An overview of our products – our many years of experience and constant, ongoing development pay dividends.
What makes the product expertise of LAPP Insulators so special? The internal production chain, over which we have exclusive control and through which all our products pass, from the original raw material through to the final end product. This lets us keep an eye on everything and take absolute responsibility for our insulators – 100%.
It is the cornerstone that connects the greatest possible reliability and safety, that we guarantee with our products. This ensures that our insulators are durable and always available.
Added value at a glance
Insulators in supreme quality
The secret behind our high-quality insulators lies in the small, but important details. These range from the mechanical and geometric adjustment of the insulators to customer-specific requirements through to the patented LAPP Insulators manufacturing processes. Thanks to our unparalleled level of vertical integration made possible by the immense experience of our specialists and researchers. They allow us to adapt each of our insulators to the climatic and environmental conditions on-site. And that’s precisely what sets our product expertise apart.
For our ceramic insulators, we exclusively use high-strength porcelain in line with standard C130 (IEC 60672) at all sites. This ensures consistent quality for all demands. The result: Our insulators are unbeatable in terms of durability, longevity, and security of supply.
