Composite vertical line post insulator with pin

Composite vertical line post insulator with pin consist of a cylindrical solid insulating core, bearing the mechanical load, protected by an elastomer housing, the loads being transmitted to the core by metal fittings.

Composite vertical line post insulator with pin specifications:
Silicone rubber housing and core rod are tightly integrated, so accidents caused by interface electrical breakdown are avoided.
With special colloid installation and compression joint technique in the connection of fiberglass epoxy resin lead-out rod and hardware fittings, composite insulators have advantages of high mechanical strength, nice figure, small volume, less weight.
Another advantage is that the hardware plated with zinc to resist erosion can be interchanged with porcelain insulator.

Despite these common features, the materials used and the construction details employed by different composite insulator manufacturers may be different. We propose to use corona ring at 110kv and above corona ring is necessary at 220kv and above different end fitting types are available on request.

Composite vertical line post insulator with pin common types: ANSI 57-1, ANSI 57-2, ANSI 57-3, ANSI 57-4, ANSI 57-5, ANSI 57-6, ANSI 57-11, ANSI 57-12, ANSI 57-13, ANSI 57-14, ANSI 57-15 and ANSI 57-16. For application beyond the range listed here, please contact us for details.
