Description
Overview
Polyesterimide enameled round copper wire, QZY-2/180 grade, heat class 180°C (Class H). Supplied on a 500g spool in diameters from 0.13mm to 1.5mm. The double-layer polyesterimide film provides high dielectric strength and resistance to abrasion and solvents, making it suitable for coils that run hotter than standard 155°C wire allows.

Purpose
Winding wire is the raw material for electromagnets and coils: the enamel insulates adjacent turns so current flows along the wire instead of shorting turn-to-turn. The 180°C Class H rating is what distinguishes this from ordinary 155°C wire — it keeps its insulation in motors and transformers that run hot.
Applications
- Motors and generators with elevated operating temperatures
- Power transformers and switch-mode transformers
- Inductors, chokes and relay coils
- Instrument coils and electromagnets
How to Use
- Choose the diameter from your turns count and current requirement — a thinner gauge gives more length per 500g.
- Keep the spool upright so the wire pays off naturally while winding, avoiding kinks.
- Wind with even tension and keep the turns side by side.
- Strip the enamel at the termination by scraping or by soldering at high enough temperature to burn it back.
- Keep continuous operating temperature below 180°C.
Note: the stated diameter refers to the bare copper conductor excluding the enamel. A calliper reads the outer diameter including varnish, so it will measure slightly larger than nominal.
