Class F insulated hollow copper flat wire is the stator wire for 300,000/600,000 KW generator sets imported from the United States Large, the heat generated is also large, part of the winding must be insulated hollow copper wire, so as to facilitate water cooling in the wire.
The hollow magnet wire is made of high-conductivity oxygen-free copper, which is produced by special high-pressure pultrusion equipment. The average grain diameter of the copper metallographic structure is 0.025-0.065mm. The tensile strength of the hollow copper flat wire is above 260N/cmm³, and the elongation The rate is greater than 30%, the resistivity is less than 0.017241Ωmm²/m, the hollow can withstand 20 minutes without leakage under the water pressure of 3.5Mpa, and the eddy current flaw detection is less than 0.17mm through the 200ml/min water flow test. crack.
The insulation of the copper flat wire is a mixed cladding of polyester fiber and electrical glass fiber, which is baked with F-grade adhesive resin. , This product is produced with innovative technology and has good mechanical properties and heat and humidity resistance. Scope of application: Mainly used in 300MW, 600MW, 1000MW and other large and medium-sized steam turbine generator stator coils Mainly used in large and medium-sized steam turbine generator sets, nuclear power generation coils, the success of this hollow magnet wire winding technology is very important for large power generation equipment. important.
