TYPE 510 Porcelain Pin Insulators – Key Features
Superior Electrical Performance – The TYPE 510 Porcelain Pin Insulators deliver reliable electrical performance for 400-3000V systems. With a dry flashover voltage of 55kV and a wet flashover voltage of 25kV, it effectively reduces the risk of flashover and guarantees safe operation under various environmental conditions. Testing and verification follow AS/NZS 2947.1 – Test methods for insulator units where applicable.
High Mechanical Strength – With a minimum cantilever failing load of 7 kN, the insulator reliably withstands conductor tension, wind loads, and ice accretion, ensuring long-term stability in overhead line installations. For installation best practices, refer to our Insulator installation guide for overhead lines.
Cordeau Thread Design – The drawing specifies a “cordeau thread”. This specialized rounded thread profile is commonly used in European and French-standard overhead line applications, providing a secure and reliable mechanical connection to the supporting pin.
Simple Structure, Easy Installation – The pin-type insulator features a one-piece porcelain body designed for convenient mounting on standard pins. The conductor is secured in the side groove or on the neck of the insulator using standard binding methods.
Reliable Design – Engineered for long-term reliable operation with minimal maintenance requirements – regular visual inspections and cleaning are typically sufficient to ensure continued performance.
