Introduction

Non Conductive Hydraulic Oil ISO 22 Shell Chevron represents a vital category of lubricants specially engineered for environments where electrical conductivity must be minimized or eliminated. These oils are commonly used in areas near high-voltage equipment, ensuring both operational safety and performance. With increasing attention on electrical safety in industrial and utility applications, demand for high-grade non conductive hydraulic oils has surged.

This article delves into the fundamentals of non conductive hydraulic oil, particularly those adhering to ISO 22 viscosity standards, and highlights two globally recognized brands—Shell and Chevron. Whether you’re an engineer, a maintenance supervisor, or a procurement specialist, understanding these oils' properties and applications is essential in choosing the right product for your operations.

Non Conductive Hydraulic Oil

Non Conductive Hydraulic Oil is a specially formulated type of lubricant designed with extremely high dielectric strength. Its primary purpose is to act as a hydraulic fluid while also preventing the conduction of electricity. These oils are particularly crucial in environments like power utilities, underground mining, and high-voltage industrial applications where electrical insulation is paramount.

Standard hydraulic oils, while effective for mechanical operations, may pose risks in electrically sensitive areas due to their potential to conduct electricity. Non conductive hydraulic oils reduce this risk by maintaining very low electrical conductivity levels, generally measured in picoSiemens per meter (pS/m). Most formulations also offer superior thermal stability, oxidation resistance, and anti-wear properties.

Non conductive oils also serve a dual function—power transmission and electrical insulation. They are widely used in equipment like aerial lifts (bucket trucks), electric forklifts, circuit breaker systems, and transformer maintenance vehicles. They ensure uninterrupted mechanical function while safeguarding workers and sensitive equipment from electrical hazards.

ISO 22 Non Conductive Hydraulic Oil

ISO 22 Non Conductive Hydraulic Oil refers to a non conductive fluid that meets the ISO VG 22 viscosity classification. This standard indicates a kinematic viscosity of 22 centistokes at 40°C, making it suitable for systems that require a light, fast-flowing fluid. ISO 22 hydraulic oils are typically used in cold environments or machinery with tight tolerances that necessitate low-viscosity fluids.

In the realm of non conductive oils, ISO 22 offers a balanced profile—low enough in viscosity for easy pumpability and rapid system circulation, yet sufficiently robust to offer lubrication and protection. No matter the viscosity grade, the oil retains its non conductive characteristics, ensuring reliable electrical insulation.

Industries that benefit from ISO 22 non conductive hydraulic oil include utility maintenance (especially for equipment operating near live power lines), aviation ground support, rail transport systems, and even wind turbine maintenance platforms. The oil's light viscosity minimizes startup torque, reduces energy consumption, and enhances overall system responsiveness—an important consideration for hydraulics operating in dynamic environments.

Shell Non Conductive Hydraulic Oil

Shell Non Conductive Hydraulic Oil is known for its precision formulation, premium base stocks, and advanced additive technology. Shell offers dielectric hydraulic fluids under its Tellus and Diala brands, which are engineered to meet stringent insulation standards while delivering exceptional wear protection and thermal stability.

Shell’s non conductive products often comply with global performance specifications, including ASTM D877 dielectric strength and ISO VG viscosity grades like ISO 22. These products are tested to withstand high voltages without electrical breakdown, making them ideal for aerial devices, utility bucket trucks, and insulated lift platforms.

Another critical benefit of Shell's formulations is their environmental consciousness. Many variants meet biodegradability standards and are labeled as environmentally acceptable lubricants (EALs), which is increasingly important for companies adhering to environmental compliance and sustainability goals.

By offering excellent resistance to oxidation over time, Shell products cut maintenance frequency and operational disruptions, making them a smart choice for long-duty or inaccessible machinery.

Chevron Non Conductive Hydraulic Oil

Chevron Non Conductive Hydraulic Oil offers a trusted solution for operators demanding both electrical safety and system reliability. Chevron's dielectric hydraulic oils, such as Chevron Rando HDZ or other specialized EHC (Electro-Hydraulic Control) fluids, are designed to meet or exceed industry standards for insulating performance.

Chevron oils typically boast a high dielectric breakdown voltage, often greater than 35 kV, which ensures superior protection in high-voltage environments. These oils are blended with premium Group II or Group III base stocks and are fortified with advanced antioxidant, anti-foam, and anti-wear additives.

For ISO 22 applications, Chevron's non conductive hydraulic oils provide stable viscosity characteristics across a broad temperature range. This thermal and oxidative stability helps reduce varnish formation, improves energy efficiency, and extends equipment life.

Chevron also emphasizes product compatibility and system cleanliness. Their oils are engineered to minimize the risk of sludge and deposits, which is vital for sensitive hydraulic systems. As a result, operators benefit from improved pump performance, reduced maintenance intervals, and enhanced equipment reliability—particularly crucial in critical applications like electrical substations and service vehicles.

Conclusion

Non Conductive Hydraulic Oil ISO 22 Shell Chevron serves as a crucial component in modern hydraulic systems operating near electrical hazards. These oils are specifically developed to prevent electricity conduction, protect workers, and preserve equipment functionality under high-voltage conditions. ISO 22 variants provide optimal flow and system responsiveness, especially in cold or tightly-toleranced environments.

Shell and Chevron, as industry leaders, offer high-performing, reliable non conductive hydraulic oils that meet global standards. Shell emphasizes premium additive chemistry and environmental responsibility, while Chevron focuses on performance, system protection, and extended service life.

In choosing a non conductive hydraulic oil, consider factors such as dielectric strength, viscosity grade, oxidation stability, and brand reliability. Whether for aerial lifts, electric vehicles, or sensitive industrial systems, selecting the right non conductive hydraulic oil can improve safety, reduce costs, and increase operational efficiency.
