Cofi High-voltage wire 400 mm 09CA036112

This is a ready-to-install high-voltage ignition cable assembly from Italian manufacturer Cofi, designed for gas burner ignition systems. The cable has a specified length of 400 mm, with an actual measured length of 412 mm, and is insulated with silicone to withstand high voltage and heat. It comes with terminals pre-installed, making it ready for immediate use. The cable is compatible with Cofi burners and other models that match its specifications.

When selecting a replacement ignition cable of this type, ensure the length matches the original (typically measured from connector to connector) and that the connector pattern at both ends fits the ignition transformer and spark electrode. The cable must be routed away from sharp edges and hot surfaces to preserve the silicone insulation. Verify the cable's voltage rating and insulation material are suitable for the application.

Ignition cables of this kind can fail due to hardening, cracking, or carbon tracking of the insulation, which allows the high voltage to leak to the burner chassis or electrode holder. This results in a weak or absent spark, often mimicking a faulty transformer or damaged electrode. When an ignition fault is reported, inspect the cable for visible damage or signs of electrical tracking.
