ANSI 57-35 porcelain line post insulator is Puncture-proof design, no cement growth problem and applied standard ANSI C29.7, and it is braced line post insulator with Curved Base.
For our ANSI 57-35 porcelain line post insulator, we also use high-strength porcelain in accordance with the standards IEC, ANSI and C130. During manufacturing these braced line post insulator products are produced as a single piece unit. The advantage of porcelain line post insulators lies in achieving high mechanical resistance in addition to their electrical insulation capability.

The design of clamp top line post insulator is affected decisively by the ANSI C29.7. Orient also can manufacture insulators as per requirements of our customers and depends strongly on the environmental conditions of their future location. Based on decades of experience and latest manufacturing methods Orient Power can also produce unusual geometries for porcelain insulators.
It is common for transmission and distribution circuits constructed with ANSI 57-35 porcelain line post insulator. This armless construction, using braced line post insulator, permits the construction of sub-transmission and transmission lines on narrow rights-of-way and along city streets.
