Flexible Copper Braid Busbar For Electric Furnace
Products Description
The Flexible Copper Braid Busbar for Electric Furnaces is not a soft-connection version of the traditional rigid busbar, but rather a living power transmission system designed for severe thermo-mechanical coupling conditions. In high-power, unsteady-state load scenarios such as electric arc furnaces, induction furnaces, and resistance furnaces, its three-dimensional braided structure, through the coordinated micro-motions of thousands of independent copper wires, transforms destructive stresses such as thermal expansion and contraction, electromagnetic impact, and mechanical vibration into adaptive elastic potential energy. This shift in design paradigm from "rigid resistance" to "flexible symbiosis" allows the product to maintain stable contact impedance and structural integrity even under extreme conditions such as frequent electrode rises and falls, sudden temperature changes of 200℃/min, and short-circuit impact currents reaching eight times the rated value.
Unlike layered structures, the core value of the braided busbar lies in its continuous topology-each copper wire is both an independent current-carrying path and a node in the overall stress network. This decentralized mechanical design fundamentally avoids the risk of interlayer delamination; its fatigue life depends not on the bonding strength of a single interface, but on the coordinated damping capacity of the entire braid. When applied to electric furnace short network systems, it can reduce the failure rate of loose nodes caused by traditional hard connections by more than 90%, while extending the system maintenance cycle from monthly to annual.
Product Properties and Core Features
Highly Flexible Structure Absorbs Equipment Displacement
Electric furnaces experience significant thermal expansion and contraction during heating, shutdown, and repeated operation, accompanied by mechanical vibration and furnace body position adjustments. Braided Copper Ground Straps automatically release stress, preventing rigid busbar breakage, loosening, or interface fatigue.
01
High Current Carrying Capacity
Utilizing high-purity oxygen-free copper wire, the multi-strand braided structure increases the actual conductive cross-sectional area, maintaining low temperature rise under high current, high-frequency impact, and continuous energization conditions.
02
Low Contact Resistance and Low Loss
Excellent surface contact quality and stable crimping process ensure extremely low interface resistance, effectively reducing energy consumption and improving system electrical efficiency.
03
Good Heat Resistance and Oxidation Resistance
Electric furnace environments experience drastic temperature changes. The copper braided structure maintains good conductivity and mechanical strength at high temperatures, and surface anti-oxidation treatment extends overall lifespan.
04
Lightweight structure and flexible installation
Compared with rigid copper busbars of the same current capacity, Copper Braided Connectors with Welded Ends are significantly lighter, making it easier for equipment wiring, installation, disassembly and subsequent maintenance.
05
Design Advantages: Structural Innovation Centered on Electric Furnace Operating Conditions
Vibration-Resistant and Anti-Loss Design
The Copper Braided Connectors with Insulation structure naturally possesses elastic buffering capabilities, absorbing high-frequency vibrations and thermal expansion and contraction stresses during electric furnace operation, preventing joint loosening or conductor breakage caused by rigid connections. The joints at both ends employ a dual fixing process of crimping and welding, combined with an anti-loosening snap structure, maintaining connection stability even under long-term vibration environments, with a near-zero joint detachment rate.
Space-Adaptive Design
Allows for bending at any angle and three-dimensional spatial wiring, with a minimum bending radius of only 3 times Copper Stranded Flexible Connections' own diameter. Perfectly adapts to narrow gaps and irregular layouts between the electric furnace body, transformer, and control cabinet, eliminating the need for custom-shaped connectors and significantly reducing installation space limitations.
Fatigue-Optimized Design
Finite element analysis optimises the braiding density and strand distribution, focusing on strengthening the structural strength of the transition area between the joint and conductor. This allows the product to withstand over 100,000 vibration and thermal expansion/contraction cycles, extending its service life by 3 times compared to ordinary copper braided wire. This significantly reduces the frequency of electric furnace maintenance by more than double.
