Screw head insulation - Electrical insulation and mechanical stability
When pinning and screwing components together in industrial applications, it is often necessary to ensure reliable electrical insulation without compromising the mechanical stability of the connection. While ceramic dowel pins ensure positive locking and steel screws ensure the positional connection of the assemblies, thermoset screw head insulators take on the task of electrical isolation.
In contrast to thermoplastic variants, thermoset screw head insulations offer significantly higher compressive strength and do not deform under load. These properties enable a durable, secure and low-maintenance connection in environments where electrical insulation and mechanical strength are required at the same time.
Materials for screw head insulation
Overview of compatible materials
| Material | Properties | Typical applications |
|---|---|---|
DOGLAS | Glass fiber reinforced thermosetting plastics (GRP) with high mechanical strength and electrical insulation | Insulating components in bolted connections, induction environments |
DOTHERM | Materials with low thermal conductivity and excellent electrical insulation, suitable for high temperatures | Electrically insulating applications in high-temperature areas |
DOTEX | Thermoset composite material based on phenolic resin, reinforced with cotton or paper fabrics | Economical solutions for electrical insulation with moderate mechanical loads |
