Arrested Development: Trends in the Market for Arrester Equipment

Arrester Equipment trends

Arresters perform an important function within the utility grid, namely they prevent the over electrification or power surge in a component of the network, whether high-voltage, medium-voltage, or low-voltage component. Different types of surge arresters serve different voltage levels and use cases. In this blog post we cover 2 current trends in the market.

  1. Metal Oxide Varistor (MOV): While it might seem funny to call MOV a trend, since they’ve been around for over 40 years, it can be considered an overarching market trend that these are ever increasingly used for managing the surge of transient power.
  2. Silicon Rubber Housing: The housing in an arrester is an important component. More traditional housing using organic carbon-based polymer for the housing. There is a trend however to use silicon rubber housing instead. These operate better under harsh environmental conditions and high temperatures, particularly important for high-voltage and remote utility applications. Consult the Dow Corning website, for a comparison of silicon rubber to organic polymer.
