Product Description

products details:

 

Enameled copper (aluminum) rectangular wire is a wire using oxygen-free copper rod or electrical round aluminum rod under extrusion by requested specification mould or dawning and annealing procedure, Then painted with required temperature tolerance level insulating coatings by mold type or blanket typ, after baking procedure, the conductor and insulating coating will become an integral product The product is now widely used in oil-immersed transformers,dry transformers,electric reactor ,motor ,choke coils and other similar electrical instruments.

Standard:GB7673-2008,GB/T7095-2008,GB/T6109-2008(IEC60371)and Enterprise Standards
 

Production Range:

Enamelled copper rectangular wire

b(Wide side size)   b:2.8mm-16mm

Enamelled aluminum rectangular wire
a(Narrow side size )a:2mm-5mm
b(Wide side size)   b:3.5mm-16mm

Resistivity

The electric resistivity of copper wire rectangular wire is no more than 0.017241
Ωm²/m,the electric resistivity of aluminum rectangular wire is no more than 0.02801 Ωm²/m with the temperature of 20ºC.

Size of conductor should conform to the following tables:   

Narrow side standard size a or wide nominal side size b(mm)	Deviation(mm)
a(b)≤3.15	±0.030
3.15<a(b)≤6.30	±0.050
6.30<a(b)≤12.50	±0.070
12.50<a(b) ≤16.00	±0.100

1.00<a≤1.60	0.5	±25%
1.60<a≤2.24	0.65
2.24<a≤3.55	0.80
a>3.55	1.00
Note:If the wide side b is more than 4.75mm, under the agreements between supplier and customer:  Fillet radius can be a/2 mm.  Fillet radius can be 0.8 mm.

Nominal external size

.Nominal external size should be the sum of standard conductor size and film thickness.

Minimum external size
.Minimum external size should be the sum of minimum conductor size and minimum film thickness.

Maximum external size.
Maximum external size should not exceed the sum of maximum size of conductor and maximum film thickness.

 Elongation

standard side of Narrow side of conduct a(mm)		Minimum elongation(%)
>	≤
- 2.5	2.50 5.60	30 32

Note:Non-proportional extension strength and elongation of semi-rigid copper should conform to the following table.

Type	Rp0.2(N/mm2) Non-proportional extension strength	Min  Elongation(%)	The max electric resistivity of copper in 20ºC(Ωm²/m)
C1	100<Rp0.2≤180	20	1/58.0
C2	100<Rp0.2≤180	20	1/57.5
	100<Rp0.2≤180	15	1/57.5
C3	100<Rp0.2≤180	15	1/57.0

Rebound resilience
The rebound angle of conductor should be no more than to 5°.

Note: semi-rigid copper is not in above standard.

Flexibility and Adhesiveness
Rod bending test
The insulation should not split after bending the narrow side and wide side of the wire under below rod diameter in the chart.

Bending of the rectangular wire		Rod diameter
Wide side size	≤10mm >10mm	4*Wide side size 5*Wide side size
Narrow side size	All size	4*Narrow side size

Adhesiveness
The distance of losing adhesiveness should be less than 1* wide side of the conduct when we draw 15% of the enameled rectangular copper wire.

Thermal shock
The insulation of the enameled rectangular wire should not crack when curling the wide side of the wire on the round rod with six times diameter size than the narrow side of the conductor. The minimum thermal shock temperature will be 20.c plus temperature-resist grade of conductor

Solvent resistance.
The layer of the coating shouldn't be scratched when using "H"rigid pencil to test the product handled by the standard solvent.

Breakdown voltage.
In the room temperature, At least four samples should not be breakdown in prescriptive voltage among total 5 samples; the failed sample should not be breakdown under 50% of prescriptive voltage.
We can test at high temperature if customer requires.b
