Audited Supplier Double Glass-fiber covered wire
It includes double glass-fiber covered aluminum wire, of which double glass-fiber covered flat aluminum wire is the most popular shape among all transformer customers.
Product introduction: according to customer requirements, glass fiber covered wire is uniformly wrapped 1-2 layers of alkali-free glass fiber on a copper (aluminum) conductor, and it is impregnated and baked with insulating varnish of required temperature resistance index and compatibility. Make the glass fiber, the glass fiber and the conductor bonded into a whole. At present, the temperature resistance index of this type of product has three levels of 130, 155, and 180, and the insulation thickness generally has four levels of 20, 30, 40, and 50. The bare copper (aluminum) wire produced by the extrusion process is an ideal material for the production of glass fiber-coated copper (aluminum) wire
Executive standard: GB/T7672-2008
Production Scope:
Double glass fiber coated flat aluminum wire
Narrow side size a: 1.00mm-6.30mm
Wide side size b: 3.00mm-25.00mm
Double glass fiber covered rectangular copper wire
Narrow side size a: 0.80mm-5.60mm
Wide side size b: 2.00mm-16.00mm
Material:
The double-layer glass-fiber-coated flat aluminum wire shall meet the requirements of GB5584.3-2009, and the resistivity at 20°C shall not be greater than 0.0280Ωmm2/m
The double-layer glass-fiber-coated rectangular copper wire shall meet the requirements of GB5584.2-2009, and the resistivity at 20°C shall not be greater than 0.017241Ωmm2/m
Glass-fiber-coated wire should be wound tightly and evenly on the conductor. The winding directions of the two layers of glass-fiber-coated aluminum (copper) wire should be opposite, and the insulation thickness of the double-glass-fiber coated aluminum (copper) rectangular wire should meet the requirements of the following table , The insulation thickness (Bb) on the narrow side is not specified.
The breakdown voltage of the glass-fiber covered wire should meet the requirements of the following table
