Description

Technical Field

[0001] This utility model belongs to the technical field of silicone tubes for power engineering, and specifically relates to a silicone tube for power engineering. Background Technology

[0002] Silicone tubing serves as a carrier for the flow and encapsulation of liquids, gases, and other materials. In the industry, silicone rubber tubing can be categorized into "extruded tubing" and "shaped tubing," and is widely used in modern industry, defense industry, and daily necessities. Silicone tubing is produced by adding raw silicone rubber to a two-roll mill or a closed kneader, gradually adding silica and other additives, and repeatedly refining until homogeneous. Following industry product technical standards, the product is then extruded. Conductive silicone rubber can be used in the electronics industry. However, due to the different operating environments of silicone tubing in power engineering, long-term exposure to relatively humid environments can easily lead to corrosion and damage, significantly shortening its service life.
