TR202-TR214 post insulators are manufactured, designed and tested according to ANSI C29.1 and C29.9 standards. TR202-TR214 post insulators include TR202, TR205, TR208, TR210 and TR214 used on substations, also known as post isolator.
TR202-TR214 post insulators post insulators are recommended for all normal duty switch and bus applications. The advantages of TR202-TR214 post insulators
◆ TR series post insulators are made by porcelain consisting high strength porcelain core
◆ One main kind of solid core insulators
◆ The best features of TR202-TR214 post insulators are combined, resulting in high mechanical strength
◆ Excellent electrical behavior under polluted conditions
The mechanical strength for TR202-TR214 post insulators application
Extra-high strength station post insulators are available for switches to heavy mechanical loads. They are also useful for long or heavily loaded bus runs in substations where severe short circuit stresses could damage insulators with lower ratings.
TR202-TR214 post insulators are made from porcelain which is one main of porcelain station post insulators manufactured by Orient Power China.
