State's reactor production reaches 1,000,000,000, accounts for annual production is worked as in the whole world 1/3.Enamel-covered wire amount about reaches 50,000 tons.Reactor line, electricity
The high-grade motor of 220V, 380V volt is pressed to use, 10KV-50KV high pressures, extra-high voltage grid are used.And many conventional reactors are usually
Only one layer of insulated paint, the instantaneous impulse wave caused by it can cause motor insulation generation problem, i.e., usually said corona is put
Electricity or shelf depreciation effect occur, and shelf depreciation is since the insulation for reducing winding wire, over time so as to can shorten
The life-span of motor.
Utility model content
The purpose of this utility model is, there is provided a kind of composite enameled copper round wire suitable for reactor.The utility model
