Product Description

Conductive Cross Arm

1. Product Overview

Conductive cross arm, also named electrode conductive arm, is the core key component of electrode lifting system for submerged arc furnaces, ferroalloy furnaces, industrial silicon furnaces, calcium carbide furnaces and closed refining furnaces. It integrates two core functions: electrode mechanical support & large-current power transmission, connecting water-cooled cables on one end and electrode clamps on the other end.

Traditional separated short-net structure adopts independent conductive copper tubes plus steel support beams, featuring complex layout, many insulation parts, high circuit impedance, severe heat generation and large power loss. Our integrated water-cooled conductive cross arm adopts copper-steel composite or aluminum-steel composite hollow box structure with built-in circulating cooling water channels. It cancels numerous intermediate conductive and insulating parts, greatly shortens conductive path, reduces skin effect and impedance loss, stabilizes arc operation, and significantly cuts smelting power consumption. It is widely matched with 6,300kVA–63,000kVA full-series metallurgical electric furnaces, the core upgrade part for short-network energy-saving transformation of smelting enterprises.

3. Core Structure & Working Principle

The whole conductive cross arm consists of five core assemblies: composite conductive arm body, internal circulating water cooling channel, rear conductive transition plate, front electrode clamp connecting end and insulated support base.

Composite Conductive Arm Body

Adopts copper/aluminum-steel double-layer composite plate. The copper/aluminum layer undertakes large-current conduction, while the steel layer provides mechanical bearing strength. Hollow rectangular box structure optimizes current distribution and suppresses skin effect.
Closed Circulating Water Cooling Channel

Independent separated labyrinth water channel design eliminates local dead water overheating. Cooling water circulates inside the arm body to continuously take away joule heat generated by high current, keeping arm surface temperature below safe limit, avoiding insulation aging and thermal deformation.
Rear Conductive Transition Plate

Integrally welded thick copper plate, directly connected with water-cooled cable terminals, large contact area, uniform current distribution and extremely low contact resistance.
Front Clamp Connection End

Precision machined mounting surface matched with electrode holder, reliable locking structure, stable clamping force to prevent electrode offset and arc shaking.
Insulated Support Base

High-temperature resistant integral insulation blocks isolate the charged cross arm from the electrode lifting stand column, eliminating electric leakage and short-circuit risks of the whole lifting system.

4. Core Product Advantages

4.1 Low Impedance & Significant Energy Saving

Integrated conductive structure shortens current transmission path, removes redundant intermediate copper tubes and insulating parts, effectively weakens skin effect, reduces short-network impedance by 30%–50%. Smelting power consumption decreases obviously under long-term full-load operation, bringing remarkable economic benefits.

4.2 High Structural Rigidity & Stable Smelting Condition

Hollow box composite structure features strong bending resistance and anti-vibration performance. Electrode lifting & lowering runs smoothly without severe shaking, arc burning is stable, furnace temperature field uniform, alloy composition fluctuation reduced, finished product yield improved.

4.3 Integrated Water Cooling, Long Service Life

Full-surround internal forced water cooling controls overall temperature rise of cross arm, avoids local overheating burnout of conductive layer. Wear-resistant and anti-oxidation surface treatment, service life far longer than traditional separated conductive beam structure, reducing frequent replacement downtime loss.

4.4 Simplified Short-Net Layout, Lower Maintenance Cost

Cancel complex intermediate conductive components, fewer connecting flanges and sealing points; modular split structure allows partial disassembly and replacement without removing the whole cross arm, daily inspection and maintenance more convenient, fewer spare parts consumption.

4.5 Lightweight Design, Small Lifting Load

Aluminum-steel composite model greatly reduces self-weight, lowers output power demand of electrode hydraulic lifting cylinder, prolongs service life of hydraulic station and lifting mechanical parts.

4.6 Safe & Reliable Multi-Layer Protection

Equipped with high-performance insulation assembly between cross arm and lifting frame to prevent electric leakage; optional online water temperature & flow monitoring module, automatic alarm when water cut-off or overheating occurs, effectively avoid equipment burnout accidents.
