Angle Rings & Caps
Made of transformerboard
According to IEC 60641 - 1 Type B 4.1
The use of angle rings and caps of TRANSFORMERBOARD relieves the electrical stress on adjacent oil channels and increases the partial discharge inception voltage. They are dimensionally stable and thus can be quickly and safely installed as a 360° component. The radii can be chosen so that they correspond as closely as possible to the electric field pattern.
