Insulators

The secret of the quality of our insulators lies in the smallest but nonetheless important details. This ranges from the mechanical and geometric adaptation of the insulators, to customer-specific requirements, to the patented production methods of the insulators of LAPP Insulators with unique vertical integration. Thanks to the immense global experience of our specialists and researchers each and every one of our insulators can be adapted precisely in detail to the climatic and environmental conditions of each application.
For our ceramic insulators we use high-strength porcelain in accordance with the C130 standard at all locations. Thus we achieve consistent quality for all requirements. The result: Our insulators are unbeatable in resilience, durability and reliability of supply.
Our composite insulators are also dimensioned down to the smallest detail and are tailored specifically to their future tasks – this is confirmed by our test procedures throughout and after the production processes.

Composite advantages compared to porcelain and glass

• Hydrophobic, water-repellent properties, preventing the formation of any contiguous water layer on the insulator surface
• Most reliable performance in high-pollution, desert and sea-side environments
• Lower price range
• Lighter weight
• Easier to install
• Vandalism-proof, non-breaking

Advantages compared to other composite insulators

• 30 years of experience and more than 1,500,000 pieces installed as a reference for reliability
• Extended lifetime due to the high silicon-content LSR rubber coating
• No failures caused by joining problems, since the coating is made in one piece
• No sealing is needed between the metal fitting and the rubber coating, so the failures seen with other composite insulators do not occur.
