Z955 is a type of insulation paper which is calendered at high temperature. It is made of pure aramid fiber by wet paper-making and calendering at high temperature. It has excellent high temperature resistance, excellent electrical insulation, mechanical properties and flame retardancy, good flexibility and tear resistance, excellent chemical stability and compatibility. It has good compatibility with different types of insulating paints and good oil resistance. It can be used for a long time at 200 °C with H and C insulation systems.
Application Fields
Z955 is suitable for all known occasions that require sheet-type electrical insulation materials. It can operate under short-term overload and has strong overload resistance. It can be used for inter-turn, layer and inter-end insulation of various transformers (traction transformers, mine explosion-proof transformers, power transformers, reactors, rectifiers, etc.), as well as slot, inter-turn and gasket insulation of various motors (traction motors, hydro power motors, wind power motors, mining motors, metallurgy motors, ship motors and other motors) and power generators. In addition, it is also widely used in the fields of batteries, circuit boards, switches and other electronic appliances.

Note:
MD: Machine direction of paper ，CD: Cross machine direction of paper
1. AC Rapid Rise mode with φ6mm cylindrical electrode.
2. The test frequency is 50 Hz.
Note: The data in the data sheet are typical or average values and cannot be used as technical specifications. Unless otherwise stated, all data were measured under “Standard Conditions” (with the temperature of 23℃ and the relative humidity of 50%). The mechanical properties of aramid paper are different in machine direction (MD) and cross machine direction (CD). In some applications, the direction of the paper can be adjusted according to the needs to exert its best performance.
