Cycloalkane Based Transformer Oil I-40
Transformer oil exhibits excellent thermal stability, effectively mitigating the rise in internal temperature during prolonged equipment operation, thereby sustaining equipment's operational efficiency. Over long operating hours, electrical equipment generates considerable internal heat. Transformer oil, functioning as a coolant, circulates to dissipate this heat through the radiator, ensuring equipment's continued smooth operation.
Product Details：Cycloalkane Based Transformer Oil I-40
The product's insulating properties are exceptional, boasting a dielectric strength that far exceeds air. The oil immersion of the insulating material not only enhances its insulating capabilities but also shields it from the damaging influence of moisture. Transformer oil is thus instrumental in preventing short-circuit malfunctions and maintaining the smooth operation of electrical devices.

1. Essential Functions of Transformer Oil
(1) Integral to Transformers: Transformer oil serves as a cornerstone in transformers, offering insulation and cooling mechanisms for essential parts, namely windings and cores.
(2) Electrical Safety Enhancement: It proficiently establishes electrical barriers, mitigating risks of electric arcs and shocks, while also facilitating effective heat dissipation to maintain transformer stability.
(3) Widespread Application in Electrical Infrastructure: Apart from transformers, this oil is instrumental in insulating and cooling a myriad of electrical devices, including cables, switchgear assemblies, reactors, and circuit breakers.
(4) Power Electronics' Essential Fluid: In power electronics systems, particularly inverters and capacitors, transformer oil plays a vital role in insulation and thermal management.
(5) Vital for Systemic Maintenance: Transformer oil is indispensable in the upkeep of power systems, aiding in the purification of equipment and early detection of potential failures through meticulous chemical and physical assessments.
2. Characteristics
(1) Cooling performance
Transformer oil has good heat conduction performance, can effectively absorb and disseminate the heat generated inside the transformer, to maintain the normal working temperature of the transformer.
(2) Anti-oxidation performance
Transformer oil can resist oxidation reaction, prolong service life, reduce oil deterioration and corrosion.
(3) Low volatility
Transformer oil has low volatility, which can reduce oil loss and replenishment frequency during long time use.
