The fibreglass strand core is covered by a layer of ferrite magnetic material wound with variable-pitched stainless steel wire. The outer jacket offers excellent insulation and heat resistance made from either;
1. NGK’s silicone insulation – 260°C heat rating
2. NGK’s EPDM rubber compound (Ethylene Propylene Diene Monomer) – 180°C heat rating
3. Polyvinyl Chloride – 100°C heat rating
NGK have selected the most appropriate insulating material to specifically suit each particular vehicle application.
