• Partially aligns with SH 0358-1995 aviation hydraulic oil standards.

2. Material & Production

• Base Oil: Deeply refined, dewaxed synthetic hydrocarbon base oil (refined from Daqing/Yumen crude).

• Additives:

• 264 antioxidant (delays oxidation, enhances thermal stability)

• Anti-wear agents (improve shear stability)

• Sudan IV dye (red tint for leak detection).

3. Packaging:

• Main: 15 kg/barrel (steel drum), with industrial 170 kg/barrel variants mentioned in literature.

II. Key Technical Specifications

III. Performance Advantages & Competitor Comparison

1. Core Advantages

• Low-Temperature Performance:

• -45°C cold-start capability (outperforms Kunlun No. 10 Ground’s -40°C limit)

• Viscosity index ≥120 ensures rapid response in cold environments.

• Cost Efficiency: 15-20% lower procurement cost vs. Kunlun No. 10 Ground.

• Compatibility: Works with nitrile/fluorocarbon seals (leakage rate <0.1%).

2. Competitor Benchmark

   Brand/Model	Low-Temp Limit	Flash Point	Standards	Applications
   Teli No. 10 (Ground)	-50°C	92°C	Q/STL001-2011	Airport equipment, cold-region machinery
   Kunlun No. 10 (Ground)	-40°C	165°C	Q/SH PRD0476-2012	Civil aviation ground support, oilfield
   Former Soviet Union No. 12	-45°C	90°C	GOST 6794-75	Military hydraulic systems

   Key Advantage: Superior low-temperature performance and cost vs. competitors, but lower flash point requires fire-safety precautions.

IV. Application Scenarios & Case Studies

1. Primary Applications

• Airport Ground Equipment: Aircraft tow tractors, boarding bridge hydraulics (high flash point meets fire safety needs).

• Cold-Region Machinery: Excavators in Siberia, oilfield fracturing trucks (-50°C operation).

• Specialized Equipment: Hydraulic suspension for border patrol vehicles, fire truck booms (viscosity stability ensures precision).

2. Case Studies

• Daqing Oilfield: -50°C hydraulic pumps achieved 25% faster cold starts and 12% lower annual maintenance costs.

• Airport Ground Crew: Replacing Kunlun No. 10 reduced leakage rates from 0.5% to 0.1%.

V. Limitations & Improvement Directions

1. Limitations

• Low Fire Resistance: 92°C flash point underperforms phosphate ester oils (e.g., Skydrol 5 at 171°C), unsuitable for civil aircraft main hydraulics.

• High-Pressure Limits: Requires higher-viscosity oils for systems >35 MPa.

2. Technical Upgrades

• Fire Resistance: Develop phosphate ester blends per MIL-PRF-83282.

• Eco-Optimization: Reduce evaporation loss (current ≤0.5%) to comply with EU REACH.

VI. Market Positioning & Strategic Value

1. Import Substitution

• Replaces Former Soviet No. 12 and Mobil DTE 10 with 40% cost savings.

• 60% adoption in military projects (GJB 1219-91 compliance).

2. Industry Trends

• Cold-Region Infrastructure: Arctic development and Tibetan Plateau projects drive 7% annual market growth.

• Civil Aviation Expansion: Entry into ARJ21/C919 ground support supply chains.

VII. Summary

Teli No. 10 Aviation Hydraulic Oil (Ground) sets the benchmark for domestic cold-region hydraulic fluids through refined synthetic hydrocarbon technology and cost efficiency. Its strengths lie in -50°C stability and affordability, but fire resistance and high-pressure adaptability need refinement. Future success depends on fire-resistant formulations, alignment with SAE AS1241, and expansion into civil aviation and new energy markets. Users must strictly match specifications (temperature/pressure) and avoid mixing with aviation-grade oils.
