Simulation test method for influence of silicone grease on contraction of cold-shrinkable cable accessory

The invention belongs to the technical field of silicone grease testing, and particularly relates to a simulation test method for influence of silicone grease on contraction of a cold-shrinkable cable accessory. The swelling rate of the silicone grease is tested by adopting a thermal aging experiment method, and comparing is carried out to acquire the shrinkage rate equal to (the diameter after shrinkage of the silicone grease region-the diameter after shrinkage of the silicone grease-free region)/the diameter after shrinkage of the silicone grease-free region * 100%. According to the simulation test method for influence of silicone grease on contraction of the cold-shrinkable cable accessory, the most common silicone rubber cold-shrinkable product cold-shrinkable tube is selected as a test sample, a silicone rubber test piece does not need to be manufactured, the material selection of the test piece is simple and common, the influence of temperature, vulcanization, environment and the like during manufacturi
