Aislamiento de electrodos «JJD005407830» de De Dietrich

This is an electrode insulation component, identified by the manufacturer code JJD005407830 and catalogue article 336.283.001. Parts of this type serve as the ceramic or refractory insulator that electrically isolates the electrode rod from the burner housing or mounting plate. In the ignition and flame-proving system, the insulation must withstand the high temperature of the flame zone while maintaining a stable dielectric strength to prevent leakage current that would weaken the spark or distort the ionisation signal. Selection of such an insulator depends on its outside diameter, overall length, and the shape of the bore or slot that accommodates the electrode; these dimensions must match the electrode assembly and the burner’s spark gap geometry. Typical failure modes include cracking from thermal shock, carbon tracking across the surface, and chipping at the tip where the electrode emerges. When replacing an electrode insulator, the technician should also inspect the electrode tip for erosion and verify that the gap between electrode and burner earth is within the range specified by the burner manufacturer. The catalogue reference and manufacturer code allow direct cross-referencing with the original burner parts list.
