1. The wires can be tested by 50HZ. A. C fire experiment. Or pressed within a minute after in water for six hows without pucture accroding to the following form.

2. Heat-resisting test: Be winded for ninety-six howrs at +200 0 C without breaking.

3. Cold-resising test: Be winded for two hours at +60 0 C without breaking.

4. Soaking in paint test: Be dryed for 12-14 hours at +135 0 C, then be soaled in faint for 30 minutes, then dryed and repeat accroding to the former procdrure, and finally winded after drying for 12-14 hours at +135 0 C, the insulating layer will never break or be sticky.
