Mobilect 39
電氣絕緣油
產(chǎn)品描述
mobilect?39是一種高質(zhì)量的絕緣油與礦物不羈非常良好的介電性能和氧化穩(wěn)定性，用于變壓器，開(kāi)關(guān)和其他電氣設(shè)備。
39是mobilect不羈和符合標(biāo)準(zhǔn)IEC 60296（04）和ASTM d1275b / CIGRE腐蝕試驗(yàn)要求。
特點(diǎn)和優(yōu)點(diǎn)
mobilect 39具有高的耐熱和化學(xué)在鐵和銅的存在下的降解，從而減少傾向產(chǎn)生污泥和油溶性氧化產(chǎn)物。當(dāng)?shù)唾|(zhì)量的油被使用時(shí)，這些可能會(huì)形成在變壓器的存款，并阻礙對(duì)流電流的干擾傳熱。此外，存款可能會(huì)加速絕緣缺陷，往往是非常困難的，沒(méi)有完整的拆除拆除。
mobilect 39是專門(mén)處理以除去水分在制造。水將減少石油的電絕緣性能，促進(jìn)氧化。是要記住，干油的吸濕性，吸收空氣中的水分很重要。因此，它必須始終存放在干燥的條件和良好的封閉容器。強(qiáng)烈建議在使用前將產(chǎn)品干燥，或在采購(gòu)后短時(shí)間內(nèi)使用，以避免長(zhǎng)期儲(chǔ)存。
39的mobilect介電強(qiáng)度是電應(yīng)力對(duì)油的抵抗程度是千伏在規(guī)定的試驗(yàn)條件下表達(dá)的差距。這不是一個(gè)衡量的石油質(zhì)量，但沒(méi)有污染物-特別是水分，纖維和極性化學(xué)品。
mobilect 39無(wú)蠟，即使在較低的溫度，從而自由流通，在戶外應(yīng)用。它的粘度確保容易通過(guò)移動(dòng)對(duì)流換熱。流動(dòng)性也是必不可少的開(kāi)關(guān)設(shè)備中的電弧快速淬火。
低倒mobilect 39點(diǎn)保證在大多數(shù)情況下自由流動(dòng)之間的變壓器儲(chǔ)油柜與保持在最低溫度開(kāi)關(guān)的可靠性。
應(yīng)用
mobilect 39推薦使用的充油變壓器和開(kāi)關(guān)設(shè)備中的油應(yīng)作絕緣介質(zhì)或作為傳熱介質(zhì)。
mobilect 39是用在應(yīng)用程序指定的IEC 60296（04）一般規(guī)格和增強(qiáng)銅的腐蝕保護(hù)（通過(guò)ASTM d1275b腐蝕試驗(yàn)）。
mobilect 39不適用于充油電纜、特種浸漬過(guò)程中使用的電容器或。
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.
