803103852 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 high-strength cast aluminum alloy unibody shell has a wall thickness ≥14mm, an effective explosion-proof joint surface length ≥32mm, 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 outer shell undergoes a double anti-corrosion treatment of anodizing and wear-resistant powder coating. 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 2m of water, and high-pressure water washing. It is suitable for a wide operating temperature range of -40℃ to 125℃ (insulation performance remains undiminished at high temperatures and does not become brittle at low temperatures), with a service life of over 10 years under harsh outdoor conditions. It employs an 8-core gold-plated contact design with a contact diameter of 2.8mm, a rated current of 25A, and a gold plating thickness ≥0.5μm. Compared to traditional silver-plated structures, its oxidation resistance is improved by 60%, contact resistance ≤1mΩ, and signal transmission attenuation ≤0.1%. Combined with oil-resistant and aging-resistant fluororubber seals (Shore hardness 65-75, compression set ≤12%), it can withstand over 10,000 insertion/removal cycles without loosening, ensuring zero-delay and uninterrupted power supply and multi-type signal transmission. The interface specifications strictly match the original installation dimensions of XCMG GR2605, supporting rapid adaptation of mining flame-retardant cables with an outer diameter of 8-18mm (compliant with MT/T 818 standard). It adopts a threaded locking anti-loosening structure with an anti-detachment pin design, and the installation torque is 10-15N・m. It can resist the risk of loosening caused by high-frequency vibration. It is easy to disassemble and can be directly replaced without additional modification, which greatly reduces maintenance costs and downtime losses. It fully meets the high reliability and mining safety standards of XCMG accessories.

Application scenarios

Suitable for electrical system connection conditions of XCMG GR2605 graders in mining, open-pit mining operations, highway construction, and large-scale infrastructure projects, especially suitable for harsh mining environments with high gas, high dust, humidity, vibration, and high-frequency start-stop. As the “safety integrated connection hub” of the entire machine’s electrical system, its explosion-proof and high-protection design can stably connect key components such as drive system electrical components, hydraulic control modules, multi-channel sensor networks, braking system electrical components, lighting equipment, and communication terminals. This enables integrated transmission of power, control commands, and data signals, effectively preventing electrical faults or safety accidents caused by loose connections, insulation failure, or insufficient explosion-proof performance. Simultaneously, its high-reliability design, featuring a threaded locking anti-loosening structure and gold-plated contacts, supports quick plugging and unplugging and on-site maintenance, significantly improving the continuity of operation and operational safety. It is an original equipment manufacturer (OEM) precision-fit part for the XCMG GR2605 grader’s electrical system repair and replacement, fully meeting the high safety, high reliability, and strong vibration resistance requirements of mining operations.
