AC and DC high-voltage applications such as cable endings may experience stress concentrations. To avoid this, field-grading materials are used to embed the electric applications.
Saint-Gobain manufactures SiC doped specifically with other elements to achieve certain semiconducting properties. This is embedded in polymer matrices which can be extruded to application specific shapes.
The SiC in these applications is delivered to purity and conductivity specifications defined by each customer’s specific need.
