Ultra violate Hardened High Voltage Surface Coating
Modern electric transmission line tends to use silicon disk to replace ceramic and class disk to increase the creepage distance of the charges, this has advantage over the former because of its elasticity and easy handling property. The mechanical hardness of these two types is does not bring advantage to its applications any way.
The silicon disk has also relative higher CTI against traditional ones. But an inherent organic characteristic of silicon makes it susceptible to ultra-violate and weather. So, with time its surface CTI decreases. The charges go easily on the silicon surface.
NOVOTRONICS NOVO-ENDURENCE endurance spray treats the surface so that silicon surface withstand the ultra-violate and weather for the life cycle of the disk.
