Diesel engine heater plug energising coil - uses spiral shaped resistance path located around electrically conducting carrier

摘要

The electric heater plug has compact design, short heat-up time. It is designed for use as a heating element to give very high temps. in a confined space. The resistance path is spiral-shaped and is wound around an electrically contacting carrier, such that the discrete windings of the resistance path are electrically isolated from one another by an insulation layer. The carrier resistance path and insulation layer form a composite body. The resistance path more specif. consists of CrSi2.
