As a leading professional post insulator manufacturer China, Orient Power manufactures and designs TR216-TR231 Porcelain post insulators which include TR216, TR222, TR225, TR227 and TR231 according to ANSI C29.9 or customers’ requirement.
TR216-TR231 Porcelain post insulators definition
A porcelain post insulator is an insulator of generally columnar shape, having means for direct and rigid mounting and consisting of porcelain units and metal end fittings.
ANSI TR216-TR231 Porcelain post insulators are a high voltage ceramic post insulator for low frequency wet withstand voltage 145kV ~ 225kV outdoor power stations, substations equipment devices made by wet process porcelain with high mechanical strength.
