Fig 9.16 shows the equivalent circuit of a string of suspension insulators containing 4 units. The figure below shows a three-disc string of suspension insulator. Suspension insulator string (the vertical string of discs) on a 275 kV suspension pylon. Porcelain A30 bus insulators have a six-inch (6”) diameter to meet greater mechanical needs.

Suspension insulators also known as Strain insulators, are employed for the rated voltage of 35~500kV AC energy method in frequent and dirty areas, overhead transmission and distribution lines and substations with a frequency not exceeding 100Hz for drape and tensile strength.

In this case, the suspension string is arranged horizontally and the insulator discs are in vertical plane. These pieces of glass have been positioned on a tapered wooden pin, vertically extending upwards from the pole's crossarm (normally only two insulators to a pole and possibly one particular on leading of the pole itself).
String efficiency becomes 100% if the voltage across every single disc is precisely the identical, but this is an best case and not possible in sensible scenario. Meister International maintains an in depth stock of market typical porcelain A30 bus insulators to enable prospects prevent lengthy lead occasions.
In addition to offering the highest-good quality porcelain A20 & A30 bus insulators, Meister International supplies higher-strength porcelain bus insulators where larger mechanical strength is essential. ISO 9001:2008 & AS 9100B certified manufacturer of normal & custom suspension insulators.
