Transmission suspension insulators:
FRP Composite suspension insulator is lighter than porcelain insulators.
ANSI C29.11 is Tests for Composite Suspension Insulator for Overhead Transmission Lines, and ANSI C29.12 is about Insulators Composites Suspension Type.
Y-Clevis, Eye and Clevis are according to ANSI C29.12.
A ceramic suspension insulator set complete with the fittings is used to carry a line conductor or conductors at its lower end.
U70BL means 70KN ball and socket porcelain disc suspension insulator with 146 section length.
Zinc Sleeve can prevent pin corrosion.

Transmission suspension insulators can be used on high voltage transmission lines, EHV, UHV, HVDC transmission lines. Porcelain transmission suspension insulator and composite transmission suspension insulator have their own advantages and disadvantages.
