- Hollow insulators can have a cylindrical, conical, or bulbous shape
- Overall length: single-piece 2800 mm/sectional up to 6000 mm
- Production and design entirely based on customer requirements and the local conditions
- Unusual geometries can also be produced
- Completely recyclable
- Service life of up to 60 years
Industry solution: OEM
- Circuit breakers (live tank breaker, dead tank breaker)
- Current transformers, voltage transformers, surge arresters, feed-throughs
Masters of adaptation to their environment
High-strength alumina porcelain C130 is also used for our ceramic hollow insulators. During manufacturing, these products can have a cylindrical, conical, or bulbous geometry, and lengths of up to 2800 mm for single-pieces.
The design of these hollow insulators is heavily influenced by customer requirements and depends on the environmental conditions at the future place of application. Thanks to our decades of experience and the latest manufacturing methods, even unusual geometries pose no problem for LAPP Insulators.
