Option 2 : 33 kV

Pin Insulators:

A pin insulator is a device that isolates a wire from physical support such as a pin (a wooden or metal dowel of about 3 cm diameter with screw threads) on a telegraph or utility pole.
Pin insulators are used in electric distribution systems up to 33 kV voltage levels. Beyond operating voltage of 33kV, pin insulators become too bulky and uneconomical.
It is a formed, single-layer shape that is made out of a non-conducting material, usually porcelain or glass.
