11kv 1000 Kva Oil-cooled Distribution Transformer

Definition:
An electrical device that transfers energy from primary to secondary distribution systems by stepping down voltage levels (typically 10kV-35kV to 100V-1kV) for safe end-user consumption.

Key Role:
Ensures stable, efficient power distribution across residential, commercial, and industrial networks.

Core Features

Applications by Sector

1. Residential

• Function: Steps down to 120V/230V for households

• Use Cases:

• Powering lighting, appliances, HVAC

• Suburban pole-mounted units (50kVA-300kVA)

2. Commercial

• Function: Supplies 208V/400V for mixed loads

• Use Cases:

• Shopping malls (500kVA+ oil-immersed)

• Hospitals (cast-resin for fire safety)

3. Industrial

• Function: Delivers 480V/690V for heavy machinery

• Use Cases:

• Factory production lines (2.5MVA+ with ONAN cooling)

• Mining operations (explosion-proof designs)

4. Infrastructure

• Function: Powers public utilities

• Use Cases:

• Street lighting (25kVA pole-top)

• Railway signaling (100kVA with ±5% voltage adjustment)

5. Renewable Energy

• Function: Grid integration of solar/wind power

• Use Cases:

• Solar farm step-up (33kV/0.8kV, 1.6MVA)

• Wind turbine pad-mounted (66kV/11kV, 5MVA)

Technical Differentiators

• Materials: Grain-oriented silicon steel (CRGO) cores for ≤1.0W/kg losses

• Cooling: ONAN (oil) for ≤1MVA, OFAF (forced air) for higher capacities

• Smart Features: Optional IoT sensors for real-time load monitoring

Standards Compliance

Why This Matters for Buyers

• Cost Savings: High-efficiency models reduce lifetime OPEX by 20-30%

• Reliability: <0.5% failure rate in first 10 years (industry benchmark)

• Future-Proofing: Compatible with smart grid upgrades
