Description

Overview

300g spool of polyurethane enameled copper wire, QA-1/155 grade, in diameters from 0.04mm to 1.5mm and in two insulation colours — natural copper or red. The colour makes it easy to distinguish windings from each other in multi-coil assemblies.

Specifications

  • Grade: QA-1/155 (polyurethane enamel, direct solderable)
  • Net weight: 300g per spool
  • Available diameters: 0.04 / 0.05 / 0.06 / 0.07 / 0.08 / 0.09 / 0.1 / 0.13 / 0.15 / 0.2 / 0.25 / 0.3 / 0.4 / 0.5 / 0.65 / 0.8 / 1.0 / 1.3 / 1.4 / 1.5 mm
  • Insulation colours: copper (natural) or red
  • Maximum continuous temperature: 155°C

Purpose

A smaller spool for people who need several sizes rather than a kilogram of one. The red insulation is the practical feature: when a transformer has a primary and a secondary wound from the same gauge, colour-coding the windings removes a whole class of wiring mistakes.

Applications

  • Transformer and inductor winding
  • Motor and relay coils
  • Multi-winding assemblies needing colour distinction
  • Jumper wires and small electromagnets

How to Use

  1. Select diameter and colour per winding; use red for one winding and natural copper for the other.
  2. Wind with the spool upright and the wire paying off freely.
  3. Terminate by soldering at 360–400°C — the polyurethane enamel burns back at soldering temperature.
  4. Keep the coil below 155°C continuous.
