The SB350 Large Power Equipment Wiring Harness is an ultra-high-current, industrial-grade integrated wiring harness designed for heavy-duty industrial power equipment, large-scale energy storage systems, engineering machinery power systems, and high-power DC power distribution equipment. With a rated current of up to 350A, this wiring harness is a high-power professional connection solution tailored for high-current, high-load, and long-term continuous working industrial equipment, solving the problems of insufficient current-carrying capacity, easy heating, poor stability and short service life of ordinary wiring harnesses in high-power equipment. It is widely used in large industrial inverters, heavy engineering vehicles, container energy storage power stations, and high-power power supply equipment connection.

The core wire body of the SB350 high-power wiring harness adopts ultra-large gauge high-purity oxygen-free copper dense stranded wire, which is the highest standard configuration in the industry for high-current power transmission. The oxygen-free copper material has extremely low resistivity and ultra-high conductivity, which can meet the stable transmission demand of 350A ultra-high current for a long time. The dense multi-strand stranded structure makes the wire core have excellent flexibility and current dispersion performance, avoiding local current concentration and overheating of the wire core during high-power operation. Compared with ordinary wiring harnesses, this product has lower line loss and higher transmission efficiency, and can maintain stable power output under long-term full-load and overload working conditions, without power attenuation and line heating failure.

The wiring harness adopts a multi-layer composite protection structure, including inner insulation layer, buffer tensile layer, and outer wear-resistant and flame-retardant sheath. The inner insulation layer is made of high-voltage resistant cross-linked polyethylene material, which can withstand high DC voltage and ensure zero leakage of line insulation. The middle buffer layer increases the tensile and anti-extrusion performance of the wiring harness, avoiding wire core damage caused by external extrusion and stretching during equipment operation and installation. The outer sheath is made of industrial-grade super wear-resistant silicone rubber material, which has ultra-high temperature resistance (-50°C to 120°C), flame retardancy, corrosion resistance, and mechanical damage resistance. It can adapt to harsh industrial environments such as high temperature, dust, oil pollution, and mechanical vibration.

The SB350 high-current industrial connector matched with the wiring harness is forged with thick pure copper and plated with thick silver on the surface, which greatly reduces the contact resistance of the interface and completely solves the common heating and burning problems of high-current connectors. The connector shell is made of high-strength flame-retardant engineering plastic, which is not easy to deform and burn at high temperature. It is equipped with a heavy-duty mechanical self-locking structure, which has super anti-vibration and anti-loosening capabilities, and can maintain stable connection in the long-term vibration working environment of industrial equipment. The sealed waterproof and dustproof structure improves the environmental adaptability of the connector and avoids terminal corrosion and poor contact caused by industrial dust, moisture and oil gas erosion.

In terms of application fields, the SB350 large power equipment wiring harness covers all kinds of ultra-high-power industrial DC power equipment. It is suitable for power connection of container large-scale energy storage power stations, industrial high-power inverters and rectifiers, heavy-duty electric engineering machinery, mining electric equipment, and marine high-power power supply systems. It can realize series-parallel connection of large-capacity battery packs and high-power power transmission between power supply equipment and load equipment. The integrated wiring harness design integrates wiring, insulation and protection into one, which simplifies the complex wiring structure of industrial high-power equipment, reduces the failure rate of line connections, and facilitates equipment installation, maintenance and troubleshooting.

This industrial-grade wiring harness has passed strict industrial heavy-load testing and certification, including 24-hour continuous 350A full-load aging test, high and low temperature cycle test, mechanical fatigue vibration test, and salt spray corrosion test. The product has extremely high working stability and durability, with a service life of more than 10 years in industrial harsh environments. The ultra-low loss power transmission performance effectively improves the operating efficiency of high-power equipment and reduces enterprise energy consumption costs. As a core connection component of high-power industrial equipment, the SB350 wiring harness provides safe, stable and efficient power transmission guarantee for heavy industrial power systems.
