Extruded insulated hard copper bars: Anti-earthquake and impact resistant extruded hard copper bars protect your power system

In the fields of new energy, industrial automation, rail transit and various high-power power transmission, the safety and reliability of power connections are crucial. Traditional bare copper bars may face risks of short circuit, oxidation and mechanical damage under complex working conditions. We focus on providing high-performanceExtruded insulating hard copper bar, especially those with excellenceSeismic and impact resistanceabilityextruded hard copper bar, provide indestructible protection for your critical power systems.

Why choose extruded insulated hard copper bars?

Extruded insulating hard copper barBy integrating high-purity hard copper conductors with high-performance insulating materialsextrusionForming allows it to maintain excellent electrical conductivity while obtaining reliable electrical insulation and mechanical protection. This innovative design brings multiple core advantages:

• Excellent electrical insulation: The extruded insulating layer tightly wraps the conductor, effectively isolating the high-voltage live parts and completely eliminating safety hazards such as short circuits and electric shock. Compared with traditional heat-shrink sleeves or wound insulation, the extruded layer is more uniform and dense, provides more reliable dielectric strength, and remains stable in high-humidity and high-pollution environments.
• Excellent earthquake and impact resistance: The hard copper bar itself has good mechanical strength, while the uniform and elastic extruded insulation layer can effectively absorb and buffer external vibration and impact. This structure can significantly reduce fatigue fracture of copper bars, damage to insulation layers or loose connections caused by mechanical stress, and is especially suitable for scenarios with harsh operating environments such as new energy vehicles and rail transit.
• Excellent environmental resistance: Extruded insulation materials usually have excellent resistance to high temperatures, low temperatures, damp heat, salt spray, oil and ultraviolet light. This allows extruded insulated hard copper bars to work stably for a long time in various harsh industrial or outdoor environments, extending the service life of the equipment.
• Improve space utilization: Because extruded insulation provides reliable electrical isolation, allowing for smaller electrical clearances, it helps achieve a more compact and high-density design inside the device and increases power density.
• Simplify installation and maintenance: Copper bars that have been insulated in advance reduce cumbersome insulation operations on site and improve installation efficiency and safety. At the same time, its maintenance-free features also reduce long-term operating costs.
• High conductivity and low energy consumption: The selection of high-purity electrolytic copper as the conductor substrate ensures extremely low resistivity and efficient current transmission, effectively reducing energy loss and temperature rise.
