Fibreglass wrapped wire
According to customer’s requirements, copper or aluminum conductor is evenly wrapped with one or two layers of non-alkali fibreglass. Then it is impregnated in compatible insulating coating of required thermal class, baked to make a whole between fibreglass and conductor. There are three thermal classes of 130, 155, 180, four insulation thickness classes of 20, 30, 40, 50. The product is widely applied in transformers, electromagnets, welding machines or similar electrical instrument.

●Introduction: According to customer’s requirements, copper or aluminum conductor is evenly wrapped with one or two layers of non-alkali fibreglass. Then it is impregnated in compatible insulating coating of required thermal class, baked to make a whole between fibreglass and conductor. There are three thermal classes of 130, 155, 180, four insulation thickness classes of 20, 30, 40, 50. The product is widely applied in transformers, electromagnets, welding machines or similar electrical instrument.
●Standard：GB/T7672-2008

If the specifications is out of the above range, please contact us
●Raw materials：
The resistivity of aluminum flat wire can not be more than 0.028010Ωmm2 / m in 20 ℃.
The resistivity of copper flat wire can not be more than 0.01724Ωmm2 / m in 20 ℃.
●Conductor should be wrapped closely and evenly with fibreglass. The winding of two-layer fibreglass should be wrapped in counter direction. Meanwhile,Insulation thickness of double fibreglass wrapped copper or aluminum wire should be conform to the table as follow. Thickness of narrow side (B-b) is not considered
●Characteristic
Insulation of fibreglass wrapped wire has the advantage of wear resistance, adhesion, flexibility, good resistance to heat and good overload performance.
