High Voltage Suspension Composite Tension Insulator With Clevis

A composite insulator is an insulating device composed of at least two different insulating components, primarily consisting of a core with assembled metal fittings and an outer sheath. Domestically, it is commonly referred to as a composite insulator or synthetic insulator, while internationally it is often called a non-ceramic insulator.

The core of a composite insulator is typically made of materials such as epoxy resin fiberglass pultruded rods, epoxy resin fiberglass wound tubes, ceramic, or resin. The core is an internal insulating component and a key structural member that withstands mechanical loads such as tension, bending, torsion, and compression. For hollow composite insulators, the core, in addition to its mechanical and insulating functions, also serves as a container for high-voltage electrical equipment.

The sheath of a composite insulator is generally made of materials such as silicone rubber, ethylene propylene diene monomer (EPDM), resin, or polytetrafluoroethylene (PTFE), with silicone rubber being the most widely used. As an external insulating structure, the sheath provides the necessary creepage distance and effectively protects the core from environmental factors and electrochemical corrosion.

Due to their different structural forms, porcelain insulators, glass insulators, and composite insulators differ significantly in the allocation of material functions. Porcelain and glass insulators are single-material structures, with both mechanical and electrical properties handled by the same material; while composite insulators, through the rational combination of multiple materials, achieve both mechanical load-bearing and electrical insulation functions, thereby fully utilizing the advantages of each material.

Transmission lines serve a wide range of functions, including linking radio transmitters and receivers to their antennas-where they are commonly referred to as feed lines or feeders-as well as distributing cable television signals. They are also used as trunk lines to route calls between telephone switching centers, support computer network connections, and carry high-speed data in computer systems.

In radio-frequency engineering, short sections of transmission line-often implemented as printed planar transmission lines-are arranged in specific configurations to form functional circuits such as filters. These structures, known as distributed-element circuits, provide an alternative approach to conventional circuit designs that rely on discrete components like capacitors and inductors.
