Medium Voltage Outdoor Applications
Tridelta has a long tradition in the production of distribution arresters. Our first medium voltage arresters were produced in 1962.
The housing of these valve-type arresters was generally porcelain. Since 1996 our medium voltage arrester are made only using light and cost-effective silicone housing; they have passed the 5000h ageing test successfully.
Different creepage distance variants and a wide range of connectors and accessories allow customized solutions – please contact us!
