3-Coil Steatite / ceramic / porcelain connection fitting threaded 25mm2, white, ONKA, made in Turkey

Steatite (artificial porcelain) - Used to make insulating parts that have greater electrical and mechanical strength than conventional porcelain materials.

Advantages over ceramics:
- Higher mechanical strength,
- greater dimensional stability,
- Higher temperature resistance (1000 0C and more).
- Greater resistance to acids,
- longer service life,
- It has an insulating surface and the surface electrical leakage is zero, this material is more efficient.
