Post insulator 33kv is one of line insulator or station post insulator used for distribution systems and made from porcelain or polymer.

The features of Post insulator 33kv
◆ System voltage: 33kv
◆ Materials: porcelain or polymer
◆ Installation of insulator: outdoor line support
◆ Leakage distance: 736mm
◆ Power frequency puncture voltage
◆ Impulse withstand voltage
◆ Power frequency flashover voltage etc.

According to insulator designed, Post insulator 33kv can be divided into
◆ Pin post insulator
◆ Line post insulator
◆ Station post insulator

According insulator coupling way, Post insulator 33kv can be divided into
◆ Tie top insulator
◆ Vertical Clamp top insulator
◆ Horizontal clamp top insulator

Post insulator 33kv is generally used with insulator end fittings, such as insulator spindle, insulator stud and flange in accordance with ANSI or IEC specifications.
