Description
The insulators are divided into classes C4, C6, C8, C10 and C12.5 by bending load of 4–12.5 kN. For example, C10-150 has BIL 150 kV, a creepage distance of 660 mm, a height of 355 mm and mounting of 76 mm / 4×M12. The highest, C4-550, at BIL 550 kV has a creepage distance of 3075 mm and a height of 1220 mm. The insulators are made to IEC 60273 in outdoor design, including line post types.
