What is the difference between pin post insulator and pin insulator?
Pin type insulator is used in power distribution lines of medium voltage insulator, applicable for 6 kv - 36 kv voltage level. Common pin type insulator divides into composite pin insulator and ceramic pin insulator. According to the ANSI standard, pin insulator is divided into the ANSI 55 series and ANSI 56 series. Pin insulator through in steel foot fixed on the cross arm, at the bottom of the thread and steel chains. The pin insulator way of binding wire has cable tie and tie line two sides.
Porcelain Pin post insulator is used in transmission and distribution lines. Combined with pin insulator and the advantage of pin post insulator, pin post insulator can be applied voltage level is higher than pin insulator. Different from post insulator, the bottom of the pin post insulator umbrella skirt is curved. Pin post insulator for a maximum of 72.5 kv voltage level. Pin post insulator top is same with pin insulator, tie line way also is essentially the same.
The difference between pin insulator and pin insulator is mainly applied voltage grade and shape. Because of the pin post insulator to use in high voltage power transmission and distribution lines, so do it by increasing the parameters such as distance, nominal distance to meet the requirements of voltage. The pin insulator used in medium voltage power distribution lines, it is our one of the most common type of insulator in our daily life.
