The cable net comprises 192 radial cables and 16 circumferential cables. To improve handling, cable diameters were kept below 76mm, while to provide strength, cables are generally installed in pairs, which also facilitates the clamping between radial and circumferential cables.
The radial cables run between the top ring and the concrete plinth around the perimeter. These carry the roof weight as well as the weight of any snow, which is considerable in Kazakhstan winters. The circumferential cables are used to stabilise the radial ones by pulling against them, and they also restrain the roof under wind loads.
