803174824 XCMG GR2605 motor grader connector

Core Product Advantages

Specifically designed for the XCMG GR2605 motor grader, this product perfectly matches the model’s 194kW rated power output and heavy-duty electrical system load requirements. It is precisely suited for harsh operating environments such as mining, open-pit mining, and large-scale infrastructure construction, characterized by dust, humidity, severe vibration, and flammable and explosive conditions. The casing is made of Q235A steel plate with CO2 gas shielded welding, with a wall thickness ≥15mm, an effective explosion-proof joint length ≥30mm, and a gap ≤0.4mm, meeting Ex dIMb explosion-proof standards. This completely blocks the propagation of explosion flames and eliminates the risk of gas and coal dust explosions caused by electrical sparks. The casing surface undergoes multi-layer anti-corrosion and wear-resistant treatment, and the interior is filled with a flame-retardant and anti-static material with a surface resistance ≤1×10^8Ω. It also boasts an IP68 high protection rating, resisting dust intrusion, long-term immersion in 1.5m water, and high-pressure water washing. It is suitable for a wide temperature range of -40℃ to 85℃ and has a service life of over 10 years under harsh outdoor conditions. Featuring a 7-pin + hole hybrid contact design, it supports synchronous transmission of power, audio, control commands, and CAN bus data. Equipped with oil-resistant and aging-resistant fluororubber seals (Shore hardness 65-75, compression set ≤18%), it can withstand over 5000 mating cycles without loosening, with contact resistance ≤0.01Ω and signal transmission attenuation ≤0.3%, ensuring zero-delay and uninterrupted power and signal transmission. The interface specifications strictly match the original XCMG GR2605 installation dimensions, supporting rapid adaptation of 8-16mm outer diameter mining flame-retardant cables. Direct replacement is possible without additional modifications, and installation only requires tightening to the specified torque of 8-12 N·m, significantly reducing maintenance costs and downtime losses, fully meeting XCMG’s high reliability and mining safety standards.
