Application: for analyzing the status of wire coating curing, find out the best technological parameters; the test result can also verify the relationship between the performance of enameled wire and its curing degree. The tester effectively guides the production, discern heat resistant grades and determine the thermal stability of enameled wire, and prevent the dielectric breakdown accidents.
1) Main technical parameter of the test instrument:
（1）TG100 is special for testing round wire (0.02-2.50mm); TG200 is special for testing flat wire; TG300 is used for testing both round and flat wire；
（2）Measuring range of D value: the ordinate zooms with no restriction, better suitable for testing polyurethane and self- adhesive wire which with higher D value；
（3）Maximum working temperature: 400℃. The temperature rise rate of the system is visible, and the accuracy of the same specification is comparable；
（4）Test time: 2 to 4 minutes according to the sample (class H ≤4min)；
（5）Test frequency: 1 KHz；
（6）Test precision: 0.01%；
（7）Tan delta value resolution: 0.00001；
（8）Automatic database filtering；
（9） Curves for five samples can be compared at the same time.
2) Basic configuration:
（1） Mainframe of tangent delta tester TG series;
（2） Acer commercial computer（22 inch screen）;
（3） A keyboard and a mouse for Acer computer;
（4） Canon colour printer;
（5）Graphite cream for test (1000g);
（6）One set of clamps for test;
（7）Technical operating specification;
（8）A dryer and a brush pen;
（9）Operation guide video and atlas analysis data (disc).
