DISC INSULATOR - WBSETCL
WebThe insulation material states that porcelain has a very high dielectric strength as compared to air. An insulator is designed in a way so that it would flash over just before it’s punctured. A failure because of flash over is usually temporary as well as self-restoring. But a failure because of insulation puncture is always permanent and ... WebMar 22, 2024 · As the rating of each disc insulator is 11 kV, for an 11 kV transmission line the disc insulator required at each pole is 1. Therefore, the total number of insulators used in a transmission line having 80 poles is = 1 × 80 = 80. For three phases, the total number of disks required = 80 × 3 = 240. WebSep 22, 2016 · A Suspension Insulator is basically a string of number of porcelain disc connected in series though metallic link. It shall be noted that the number of discs in Suspension Insulator can be increased or decreased by adding extra discs or removing a disc.
