Power Distribution Project of Tanzania Sapphire Float Glass Industrial Park

The Tanzania Sapphire Float Glass Industrial Park is a benchmark project under China’s Belt and Road Initiative. The glass manufacturing process imposes extremely stringent requirements on power supply continuity, power quality and voltage stability. Meanwhile, the park features complex operating conditions including high temperature, high humidity, dust and tin fog corrosion, which pose severe challenges to the corrosion resistance and long-term operational reliability of power distribution equipment.

In terms of structural design, this project adopts a separated layout of relay protection devices and switchgear. Current signals from outgoing units are routed to external connection boxes and then transmitted to relay protection devices in the control room, facilitating centralized monitoring and management. The cable compartment door of the switchgear features an outward extension design, reserving ample space within the cable compartment for convenient installation of various sensors and cables.

In terms of operational performance, ASNA switchgear maintains sufficient temperature-rise margin at rated current, enabling stable operation under high-temperature thermal radiation conditions in the workshop. ASNA switchgear adopts a unique atmospheric sealed Natural Air insulated structure to effectively isolate ambient dust, keeping the insulation performance of the switchgear unaffected and ensuring long-term safe and reliable operation of the power supply system.
