30kV 10kA Porcelain Lightning Arrester

30kV 10kA Composite Polymer Surge Arrester, also called Silicone Lightning Arrestor or Silicone Rubber LA.
They come under the category of Surge Protection Device or Lightning Protection Device. As per IEC:60099 or IS:15086 IS:3070 (latest amendement)
Suitable for application on 33kV overhead power/ electrical/ energy/ high voltage distribution/ transmission lines or systems and substations.
Lightning arresters are used for protection of incoming and outgoing lines, power transformers, and other electrical equipment from lightning surges and power frequency overvoltage. They are a pivotal element in the electrical system’s security framework, protecting numerous electrical devices and preventing disastrous damages and power outages. The installation location is often determined by the type and size of the electrical network, as well as the specific protection requirements. Regular maintenance of lightning arrestors is crucial to ensure their reliability and longevity. Maintenance procedures may include periodic inspections for physical damage, contamination, or degradation. In addition, electrical tests, such as insulation resistance tests and current leakage tests, may be performed to assess the arrestor’s functionality.
