What are the characteristics of glass insulators
Abstract：After vacuum injection and continuous pultrusion of epoxy glass drawing rods, the glass fibers are impregnated with epoxy resin. It is solidified and used in overhead lines. Commonly used insulators include needle insulators, butterfly insulators, suspended porcelain bottle insulators, porcelain cross arm insulators, rod insulators and tensioning insulators, etc.
After vacuum injection and continuous pultrusion of epoxy glass drawing rods, the glass fibers are impregnated with epoxy resin. It is solidified and used in overhead lines. Commonly used insulators include needle insulators, butterfly insulators, suspended porcelain bottle insulators, porcelain cross arm insulators, rod insulators and tensioning insulators, etc.
The core rod of the insulator is formed by extrusion and drawing of epoxy resin glass fiber. The outer surface of the glass fiber is bonded with epoxy resin, and it is the glass fiber that bears the load. Rainwater and moisture can easily form acidic liquids under a high-voltage electric field. If the end seal of the FS355 composite insulator is poor or the outer sheath is damaged. The acid solution will seep into the interior of the core rod along the interface between the sheath and the core rod. This leads to the swelling of the epoxy resin. Until it cracks and disintegrates, along with the destruction of the epoxy resin matrix. The bonding surface between epoxy resin and glass fiber is etched by acid and water media. Causes the bonding surface to peel off, allowing acid and water media to directly touch the surface of the glass fiber? Contact with basic oxides such as CO and MgO in glass fibers. These basic oxides react with acid solutions to form high-stress zones in the lattice of glass fibers, leading to microcracks and a decline in the mechanical properties of the glass fibers until they break. With.
Silicone rubber and core rods are a kind of composite material, so this insulator is called a composite insulator. However, from the perspective of the structure of this insulator, it is composed of two materials and is a composite structure. Therefore, a composite insulator can also be regarded as a reference to its structure.
The above is the information of the composite suspension insulator. If you have any questions about the parameters, please contact us to obtain the latest information.
Ordinary insulators are usually made of glass or ceramic. The mechanical strength of the surface layer of glass insulators is high, while the transparency of glass makes it easy to detect fine cracks, various internal defects and damages during shape inspection. Insulators made of ceramics have excellent electrical and mechanical properties and are also flexible in assembly. However, defects are not easy to be detected. For the zero-value detection of ceramic insulators, it is necessary to climb the tower for individual piece inspection, which requires a lot of manpower and material resources. At the same time, the probability of accidents caused by lightning strikes and contamination flashover is high.
