Scientific wiring optimization: Categorize transmission to avoid signal interference.

The electrical equipment in the rear frame area is complex, with power cables and signal cables intertwined, making it prone to electromagnetic interference. LiuGong. 08C8154 The rear frame wiring harness uses “ Categorized cabling + Shielding isolation ” Optimized design: Arrange high-voltage power lines (such as hydraulic pump power supply lines) and low-voltage signal lines (such as sensor feedback lines) in separate groups, maintaining a spacing of... 10cm The above-mentioned components are separated by flame-retardant partitions; key signal lines, such as brake signals and hydraulic control lines, employ a double-layer shielding structure. —— The inner aluminum foil shield isolates high-frequency interference, while the outer tinned copper wire braid enhances anti-interference capability, ensuring that signal transmission errors are kept within... 0.1% Within this range, avoid issues such as delayed brake response and sluggish hydraulic actuation; the harness bends should be designed with... “ Large-radius transition ” Design: The bending radius shall not be less than the diameter of the conductor. 10 Additionally, it prevents cracking of the wire insulation layer and leaves ample operational space for future maintenance, significantly enhancing ease of maintenance.

Upgraded robust material: durable and damage-resistant, suitable for harsh working conditions.

To address the harsh operating environment of the rear frame wiring harness, LiuGong has implemented triple reinforcement in terms of materials: the wires feature multi-strand, high-purity oxygen-free copper cores, which offer significantly improved conductivity compared to conventional copper cores. 15% It boasts superior flexibility and can withstand millions of bends without cracking, even under the vibrations caused by equipment. The insulation layer is made from materials that are oil-resistant and weather-resistant. XLPE Material, in -40℃ To 130℃ Maintains stable insulation performance within the specified temperature range and does not age or harden even after prolonged contact with hydraulic oil and mud/water; the connector housing is made of high-strength material.

UL94 V-0 Class-level flame-retardant standards reduce the risk of short-circuit fires; rubber wear-resistant sleeves are installed at the points where wiring harnesses pass through metal openings in the vehicle frame to prevent metal edges from cutting through the insulation layer; connector interfaces adopt... IP67 The design features waterproofing with a built-in, age-resistant silicone sealing ring. Even under heavy rain or muddy working conditions, it effectively prevents water and dust from entering, ensuring that the connectors remain dry and clean. The grounding terminals at the end of the wire harness are galvanized and secured with anti-loosening nuts, which help prevent static buildup and signal interference caused by poor grounding. Field tests have shown that this wire harness boasts a significantly longer service life in muddy mine environments compared to conventional harnesses. 50% The above.

End-to-end quality control assurance: Original manufacturer standards, ensuring impeccable quality.

LiuGong vs. 08C8154 The rear frame wiring harness implements comprehensive quality control across the entire supply chain—from raw materials to finished products: Raw materials such as copper cores and insulating layers must pass tests for electrical conductivity, temperature resistance, and oil resistance; connectors must undergo verification of their mating durability (reaching...). 1000 (At least once); during the production process, each batch of wire harnesses must undergo continuity testing (to ensure there are no loose connections or broken wires) and insulation resistance testing (with insulation resistance greater than...). 200 MΩ )、anti-interference testing (simulating operational conditions to verify signal stability); during the finished-product stage, vibration testing is also required (simulating equipment jolting). 48 No failures within one hour), high- and low-temperature cycling test ( -40℃ To 130℃ Cycle 50 Next performance is stable) and waterproof testing (immersion) 1 Rice water depth 30 No leakage detected within the specified time frame.
