COPPER BUSBAR SYSTEM

COPPER BUSBAR SYSTEM
The copper busbar bending system refers to the high-current line which is rear part of transformer secondary, and the custom copper busbar is composed of water-cooled cable compensator, water-cooled copper tube group, large-section water-cooled cable,electrode arms and graphite electrode. The grounding copper busbar does not includes electrode arms and graphit electrodes.

Copper busbar system also named as high current line refers to secondary side outlet copper pipe of transformer for EAF, LF, SAF, is consists of compensator group, through-wall copper pipe group, water-cooled busbar, water-cooled cable, conductive electrode arm, and graphite electrode etc. Between the beginning end of water-cooled copper bus pipe and secondary outlet copper bus pipe of transformer, using flexible strand cable compensator, may released influence of heat expansion, electro-power for fixed parts, for sustaining points of through-wall copper pipe group, copper grounding bus bar and water- cooled cable all bearing by bracket of non-conduct magnetic stainless steel, also use insulation parts for liner.

DESIGN
COPPER BUSBAR DESIGN
Several copper busbar designs now exist for the electrode arm and bus-bar assembly. Many older furnaces utilize an arm structure that supports an electrically insulated bus-bar. The electrical copper busbar provides the electrical connection between the power cables and the electrode holder. The copper busbar material is a rigid, round, copper pipe. Typically the copper bus bar for sale is supported by one or two bolted connections. Good insulation must be installed between the bus tube and its' supporting members to ensure that arcing which could destroy the bust tube does not take place. Bus tubes are usually attached to the power cables using removable, cast copper terminals or in some cases, permanent fabricated copper terminal plates and pads.

CONFIGURATION OF COPPER BUSBAR FOR SALE
COPPER BUSBAR CONFIGURATION
Several configurations are available for the copper bus pipe termination at the electrode holder and contact pad. These include flanged connection to the contact pad, flat blade joined to the tube for parallel connection with the holder and a round copper tube contact point with the connector. The copper grounding bus bar may be bolted to the holder or contact pad or a fused permanent joint may be used. Many modern types of steel making furnaces utilize current conducting arms in which the arm itself transmits electricity to the electrode holder and contact pad. Current conducting arms are usually fabricated from copper clad steel or aluminum alloys. Due to the reduced weight of conducting arms as opposed to conventional arm and copper ground busbar assemblies there is somewhat less mechanical wear. However, many of the same maintenance issues apply both to bus tube assemblies and current conducting arms.

BENEFITS OF COPPER BUSBAR SYSTEMS
Copper bsbar system can improve the current distribution inside the EAF electric arc furnace, SAF submerged arc furnace ensure good heat uniformity, improve furnace efficiency, and also reduce the occurrence of electrode slip and erosion. In addition, custom copper busbar auxiliary power supply technology can also be considered for long-term energy conservation and pollution reduction.

ALUMINUM BUSBAR VS COPPER BUSBAR SYSTEM
Copper ground busbar has high conductivity, less loss, is not easily damaged, a long life span, is less affected by temperature changes, and is more suitable for high-power and strong current scenarios. The copper bus bar for sale is durable, retains value, has good conductivity, and high mechanical strength, but it is relative cost-expensive;

Aluminum copper busbar have lower conductivity than copper busbar, relatively shorter lifespan, poorer stability than copper, and are more susceptible to external interference such as temperature and humidity. They have a larger volume compared to copper busbar, but aluminum basbar has lower cost and should be selected for scenario applications.

GUIDE FOR COPPER BUSBAR SELECTION
The copper busbar selection should be based on the amount of the current used, the inductance value, the strength of the custom copper busbar structure, the length and weight of the water-cooled cable structure, make it compatibility with the transformer, and the applicability of the working conditions.

COPPER BUSBAR USES
Uses of copper ground busbar system, usually have to consider other furnace spare parts, such as transformer capacity, electrode regulators, water-cooled cables, copper joints, water-cooled cables, compensators, conductive electrode arms, electrode clamp rings, copper contact, clamping cylinders, disc springs, insulation materials, high-voltage resin insulation hoses, copper steel composite plates.
