Strip packaging polyester belt in tensile strength, ductility are sufficient to meet the needs in core binding, insulation, heat resistance, transformer oil can on all through strict testing, product performance has no other effect. The following is a thermogravimetric method for insulation material thermal stability test:

Decomposition temperature ( c ) A = C-3 / 7( B-C )

Heat resistant index ( c ) = Tg ( A+B ) / 2X

B: 50% break point temperature ( c )

C: 15% break point temperature ( c )

Results: B = 406.70 C, C = 375.58 C, A = 362.24 c,

Heat index: Tg = 179.66 degrees C ( X = 2.14); Tg = 170.12 degrees C ( X = 2.26); Tg ( X = 162.22 C
