Line arresters are an effective and economical way to protect both existing and new transmission lines from lightning surges, thereby increasing grid security and line availability. Line arresters are particularly suitable for line areas with poor master grounding resistances, areas with increased lightning activity, overhead lines without ground wire protection and for overhead lines with increased requirements for their availability.
Tridelta offers line arresters as NGLA types (Non-Gapped Line Arresters), based on our arresters with silicone housing of the product libe SBKC. They are supplemented by a variety of appropriate connection and mounting options, such as cable clamps, so that easy installation to different pole, insulator and line configurations is possible.
We would be pleased to offer you a solution tailored to your situation, please contact us!
