1. Project Background
Indonesia's equatorial climate (humidity >80%, temperature 25-32°C) imposes extreme challenges on electrical infrastructure, especially High voltage Disconnect Switches used in transmission networks. Key risks include:
1.1 Biological Erosion
Mold: Degrades insulation in High voltage Disconnect Switch housings, increasing leakage currents.
Insects: Termites/booklice infiltrate gaps ≥0.2mm in switch enclosures, causing mechanical jams or cable damage.
1.2 Infrastructure Demand
National projects (e.g., Jakarta-Surabaya High-Speed Rail) require ultra-reliable power systems. Traditional High voltage Disconnect Switch gear in Sumatra/Kalimantan shows 40% higher failure rates, escalating maintenance costs.
