High-voltage cables are an element of the ignition system, the duties of which include the transmission of high-voltage pulses to the spark plugs from the ignition coil. The cables consist of a protective insulating layer to carry high voltage currents, metal lugs for reliable contact with the leads of the ignition coil, and caps that tightly connect the parts of the system.

The principle of the BOSCH brand Ignition Cable work

The ignition system ensures the operation of the car engine and therefore every element is important. For example, a set of ignition cables supplies voltage from a high-voltage coil to the spark plugs, which generate a spark in the combustion chambers. The deterioration of the technical condition of these products will lead to an increase in resistance and the current supplied to the candles will decrease. This will cause the spark to be weak and unstable, leading to engine malfunction and engine wear.

In addition to high requirements for the electrical conductor, attention is paid to its insulation in order to exclude the possibility of destruction and short circuit to the metal parts of the car. It is impossible to make the ignition voltage lower and safer, since when operating at low pulses, there is a possibility of electromagnetic interference, which will negatively affect the operation of the engine.
