What is the difference between pin insulator ANSI 55 series with ANSI 56?
Pin type insulator ANSI 55 series using the material is porcelain. Pin insulator ANSI 55 series in shape can be divided into three parts: part at the top of the tie line, middle shed part, below the threaded portion. Pin insulator ANSI 55 series have good antifouling performance. Pin insulator ANSI among 55 series is only one shed, an arc downwards, shed edge to the thread position 2 ridges, it can increase the insulator creepage distance . 55 series insulator cable tie pin insulator ANSI method is at the top of the cable tie and tie line two sides.
Pin insulator ANSI 56 series is made with ceramic materials. The shape of the pin insulator ANSI 56 series has 3 kinds, have in common is the shed is large, curved downward extension. Pin insulator ANSI 56 series on strength and dry performance parameters such as arc distance is higher than pin insulator ANSI 55 series. Pin insulator ANSI 56 series shed generally have two or three; this design makes the form of pin insulator ANSI 56 series than pin insulator ANSI 55 series have better antifouling performance.
Although the pin insulator ANSI 55 pin insulator compare with ANSI compared 56 series parameters have some low performance, but because the pin insulator ANSI 55 series of cheap, have better performance in the normal environment, so users prefer to use one of the insulator. Pin insulator ANSI 56 series in some relatively high voltage, environment relatively complex area has a wide range of applications. Pin insulator ANSI 55 series and pin type insulator ANSI 56 series are used on the distribution line.
