Mobilect 39

电气绝缘油

产品描述

mobilect™39是一种高质量的绝缘油与矿物不羁非常良好的介电性能和氧化稳定性，用于变压器，开关和其他电气设备。

39是mobilect不羁和符合标准IEC 60296（04）和ASTM d1275b / CIGRE腐蚀试验要求。

特点和优点

mobilect 39具有高的耐热和化学在铁和铜的存在下的降解，从而减少倾向产生污泥和油溶性氧化产物。当低质量的油被使用时，这些可能会形成在变压器的存款，并阻碍对流电流的干扰传热。此外，存款可能会加速绝缘缺陷，往往是非常困难的，没有完整的拆除拆除。

mobilect 39是专门处理以除去水分在制造。水将减少石油的电绝缘性能，促进氧化。是要记住，干油的吸湿性，吸收空气中的水分很重要。因此，它必须始终存放在干燥的条件和良好的封闭容器。强烈建议在使用前将产品干燥，或在采购后短时间内使用，以避免长期储存。

39的mobilect介电强度是电应力对油的抵抗程度是千伏在规定的试验条件下表达的差距。这不是一个衡量的石油质量，但没有污染物-特别是水分，纤维和极性化学品。

mobilect 39无蜡，即使在较低的温度，从而自由流通，在户外应用。它的粘度确保容易通过移动对流换热。流动性也是必不可少的开关设备中的电弧快速淬火。

低倒mobilect 39点保证在大多数情况下自由流动之间的变压器储油柜与保持在最低温度开关的可靠性。

应用

mobilect 39推荐使用的充油变压器和开关设备中的油应作绝缘介质或作为传热介质。

mobilect 39是用在应用程序指定的IEC 60296（04）一般规格和增强铜的腐蚀保护（通过ASTM d1275b腐蚀试验）。

mobilect 39不适用于充油电缆、特种浸渍过程中使用的电容器或。

Mobilect™ 39

Electrical insulating oils

Product Description

Mobilect™ 39 is a high quality mineral uninhibited insulating oil with very good dielectric properties and oxidation stability intended for transformers, switchgears and other electrical equipment.

Mobilect 39 is uninhibited and meets the specifications IEC 60296 (04) and ASTM D1275B / CIGRE corrosion tests requirements.

Features and Benefits

• Mobilect 39 has a high resistance to thermal and chemical degradation in the presence of iron and copper, which reduces tendencies to produce sludge and oil-soluble oxidation products. When lower quality oils are used these may form deposits in the transformer and impede heat transfer by interfering with convection currents. In addition deposits may accelerate insulation defects and are often very difficult to remove without complete dismantling.
• Mobilect 39 is specifically treated during manufacture to remove moisture. Water will reduce the electrical insulating properties of the oil and promote oxidation. It is important to remember that a dry oil is hygroscopic and absorbs moisture from the air. It must therefore always be stored in dry conditions and well-closed containers. It is strongly recommended to dry the product before use or use it within short notice after purchasing to avoid long term storage.
• The dielectric strength of Mobilect 39 is a measure of the resistance of the oil to electric stress and is expressed in kV across a specified gap under test conditions. This is not a measure of the quality of the oil but of the absence of contaminants - especially moisture, fibres and polar chemicals.
• Mobilect 39 is free from wax even at low temperatures and thus circulates freely in outdoor applications. Its viscosity ensures readily heat transfer by mobile convection currents. Mobility is also essential to quick quenching of arcs in switchgear units.
• The low pour point of Mobilect 39 ensures a free flow in most conditions between the transformer and the conservator and maintains the reliability of tap changers at the lowest temperatures. 

Applications

• Mobilect 39 is recommended for use in oil filled transformers and switchgears in which the oil is required as an insulation medium or as a heat transfer medium.
• Mobilect 39 is to be used in applications specifying IEC 60296 (04) General Specifications and reinforced copper corrosion protection (pass ASTM D1275B corrosion test).
• Mobilect 39 is not suitable for use in oil filled cables, for special impregnation processes or for use in capacitors.
