Product Description

products details:
Nomex Paper Wrapped Copper (aluminum) Rectangular Wire
 
Kraft paper(the thermal class 105ºC), Nomex paper,HPI-Green paper(the thermal class 120ºC) wrapped copper (aluminum) rectangular wire is extruded or drawn from oli-free copper rod or electrical round aluminum rod with requested specification mould. Then the copper or aluminum conductor is wrapped with one or more layers insulated paper. The product is widely used in oil-immersed transformers,electric reactor ,motor ,choke coils and other similar electrical instruments.


Standard:GB7673-2008(IEC60371)and Enterprise Standards

Production Range:
(Paper wrapped copper rectangular wire)
a(Narrow side size )a:1.18mm-5.6mm
b(Wide side size)   b:2.8mm-18mm
(Paper wrapped aluminum rectangular wire)
a(Narrow side size )a:1.25mm-8mm
b(Wide side size)   b:3mm-18mm

Resistivity:
20ºC,0.017241 Ωm²/m,0.02801 Ωm²/m.
In temperature of 20ºC,the resistivity of copper retangular wire is no more than 0.017241 Ωm²/m,the resistivity of aluminum retangular wire is no more than 0.02801 Ωm²/m.

Size of conductor should conform to the table as follows:   

Insulation thickness
Nominal Insulation thickness 0.30 0.40 0.45 0.60 0.95 1.05 1.35 1.60 1.95 2.45 2.65 2.95 3.95
Max Insulation thickness 0.33 0.44 0.50 0.65 1.02 1.13 1.45 1.70 2.05 2.57 2.78 3.10 4.15
Min Insulation thickness 0.27 0.36 0.40 0.56 0.88 0.98 1.29 1.52 1.86 2.33 2.52 2.81 3.85

Conductor fillet radius r

Maximum external size
Maximum external size no more than maximum size of conductor add double maximum insulation thickness.

Note: The structure of paper wrraped copper (aluminum) rectangular wire should conform between the supply and demand requirements. For example , the layers of insulation paper ,method of wrapping,insulation thickness and so on.
The surface of conductor should without copper powder and the other impurities ,every layer of the insulation paper should be continuous,firm,and without wrinkle ,without joint point and binding material except tail end of insulation paper .

Note:Proof strength at non-proportional extension and elongation of semihard copper should comform to the following table.

Type Rp0.2(N/mm2)
Proof strength at non-proportional extension
Min  Elongation% the resistivity of copper in 20ºC(Ωm²/m)
C1 100<Rp0.2180 20 1/58.0

100<Rp0.2180 15 1/57.5
C3 100<Rp0.2180 15 1/57.0

Rebound resilience
The rebound angle of conductor should less than or equal to 5°.

Note: Except semihard copper.

 Flexibility and Adhesiveness

Because of the difference between the insulation thickness and layers of the paper ,  flexibility and adhesiveness should conform to mutual consultation between supply and requirements.
