Cavo di accensione De Dietrich 97955556: L280 mm (2x)

This De Dietrich 97955556 ignition cable is 280 mm long and supplied as a pair of cables. It belongs to the type of high-voltage silicone-insulated leads that connect the ignition transformer to the spark electrode. In a burner system, the transformer produces a high-voltage pulse during the ignition phase, and the cable conveys that pulse to the electrode gap. Cables of this class are built with silicone insulation because it withstands both the elevated voltage and the heat radiated by the burner head and combustion chamber. Selection of such a cable is based primarily on length, terminal design, and connector pattern to match the electrode and transformer fittings. A hardened, cracked, or carbonised cable can leak the spark voltage to ground, which often presents as a weak or absent spark and may be mistaken for a faulty transformer. When replacing, it is good practice to inspect the cable condition together with the transformer and the electrode. The two-cable set is typical for burners that use separate ignition and ionisation electrodes, or for dual-electrode ignition layouts. This specific article is branded De Dietrich and carries the manufacturer codes 97955556 and 336.292.001. The stated length of 280 mm should be verified against the physical distance between the transformer terminal and the electrode in the appliance to be serviced, as no further compatibility information is provided in the source data.
