Brahma High-voltage wire D5 PD42/P C00700341

This high-voltage ignition cable, model D5 PD42/P from Brahma, is made in Italy. It is designed for burners operating on gas and liquid fuel. The cable has silicone insulation, an actual length of 660 mm, a diameter of 14 mm, and a net weight of 0.027 kg. Its connector pattern is D5 PD42/P, and it is constructed for high wear resistance.

For this type of cable, the connector pattern at both ends must match the transformer terminal and the electrode connector; patterns vary between manufacturers and even between models of the same brand. The overall length must fit the distance between the transformer and the electrode inside the burner housing — too short a cable strains the connections, while too long a cable may touch hot surfaces or cause interference. Before ordering, verify the connector pattern and length against the existing cable.

With age, the insulation on cables of this kind can harden or crack, particularly near the combustion head. A cracked or brittle cable may leak the high-voltage pulse to earth, causing a weak or absent spark at the electrode that can mimic a faulty transformer. Check the cable by flexing it along its length and looking for visible cracks or stiffness.
