Description

Spare Parts Supply for SAF Short Network System

The short network is a core component of the power supply system in submerged arc furnaces (SAF). It connects the secondary terminal of the transformer to the electrode copper shoe, undertaking the critical task of transmitting high-current electrical energy into the furnace. The design and manufacturing quality of the short network directly affect the power efficiency, three-phase balance, and operational stability of the SAF.

1. Definition
The short network refers to all conductors from the secondary terminal of the furnace transformer to the electrode copper shoe (heating terminal). It is named for its short transmission distance (typically only a few meters to over ten meters)

2. Specifications and Parameters

Parameter Specification Range
Cross-section Shape Circular / Rectangular
Rectangular Section Size Depends on the current level
Center Phase Spacing Around 30mm
Outer Phase Spacing Around 5mm
Resistivity 0.0175 Ω·mm²/m (20℃)


3. Key Supporting Components

Component Description
Compensator Connects transformer to fixed copper tube, absorbs thermal expansion and installation errors; Type A, B, C connectors available
Conductive Copper Tube Fixed section copper tubes, multiple parallel connections, rectangular cross-section reduces reactance
Water-Cooled Cable Connects fixed copper tube to movable furnace copper tube; flexible and bendable to accommodate electrode lifting
Cable Management Mechanism Clamps, fixing grooves, adjustment sleeves, etc., prevent cable tangling and reduce water flow resistance
Insulation Clamp Fixes multiple copper tubes, maintains consistent spacing, prevents short circuits

4. Selection Recommendations

SAF Capacity Recommended Configuration Selection Reason
Small Furnace (<12500kVA) Circular Cross-Section Copper Tube + Braided Water-Cooled Cable Lower cost, meets basic requirements
Medium Furnace (12500-35000kVA) Rectangular Cross-Section Copper Tube + Braided/Stranded Cable Reduces reactance, improves efficiency
Large Furnace (35000-81000kVA) Rectangular Cross-Section Copper Tube + Low Impedance Design + LV Short Network Compensation Pursues optimal energy saving effect
Ultra-Large Furnace (>81000kVA) Equilateral Triangle Transformer Arrangement + LV Short Network Compensation Three-phase balance, reduces line losses

Notes:1. Rectangular cross-section copper tube reduces phase spacing, increases mutual inductance, and lowers reactance; cut-surface adjacent arrangement provides optimal effect
2. Insulation treatment must be enhanced when short network spacing is reduced to prevent short circuit accidents
3. Ensure cooling water flow rate and water quality meet requirements to prevent scaling and blockage
4. Conductive tube temperature inside the furnace is 300-400℃ higher than outside, requiring larger cross-section or enhanced cooling
