The current test method for silicone grease is to make a test piece of silicone rubber with cold shrinkable accessories and soak it in silicone grease for testing. There are certain differences in the products of shrinkage accessories, and the amount of silicone grease immersed in the test piece is also different from the amount applied in the actual construction process. The reference value of silicone grease application in accessories is not high

Abstract
The invention belongs to the technical field of silicone grease testing, and in particular relates to a retraction simulation test method for silicone grease affecting cold-shrinkable cable accessories. The thermal aging test method is used to test the swelling rate of the silicone grease, and the comparison shrinkage rate = (diameter after shrinkage of the silicone grease area - diameter after shrinkage of the non-silicon grease area) / diameter of the non-silicon grease area after retraction * 100%. Silicone grease affects the retraction simulation test method of cold-shrinkable cable accessories described in the present invention, selects the most commonly used silicone rubber cold-shrinkable product cold-shrinkable tube as the test sample, does not need to make silicone rubber test pieces, and the sample material selection is simple and common, and overcomes the It solves the problem that there are differences between the silicone rubber test piece and the cold-shrinkable cable accessory product itself due to the influence of temperature, vulcanization, and environment during the production of the silicone rubber test piece, and improves the accuracy, authenticity and applicability of the test results.
Description
technical field [0001] The invention belongs to the technical field of silicone grease testing, and in particular relates to a retraction simulation test method for silicone grease affecting cold-shrinkable cable accessories. Background technique [0002] Silicone grease is a substance that is coated on the composite insulation interface of cold-shrinkable cable accessories and cable main insulation during installation to lubricate, seal and improve the breakdown strength of the composite interface. Therefore, silicone grease is a necessary accessory material in the installation process of cold shrinkable cable accessories. [0003] The swelling rate of silicone grease is one of the important parameters of silicone grease performance. In principle, under the premise of meeting the product and cost requirements, the lower the swelling rate of silicone grease absorption, the better. At present, there are many kinds of silicone grease on the market, which makes the selection o...
