This volume gives a fantastic overview. What are the precise details you're after?
The Electric Power Research Institute (EPRI) has an excellent "Transmission Line Reference Book-345 kv and above". You can download the book from EPRI's site
The voltage level described 220 kV is more likely to find in IEC market place countries. Most tower uses in IEC are have some similarities, but also major different in shape, clearance and design parameters than those tower used in the ANSI market place for 230 kV nominal voltage.
If you should be interested on those info check on the T&D Westinghouse Handbook (reprinted by ABB) and the EE Handbook by Fink &Betty.
The selection of a particular design is based on many factors such as project specific requirement, economics, engineering tradition, environment conditions (wind speed, seismic, snow, temperature, etc.)
Some of these tower differences are:
Construction: lattice, tubular, solid section (I-beam), etc.
Materials: steel, aluminum, concrete, wood, composite, etc.
Guided tower, compact arrangement, conventional, single or double circuits with or without under-built
