803103351 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, 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 ≥15mm, an effective explosion-proof mating surface length ≥35mm, and a gap ≤0.35mm, 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 20% higher than ordinary mining connectors. The outer shell undergoes double anti-corrosion treatment with anodizing and ceramic coating, and its salt spray corrosion resistance exceeds 1000 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 IP68+ high protection rating, which can withstand dust intrusion, long-term immersion in 3m water, and 80bar high-pressure water washing. It is suitable for wide temperature working environment from -40℃ to 130℃ (insulation performance at high temperature decreases by ≤5%, and there is no brittle cracking when bent at low temperature of -40℃). Its service life is more than 12 years under harsh outdoor conditions. It adopts a 10-core rhodium-plated contact design with a contact diameter of 3.0mm, a rated current of 30A, and a rhodium plating thickness of ≥0.3μm. Compared with the traditional gold-plated structure, the wear resistance and oxidation resistance are improved by 80%, the contact resistance is ≤0.8mΩ, and the signal transmission attenuation is ≤0.08%. It is equipped with oil-resistant and aging-resistant perfluororubber seals (Shore hardness 70-80, compression set ≤10%), and can withstand more than 12,000 insertion and removal cycles without loosening. It ensures zero delay and uninterrupted synchronous transmission of power and multiple signals (control commands, data, audio). The interface specifications strictly match the original installation dimensions of XCMG GR2605, supporting rapid adaptation of mining flame-retardant cables (compliant with MT/T 818 standard) with an outer diameter of 10-20mm. It employs a dual fixing structure of threaded locking and anti-loosening nuts, with an installation torque of 12-18 N·m, resisting the risk of loosening caused by high-frequency vibration (10-2000Hz). Disassembly is convenient, allowing direct replacement of old parts without additional modifications, significantly reducing maintenance costs and downtime losses, fully meeting XCMG’s high reliability and mining safety standards.

Application scenarios

Suitable for XCMG The GR2605 grader is suitable for electrical system integration and connection in scenarios such as mining, open-pit mining, highway construction, and large-scale infrastructure projects. It is especially well-suited for the harsh mining environment characterized by high gas content, high dust levels, humidity and vibration, high-frequency start-stop, and dense signal transmission. As the “safety integration and connection hub” of the entire machine’s electrical system, its reinforced explosion-proof and ultra-high voltage 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, navigation terminals, and communication modules. This enables integrated synchronous transmission of power supply, multi-channel control commands, and data signals, effectively preventing electrical faults and safety accidents caused by loose connections, insulation failure, insufficient explosion-proof performance, or signal interference. Simultaneously, its high-reliability design, featuring a double anti-loosening structure and rhodium-plated contacts, supports quick plug-and-play and on-site maintenance, significantly improving the continuity of operation and operational safety. It is an original equipment manufacturer (OEM) precision-fit accessory for the XCMG GR2605 grader’s electrical system repair and replacement, fully meeting the high safety, high reliability, strong vibration resistance, and multi-signal integration requirements of mining operations.
