Class 200 grade aluminum winding wire refers to the winding wire which is drawn and extruded from 1070 electrical aluminum rod inside and coated with insulating paint for many times outside.
 
Conductor metal material: Aluminum
 
Conductor shape: round, flat
 
Production scope
 
Circle line: diameter: Φ 2.00mm -- Φ 6.00mm
 
Flat wire: conductor thickness dimension A: 0.40mm -- 5.60mm
 
Conductor width B: 2.00mm -- 16.00mm
 
Recommended width thickness ratio of conductor 1-20 (square wire can also be produced)
 
Material:  Soft aluminum wire shall not be more than 0.028000Ω•mm²/m at 20 ℃.
 
Insulation temperature class: 200
 
According to different requirements of electrical insulation, the thickness of paint film can be selected:
 
Round line: according to the national standard, it can be divided into 1-level paint film, 2-level paint film or 3-level paint film
 
Flat line: thin film 0.08mm-0.11mm, thick film 0.12mm-0.16mm. If the self-adhesive layer is applied externally, the thickness of the self-adhesive layer is generally 0.03-0.05mm, the deviation range of the total film thickness can be controlled within ± 0.015mm, and the extreme can be controlled within ± 0.010mm.
 



Characteristic of class 200 grade aluminum winding wire:
 
High adhesion, thermal stability, chemical resistance.
 
Purpose of  class 200 grade aluminum winding wire
 
Electric tool motor, micro motor and transformer, electronic components, instrument winding and other products. It is mainly used for winding of power transformer (oil immersed, dry-type transformer), traction transformer, motor (generator, motor) and various electrical appliances.
