All Lapp station post insulators meet ANSI leakage requirements. Lapp also offers high leakage and extra high leakage catalog versions of Lapp station post insulator catalog items.
Lapp station post insulators can be made of silicone rubber materials, which is one of polymer insulators used for stations and substations.
The design features of Lapp station post insulator catalog
◆ All station post insulators have externally attached system transfers the load uniformly from the hardware into the polymer body.
◆ Uniform leakage path
◆ Excellent silicone rubber shed
◆ “straight-line” flashover
◆ Standard bolt circles
