01 General Overview: Namibia 20 MW PV Power Station Project1.1 Project BackgroundNamibia possesses some of the world’s best solar resources, with average Global Horizontal Irradiation (GHI) exceeding 2400 kWh/m². However, PV plants are often located in the central plateau and arid regions where the natural environment is extremely harsh. The project sites are situated at altitudes between 1500m and 2000m and exposed to IEC 60721-3-3 Class 3S4 environments (Severe Sand and Dust).In the

Project OverviewThe 22kV industrial park in Bac Ninh Province, Vietnam, hosts numerous electronics and precision machining enterprises. The original vacuum load break switches (LBS) accelerated in aging due to high temperature, high humidity, and coastal salt spray, lacking online monitoring and resulting in an average annual O&M cost of $12,000 USD. Undetected internal arcing once triggered a distribution trip, halting production lines across multiple factories and causing over $60,000 USD

Project OverviewA 18kV distribution network in an industrial park previously operated over 30 vacuum load break switches (LBS) that suffered from a lack of full-lifecycle management. Issues included improper selection for industrial pollution environments, sub-standard vacuum interrupters, non-standard installation, and reliance on manual inspections. Within two years of commissioning, arcing and contact overheating were frequent. In 2023, a single unit failure due to vacuum attenuation caused a
