IEEE 1898-2016

The standard describes the terms and definition, use condition, technical requirement, and test methods of composite post insulators for high-voltage direct-current (HVDC) power transmission systems up to A?800 kV. This standard applies to outdoor and indoor composite station post insulators used in HVDC power transmission systems. The composite station post insulators covered by this standard consist of a load-bearing insulating core (or tube), a housing (outside the insulating solid core or tube) made of elastomer material (e.g., silicone or ethylene-propylene), and end fittings attached to the insulating core (or tube). This standard covers the following three types of post insulators: a) Composite post insulator with a ceramic core; b) Composite post insulator with a resin impregnated fibers solid core; c) Composite gas-filled hollow post insulator
