Coated sleevings are used to satisfy electrical, as well as, thermal, physical and chemical requirements. Generally, braided electrical insulating sleevings which have been continuously coated are characteristically identified with a temperature classification (thermal level at which sleeving can operate continuously) and a grade (defined through dielectric strength breakdown or puncture voltage) as follows:
DIelectric Strength Breakdown Voltage (Volts)
No Dilectric Guarantee
Notes：(1) Conditioned for 96 hours at 23°C and 50% relative humidity (C-96/23/50) before testing.
