The external wiring harness is a key component that ensures the stable operation of the excavator's external electrical system. Its core is composed of multiple strands of high-purity tinned copper core wires, wrapped with high-quality insulation sheaths (such as TPU or special PVC material) that are resistant to oil, high temperature (usually up to -40 ° C to 125 ° C), UV, wear, and flame retardancy. Corrugated pipes or woven mesh pipes have been installed on key areas that are prone to wear and tear for enhanced protection. The wiring harness integrates specialized connectors with waterproof and dustproof ratings of IP67 or higher (such as AMP, TE, and other brands), ensuring stable signal transmission and reliable power supply even in harsh working conditions such as severe vibration, humidity, dust, and oil pollution faced by excavators.
 

Regular inspection and maintenance are crucial to ensure the long-term reliable operation of the external wiring harness. Regularly (recommended every 250 working hours or monthly) visually inspect the outer skin of the wiring harness, especially the sections near metal edges, movable hinges (such as large and small arms), and high-temperature components (such as engines and exhaust pipes), to check for wear, breakage, aging cracks, or oil corrosion. If any problems are found, they should be promptly wrapped with specialized insulation tape or replaced with protective sleeves. Keep all connector plugs clean and dry, check if their locks are intact and if they are securely plugged in, to prevent poor contact, short circuits, or signal interruptions caused by looseness, oxidation, or oil contamination. When cleaning equipment, avoid direct flushing of wiring harnesses and connectors with high-pressure water guns.
