Enamelled Wire
Enameled Wire
Enameled wire, also known as magnet wire or winding wire, made by coating a thin insulation layer of enamel or polyurethane over a copper or aluminium conductor.
Product Overview
Enameled wire, also known as magnet wire or winding wire, made by coating a thin insulation layer of enamel or polyurethane over a copper or aluminium conductor. The coating provides the electrical insulation that prevents short circuits between adjacent turns. Flat conductor thickness runs from 0.8 to 5.6 mm and width from 2.00 to 16.00 mm, at a width-to-thickness ratio of 1.4:1, with 130 polyester enameled wire among the categories supplied. Conductors can be solid or stranded.
Key benefits
Why Buyers Choose This Specification
Insulation That Fits Between Turns
A thin enamel coating insulates without taking winding space. That is the whole reason magnet wire exists instead of insulated cable.
Flat and Round Conductors
Flat wire packs more copper into the same coil window than round wire. Both are made, so the coil design decides.
Copper or Aluminium Core
Copper for conductivity, aluminium for weight and cost. Both are used depending on the design requirement.
Thermal Class Stated
130 polyester enameled wire is a defined thermal class. Insulation class is what determines the transformer's permitted operating temperature.
Application scenarios
Where It Is Used
- Transformer primary and secondary windings
- Electric motor and generator windings
- Inductor and choke manufacture
- Rewinding motors and transformers in repair
- Coil manufacture requiring flat conductor
- Solenoid and relay coil production
Who it is for
The Buyers This Product Suits
Transformer Manufacturers
Enameled wire is the winding material in every wound transformer, and the thermal class sets the design temperature.
Motor Manufacturers and Rewinders
Magnet wire in copper or aluminium is the basic input for motor winding and rewinding.
Coil Makers
Flat wire at a 1.4:1 width ratio is what packs a coil window efficiently.
Problems it solves
What It Fixes
Short Circuits Between Turns
The enamel or polyurethane insulation coating provides the electrical insulation and protection that prevents them.
Coil Windows That Will Not Take the Turns
Flat conductors fill a winding window more efficiently than round wire of the same section.
Insulation Failing at Operating Temperature
Selecting the correct thermal class, such as 130 polyester, is what matches the wire to the design temperature.

Sourcing And Inspection
This product is supplied through TrueGlow Imaging, working with manufacturing partners whose facilities are visited and verified rather than taken on trust. In-process quality control and delivery supervision are available so goods are inspected before the container is sealed. Certifications quoted on this page are those stated on the product specification and belong to that product range rather than to our trading entity, so ask for the certificate covering your specific item.
Handling guide
Getting It Right First Time
Step 1
Select the conductor material from the trade-off between conductivity and weight.
Step 2
Choose flat or round from the coil window and turn count.
Step 3
Match the thermal class of the enamel to the transformer or motor operating temperature.
Step 4
Confirm the width-to-thickness ratio, supplied at 1.4:1, against your winding machine.
Step 5
Contact the supplier if your specification falls outside the published dimensional scope.
Comparison
How It Compares In Our Range
Conductor material and shape, the two choices that matter.
| Copper Conductor | Higher conductivity, so fewer losses and a smaller coil for the same rating. |
|---|---|
| Aluminium Conductor | Lighter and lower cost, at the price of a larger conductor section for the same current. |
| Flat Conductor | 0.8 to 5.6 mm thick and 2.00 to 16.00 mm wide at 1.4:1 ratio. Fills the coil window efficiently. |
FAQ
Enameled Wire Questions
What is enameled wire?
