803164370 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 electrical system voltage and current requirements. It is precisely suited for harsh operating environments such as mining, construction, and open-pit mining, characterized by dust, humidity, severe vibration, and flammable and explosive conditions. The high-strength cast steel unibody shell has a wall thickness ≥12mm, an effective explosion-proof joint length ≥25mm, and a gap ≤0.5mm, 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 shell surface undergoes multi-layer anti-corrosion treatment, and the interior is filled with flame-retardant and anti-static material with a surface resistance ≤1×10^8Ω. It also boasts an IP68 high protection rating, resisting dust intrusion, mud and water immersion, and high-pressure water washing. It is suitable for a wide temperature range of -40℃ to 85℃ and has a service life of over 8 years under harsh outdoor conditions. Employing a dual-fixing structure of snap-fit ​​and threaded locking, coupled with oil-resistant and aging-resistant fluororubber seals (Shore hardness 60-80, compression set ≤20%), it can withstand over 1000 insertion/removal cycles without loosening, with contact resistance ≤0.01Ω and signal transmission attenuation ≤0.5%, ensuring zero delay and uninterrupted power and signal transmission. The interface specifications strictly match the original XCMG GR2605 installation dimensions, supporting quick adaptation for cables with outer diameters of 6-12mm. Direct replacement is possible without additional modifications; installation only requires tightening to the specified torque, significantly reducing maintenance costs and downtime losses, fully meeting XCMG’s high reliability and mining safety standards.
