Both have taken decades to perfect, and are unrivalled in the industry.Either our latest G7 silver-gold alloy or monocrystal silver conductors are used, depending on the application. This is combined with our advanced multi-layer Kapton-Teflon insulation materials and an external circumferential shield.
