  • Time: 2022-07-22 18:09:57

130 single glass fiber enamelled rectangular copper wire is to wrap 1-2 layers of alkali-free glass fiber evenly on the copper conductor. It is impregnated and baked with insulating paint with the required temperature resistance index and compatibility, so that the glass fibers are The glass fiber and the conductor are bonded as a whole.

130 single glass fiber enamelled rectangular copper wire

The temperature resistance index of glass fiber enamelled rectangular copper wire has three grades of 130, 155, and 180, and the insulation thickness generally has four grades of 20, 30, 40, and 50. This product is widely used in the winding of transformers, electromagnets, electric welding machines or other similar electrical equipment products. The electrical bare copper wire produced by the extrusion process is an ideal material for the production of glass-coated copper wire.

Executive standard: GB/T7672-2008

Production range:

Copper aluminum round wire

Diameter size: φ1.7—φ6.0

If the selected specification exceeds the above range, please contact us


The copper flat wire should meet the requirements of GB5584.2-2009, and the resistivity at 20°C should not be greater than 0.017241Ωmm2/m

The glass wire should be tightly and evenly wound on the conductor, and the winding directions of the two layers of glass wire of the double glass-wrapped copper wire should be opposite.
