According to the silicone rubber used in the cool shrinkable cable accessory, the proper-ties of stress relaxation under storage temperature of 40 ℃ and the operating temperatures of 70 ℃ and 90 ℃ were inversed through time-temperature equivalent principle, after the properties of relaxation were measured under high temperatures of 140 ℃ and 180 ℃. The test results can be used not only for the lifetime predictions of cable accessory in run but also for the instruction of accessory storage period in the factory under pre-expanded state.
