Basic Structural Description Of Insulators

In the design and operation of power installations, the structural design of dead end insulators is fundamental. dead end suspension insulators typically consists of two main parts: a ceramic body (or insulating substrate) and metal fittings (or hardware). This structural arrangement stems from the dual requirements of high-voltage systems for both electrical and mechanical performance.

The ceramic body bears the primary responsibility for insulation. It is made of insulating materials such as porcelain clay, sintered to form an insulating medium with high resistance and high mechanical strength. This part determines whether the polymer deadend insulator can withstand electric fields, cope with environmental factors such as humidity, pollution and climate, and support the weight of the conductor.

Metal fittings are used to secure the porcelain dead end insulators to towers or electrical equipment connection structures. These typically include steel caps, flanges, or connectors, used for the mechanical connection between the conductors and the supporting structure. This part must ensure mechanical stability and secure installation.
