The characteristics of Silicone rubber post insulators
◆ Cantilever (bending) failure load, torsional and compression failing load - KN
◆ Lightning Impulse Withstand Voltage (BIL) – dry or wet- KV
◆ Height –mm
◆ Nominal Creepage Distance –mm
◆ Fixing Arrangements for top and bottom end fittings
◆ Color: red or grey, customer’s requirements
◆ For transmission applications requiring a BIL greater than 450kV

Silicone rubber post insulator can manufactured, designed and tested in accordance with ANSI C29.9, AS 4398.1 standard, we can reference:
◆ Insulator type
◆ Mechanical strength
◆ Creepage distance value
◆ Lightning impulse withstand voltage

Silicone rubber post insulator is generally designed in cylinder shape form used on outdoor power systems with the high mechanical strength.
