High voltage polymeric post insulator

Polymeric post insulator can be used in heavy contamination areas and made from silicone rubber with high creepage distance for 10kv to 1000kv AC and DC electrical systems.

Polymeric post insulator

Compared to porcelain or glass insulator, the advantages of Polymeric post insulator
◆ Good pollution performance
◆ High mechanical tensile load
◆ Large span and compact lines
◆ Insulator flashover voltage increased by 30% -50% higher than the same level of porcelain and glass insulators
◆ Used in -60℃ - 200℃ ambient temperature with stable performance
◆ Non-punch-through type design, operating without measuring the zero value
◆ Excellent electrical properties,
◆ High mechanical strength
◆ Epoxy glass rods provide 2 times higher than ordinary steel, is 8 to 10 times higher strength than ceramic materials

Polymeric post insulator has tolerance pollution performance, good performance and good stain resistance. The wet withstand voltage is 2 to 2.5 higher than porcelain materials in same creepage distance.
