803103961 XCMG GR2605 motor grader plug

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 ≥12mm, an effective explosion-proof joint surface length ≥28mm, and a gap ≤0.5mm, meeting Ex dIMb explosion-proof standards. This effectively 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 powder coating, and is filled with a flame-retardant and anti-static material. Its surface resistance is ≤1×10^8Ω, and it boasts an IP67 high protection rating, resisting dust intrusion, immersion in 1m of water, and high-pressure water washing. It is suitable for a wide operating temperature range of -40℃ to 120℃ (insulation performance remains undiminished at high temperatures and does not become brittle at low temperatures), with a service life of over 9 years under harsh outdoor conditions. It employs a 5-core hyperboloid spring-loaded socket design with a contact diameter of 2.4mm and a rated current of 20A. Compared to traditional pinhole structures, the contact area is increased by 40%, with a contact resistance ≤1.5mΩ and signal transmission attenuation ≤0.2%. Combined with oil-resistant and aging-resistant silicone rubber seals (Shore hardness 60-70, compression set ≤15%), it can withstand over 8000 insertion/removal cycles without loosening, ensuring zero-delay and uninterrupted power and signal transmission. The interface specifications strictly match the original installation dimensions of XCMG GR2605, supporting quick adaptation of mining flame-retardant cables with an outer diameter of 6-14mm (compliant with MT/T 818 standard). It adopts a bayonet-type quick connection structure, which does not require special tools during installation. It can be locked by rotating 30°. Disassembly is convenient 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, and vibration. As a “safe and quick connection hub” for the entire machine’s electrical system, its explosion-proof and high-protection design can stably connect the power and signal transmission of key components such as sensor circuits, hydraulic control modules, braking system electrical components, lighting equipment, and communication terminals, effectively avoiding electrical faults or safety accidents caused by loose connections, insulation failure, or insufficient explosion-proof performance. At the same time, it adopts a bayonet-type quick connection structure, supporting quick plugging and unplugging and on-site maintenance. Combined with the high reliability design of the hyperboloid spring-loaded socket, it significantly improves the continuity of operation and operational safety of the entire machine. It is an original factory-grade precision-matched part for the maintenance and replacement of the XCMG GR2605 grader’s electrical system, fully meeting the high safety, high reliability, and convenient maintenance requirements of mining operations.
