FZ-7401 低溫冷繞試驗機
CORD WINDING CRACK TESTER
UL1581，VDE，JIS-C3005
導體斷面積 100mm2 以下之試料在本機內冷卻 1 小時后，立即以均勻之速度將試樣繞卷于規定直徑之圓桿上，斷面積 100mm2 以上之試料則先行繞卷，再冷卻相同之時間后，立即以反方向繞卷于圓桿上。試驗后取出試樣，檢視試樣表面是否產生龜裂、裂痕。 
If the cross-sectional area of conductor is less than 100mm2，then specimen must be put into testing chamber for freezing for one hour，after that immediay rolls specimen around the specified rod in a uniform speed 。Otherwise，for the cross-sectional area over 100mm2，roll the specimen before hand and put into chamber for freezing one hour。Afterwards，immediay roll specimen around the rod in reverse direction。Finally，take out of specimen for checking whether its surface has crack or fissure or not。
