Structural features

- High-quality wire materials are used, which have good conductivity, insulation and high temperature resistance, and can adapt to the harsh environment in the engine compartment.

- The wiring harness is connected to various engine components through multiple plugs and sockets. The plugs and sockets are precisely designed to ensure a firm connection and prevent poor contact.

- To protect the wiring harness from wear and corrosion, the outside is wrapped with an insulating layer and a protective cover. Some wiring harnesses also use a braided net or corrugated tube for additional protection.

- Wire harness aging: After long-term use, the insulation layer of the wire harness will age and crack, causing the wires to be exposed, which can easily cause short circuits or open circuit faults.

- Loose plugs or poor contact: The vibration of the excavator during operation may cause the plug to loosen, resulting in unstable signal transmission and abnormal engine operation, such as jitter, lack of power, etc.

- Damaged wire harness: Sharp parts or high-temperature parts in the engine compartment may wear or burn the wire harness, causing line damage.
