Sub Distribution Panel (SDP)

An SDP (Sub-Distribution Panel), also known as a Branch Distribution Panel, is a low-voltage electrical panel that receives power from the main panel (LVMDP) and distributes it to several smaller load groups or to final distribution panels (Final Distribution Panels / Sub-SDPs) in a specific area.

Main Functions of an SDP Panel

1. Branch Current Distribution (Sub-Distribution)
2. Local Protection
3. Area Load Isolation (Local Isolation)

Advantages of an SDP Panel

1. Simplified Cabling Routes
2. Electrical System Reliability (Preventing Total Blackouts)
3. Space and Cost Efficiency
4. Easier Maintenance and Troubleshooting

How It Works

1. Power Intake
2. Distribution via Branch Busbar
3. Load Distribution
4. Automatic Protection
