide range of everyday jobs. It avoids paying for heat resistance that the product never needs.

Where Copper Modi Polyester Wire 130 Class Is Used

This copper polyester wire is common in electrical winding work where heat is moderate. Typical uses include:

• Electric motors for fans, pumps and small machines

• Distribution and small transformers

• Relays and contactors

• Coils, chokes and solenoids

• Household appliances

• Other electromagnetic devices

In all of these, the wire does the same job. It carries current through many tight turns and keeps each turn insulated from the next. Because the wire is smooth and even, it also suits automatic winding machines that run at good speed.

Benefits of Using Copper Modified Polyester Winding Wire

Dependable insulation. The polyester enamel keeps turns apart, which lowers the chance of short circuits inside the coil.

Easy and fast winding. The smooth finish reduces friction on the machine. Your operators spend less time fixing breaks and untidy layers.

Steady performance. A consistent diameter means each coil you build behaves like the last. This helps when you make products in large numbers.

Good protection. The enamel resists moisture, rubbing and most solvents, so it keeps its insulating quality through varnishing and use.

Good value. For products that run at moderate temperatures, 130 class gives the performance you need at a sensible cost.

Copper conductivity. Copper carries current well, so coils can stay compact. If you want to compare it with lighter, lower-cost options, see our super enameled aluminum winding wires.

Is 130 Class Right for You? How to Choose

A few simple checks will help you choose well:

1. Check the working temperature. Measure or estimate the real temperature of the coil under full load. If it stays within 130 class, this wire is a good match.

2. Think about the product. A household fan motor and a heavy industrial transformer do not need the same wire.

3. Match the wire size to the load. The conductor must be thick enough for the current your coil carries.

4. Consider your winding machine. Smooth, even wire suits fast winding.

5. Plan for the future. If your design may get hotter later, talk to us about a higher class.

If your coil needs to be soldered directly without stripping the enamel first, you may prefer a different grade. Our copper polyurethane self solderable wire 155 class is made for exactly that job, and you can see every grade on our super enameled copper winding wires page.

Winding and Handling Tips

Even good wire can be damaged by poor handling. These habits protect the enamel and help you get the best results:

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

• Keep them away from oil and strong chemicals.

• Do not drag the wire over rough or sharp edges.

• Avoid sharp bends and sudden pulls while winding.

• Keep the winding tension even so the enamel does not crack.

• Handle spools by the flange, not by the wire.

• Close or cover opened spools when they are not in use.

Small habits like these cost nothing, and they prevent most insulation faults before the coil is even finished.
