The Composite Line Post Insulator is a high-performance insulator to supports and insulates conductors of transmission and distribution lines. The insulator is made with a fiber-reinforced polymer core that is wrapped in a durable silicone rubber shell that resists environmental stresses including UV radiation, pollution, and extreme weather. The composite structure of the aircraft provides excellent mechanical strength and electrical insulation for reliable operation under demanding outdoor conditions. It differs from other insulators mounted vertically or horizontally to produce clearance between conductors, to prevent arc, and to carry the weight of conductors under different load conditions. With this design, the silicone rubber shell combats the tendency of contaminants to accumulate and retains its hydrophobic properties against salt, dust, or industrial dust to prevent flashovers in locations prone to such pollution.
Special design allows the composite line post insulator to withstand high bending and cantilever loads, supporting the conductor and resisting the effects of wind, ice, and other environmental stresses without deforming. Its ability to use inclined or dead-end locations in a transmission line makes it particularly suitable.
It shows these line post insulators have different installation methods and can be installed in vertical, horizontal, and overhanging orientations as per the design and operating requirements of the transmission line. It is this flexibility that enables the mesh to be used with different structural settings that ensure reliable insulation and support for any of the grid arrangements.
It has continuous hydrophobicity in its silicone rubber shell and no water film is formed on the insulator surface, even in severe isolation pollution or humid conditions. Reduction of leakage current and reduction of the risk of flashover — this feature is very important, especially in polluted areas.
Its design minimizes corona discharge — it can lead to energy loss and perhaps damage in high-voltage applications. Its smooth silicone surface and specially designed structure control and minimize the corona effect, promoting efficient and reproducible transmission of energy.
Because it is significantly lighter than porcelain or glass insulators, the mechanical load on the pole is reduced, and thus handling and installation are easier. Despite their lightweight construction, this material still has very high durability and resilience for longevity of use in harsher outside environments.
In comparison with traditional insulators, the polymer-based material used in this line post-type insulator is more durable. This impact and vandalism resistance reduces maintenance costs and extends service life, in particular in areas where insulators can be physically damaged.
Its principal function is to offer constructive and rigid support to conductors on transmission and distribution lines so that the insulation of these conductors is assured under specified stresses due to the ambient and operating conditions, and so that the conductors are rock steady under specified stresses due to the ambient or operating conditions. The combination of a fiber-reinforced core and a silicone rubber shell was used to create this composite structure so that the mechanical loads due to wind, ice, and line tension as well as the electrical stresses that may result in flashover or arcing are tolerated. Transmission line post insulators besides their mechanical support are also critical barriers to prevent leakage. The hydrophobic surface properties of its surface resist contaminant accumulation and reduce the likelihood of surface currents, making maintenance requirements less restrictive than in polluted environments. To ensure the integrity and efficiency of long-distance power transmission, the insulating performance of this insulator is needed to be reliable.
