Ignition cables with inductive resistor

Like carbon resistor ignition cables, these ignition cables have a fibreglass core. Over the fibreglass there is a conductive and magnetic silicone layer, around which a stainless steel wire is wound. Inductive voltage occurs here (electromagnetism) like it does with a coil.

A pulsing magnetic field is generated in these ignition cables. The ignition coil stores energy and then releases it again. As a result, the inductive voltage in the cable is neutralised. Therefore, this is referred to as "reactive energy" and the inductive resistance is referred  o as "reactant". The resistance of such ignition cables fluctuates depending on the engine speed.

Ignition cables with inductive resistor are surrounded by two silicone layers and fibreglass fabric. The inner insulation made of silicone provides for stability and protects against high ignition voltages. The fibreglass fabric increases the tensile strength. The outer insulation, made of silicone rubber, can withstand temperatures up to 220 °C and is resistant to gas and oil.

One meter of this type of cable can have interference suppression of 2.2 kΩ to 8 kΩ.
