insulative transformer oil

insulative transformer oil
1. Blended with highly refined mineral base oil and well-chosen anti-oxidizer.
2. Excellent quality
insulative transformer oil

1.Features:
Insulative transformer Oil is blended with highly refined mineral base oil and well-chosen anti-oxidizer, suitable for insulation and cooling for transformer, oil immersed switch and other insulation device of electrical appliances.
Outstanding electrical insulation performance, effectively preventing occurrence of discharge in electric field.
Good oxidation stability, effectively preventing formation of acidic material and sludge.
Good thermal conductivity, ensuring effective cooling of transformer core and coiling.
2. Application:
As insulating and cooling medium for transformer of 330kV or below as well as electrical appliance with similar requirements.

3. Product Standard:
Meets IEC 60296, GB2563-90

4. Note:
(1). Avoid refueling and renewing oils to the equipments in wet. (2). Dry and filter the oil before using in the equipment and make sure the breakdown voltage is qualified. (3). The upper oil temperture should be under 85°C to prevent the oil temperture from overtopping. (4). Use nitrogen filled protection or thermo-siphon filter to reduce the contact between oil and air,or remove tidal air and oxide that caused by the respiration of transformer.
(5). Doing the regular sampling analysis to check out the changes of oilness and the consumption of antioxgen. Filter and add the antioxygen when neccessary.
