Applications
In power transmission and distribution systems, surge arrester insulation brackets are used in a variety of applications. Listed below are some of the common places used:
In substations, Surge Arrester Insulation Brackets are used to support and insulate surge arresters protecting critical equipment such as transformers, circuit breakers and busbars from lightning and switching transients.
On transmission lines, these brackets are used for the installation of surge arresters on towers and pylons to provide protection against lightning induced surges that can travel along the lines and cause damage to equipment and disruption of power flow.
In distribution systems, overvoltage arrestor holders are used for mounting overvoltage arrestors on distribution poles and structures. This helps to protect residential, commercial and industrial customers from overvoltage conditions that can damage electrical appliances and equipment.
Surge Arrester Insulation Brackets are used to secure surge arresters that protect inverters, transformers and other sensitive equipment from voltage spikes in renewable energy installations such as wind farms and solar power plants.
Industrial facilities with large electrical systems use surge arrestors to protect motors, generators and other machinery from surging voltages that could cause equipment failure and production loss.
In rail electrification schemes, surge arrestor supports are used to install surge arrestors along electrified tracks and in substations to protect rail electrical infrastructure from lightning and switching overvoltages.
Telecom towers use surge arrestor holders to secure surge arrestors that protect communications equipment from lightning surges, ensuring reliable communications services.
These places of application illustrate the versatility and importance of the surge arrester isolation bracket in helping to maintain the reliability and safety of a variety of electrical and electronic systems.
