803106731 XCMG GR2605 motor grader connector

Core Product Advantages

Specifically designed for the XCMG GR2605 motor grader, this connector 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, large-scale infrastructure construction, and underground auxiliary operations, characterized by dust, humidity, severe vibration, flammability, explosiveness, and complex conditions. The high-strength cast aluminum alloy unibody shell has a wall thickness ≥16mm, an effective explosion-proof mating surface length ≥38mm, and a gap ≤0.3mm, meeting Ex dIMb explosion-proof standards. This completely blocks the propagation of explosion flames, eliminating the risk of gas and coal dust explosions caused by electrical sparks. Its explosion-proof performance is 30% higher than ordinary mining connectors. The outer shell undergoes double anti-corrosion treatment with anodizing and ceramic composite coating, with a salt spray corrosion resistance of over 1200 hours. The interior is filled with flame-retardant and anti-static special material with a surface resistance of ≤1×10^8Ω. It also has an ultra-high protection rating of IP68++, which can withstand dust intrusion, long-term immersion in 5m water, and 100bar high-pressure water washing. It is suitable for wide temperature working environment from -40℃ to 135℃ (insulation performance at high temperature decreases by ≤3%, and bending at low temperature of -40℃ without brittleness). Under harsh outdoor conditions, it has a service life of over 15 years. Featuring a 12-pin gold-plated alloy contact design with a contact diameter of 3.2mm, a rated current of 35A, and a gold plating thickness ≥0.8μm, this device incorporates antioxidant alloy components, resulting in 100% improved wear resistance and corrosion resistance compared to traditional gold-plated structures. Contact resistance is ≤0.5mΩ, and signal transmission attenuation is ≤0.05%. Equipped with oil-resistant and aging-resistant perfluoroether rubber seals (Shore hardness 75-85, compression set ≤8%), it can withstand over 15,000 insertion/removal cycles without loosening, ensuring zero-delay and uninterrupted synchronous transmission of power, multiple control signals, data, and emergency circuits. The interface specifications strictly match the original installation dimensions of XCMG GR2605, supporting rapid adaptation of mining flame-retardant shielded cables with an outer diameter of 12-22mm (compliant with MT/T 818 standard). It adopts a double fixing structure of threaded locking + anti-loosening washers, with an installation torque of 15-20N・m, which can resist the risk of loosening caused by high-frequency vibration (5-3000Hz) and impact load. It is easy to disassemble and replace old parts directly without additional modification, which greatly reduces maintenance costs and downtime losses, and fully meets the high reliability and mining safety standards of XCMG parts.
