Notes:
All section lengths are based on Y-Clevis & Ball, Socket & Ball, Oval Eye & Ball, Oval Eye-Oval Eye end fittings, or Socket Ball and Y-Clevis Ball combinations.
Electrical data shown for insulators without corona rings. Lapp recommends corona rings to be installed at 230kV and above
Additional section lengths and creepage distances are available.
All dimensions, tolerances and tests are within allowable ANSI standards.
All dimensions are in inches and pounds.

Line Post Transmission Insulator:
Rod Diameter 2.5”, Rod Diameter 1.75”

Available End Fittings: Gain Base, Drop Tongue, Flat Base, Horizontal Trunnion: ANSI C29.7, 5” Flange, Vertical Trunnion: ANSI C29.7, Stud Base 0.75”, Stud Base 0.875”, Vertical Trunnion: ANSI C29.7
All section lengths are based on Gain Base & Trunnion end fittings. Mounted horizontally.

Braced Post Insulator:
All braced posts shown with 12°upsweep bendable gain base and standard coupling shackles.
Other hardware combinations are available, contact sales agency for details.
All dimensions, tolerances and testing are within allowable ANSI standards.

Station Post Insulator:
Available End Fittings: 5” Flange, 3” Flange
RCL = Reference Cantilever Load for polymer and is the maximum load the insulator can withstand in service.
It is approximately 50% of the ultimate cantilever rating of each design.
Cantilever shown for porcelain is the ultimate value.
WL = Working Load of porcelain and is approximately 40% of the ultimate rating.

All suspension corona rings are 13.8” OD, Galvanized steel, Open style, Reversible mounting
All line post corona rings are: 13.8” OD, Galvanized steel, Closed Ring style

Corona Rings: 230 kV, 345 kV, 500 kV
