36kV Polymeric Substation Insulator With Flange

Core Voltage Definition: 72.5kV is the highest system voltage Um.

IEC International Standard Unified Identification

72.5kV = Highest System Operating Voltage (Um), corresponding to nominal operating voltages of 66kV / 69kV.
Europe, Africa, Southeast Asia, Australia: Nominal 66kV, equipment marked Um=72.5kV (IEC standard).
Americas (North and South America): Nominal 69kV, equipment also marked 72.5kV (ANSI/IEEE).
Domestic Corresponding Level: In China's 66kV power grid, the national standard mandates a maximum equipment voltage Um=72.5kV, which is compatible with overseas standards.

35kV(38mm diameter)

Which Foreign Countries Use 72.5kV (66/69kV Lines) in Large Quantities?

1) Europe (Full Coverage of 72.5kV System)
The entire EU, the UK, Turkey, and Eastern Europe use 72.5kV as the mainstream voltage for distribution network backbones and wind farm collector lines. GIS, transformers, and insulators are uniformly designed according to 72.5kV (EN/IEC standards).

2) African Market (South Africa and East Africa, which you focus on)
South Africa, Kenya, Mozambique, and Nigeria: The main regional transmission voltage is 66kV (Um72.5kV). Mines, photovoltaic, wind power, and urban and rural trunk lines almost entirely use this level, resulting in a huge demand for insulators, surge arresters, and cables.

3) Central and South America (Brazil, Peru, Chile, Colombia)
The Americas system is nominally 69kV, but equipment nameplates uniformly indicate 72.5kV. It is standard equipment for mines, hydropower, and long-distance suburban power distribution.

4) Southeast Asia, Australia, Middle East, Vietnam, Thailand, Indonesia, Australia, Saudi Arabia: Large-scale photovoltaic, offshore wind power, industrial park 66kV collection line standard 72.5kV equipment.
