Study on the Property of HSYV-5e 4×2×0.5 Cable Preparation with Copper Single Crystal
Copper single crystal wire (diameter is 2.7 mm) was produced by self-made single crystal zone melting machine, cold-drawed into diameter of 0.51mm, produced into HSYV-5e 4×2×0.5 solid horizontal twisted cable according to YD /T 1019-2001. The electrical performance of copper single crystal wire and ordinary oxygen-free copper wire have been detected . The results indicated that the DC resistive of copper single crystal wire is decreased by 4.59 percent when comparing with that of ordinary oxygen-free copper, and an obviously improvement on signal damping can be observed; moreover deformation twins and grain boundary are the main characteristic of microstructure of copper single crystal wire after cold-drawing.
