Post insulator definition

What is a post insulator?
A post insulator is one of insulation materials used for supporting and insulating wires or conductors and installed with other assemblies.

The features in post insulator definition
◆ The RIV performance of single post insulator styles will be tested in accordance with the standard IEC60437 upon request
◆ High voltage post insulator should install with grading rings
◆ If corona rings are necessary to reach a certain RIV level for a single insulator column, the appropriate ones will be offered with the insulator column

The mechanical strength for post insulator
◆ Compression strength
◆ Torsion strength
◆ Tensile strength
◆ Cantilever strength

P13 and P70 is popular post insulator made of high aluminum C130 porcelain materials with increased arcing distance, less assembly time and high mechanical strength.
