We offer a comprehensive range of insulating oil related products and work in partnership with our clients to share our knowledge and expertise on what works best.
EOS® Premium Regenerated Transformer Oil
EOS® Premium is a regenerated insulating oil meeting the requirements of IEC60296:2020 – “Mineral insulating oils for electrical equipment”.
Unused Uninhibited Mineral Insulating Oil
EOS stores around 2 million litres of unused uninhibited mineral insulating oil, meeting the modern and exacting standard IEC 60296:2020, NGTS 3.3.1 and most other national and international standards.
Unused Inhibited Mineral Insulating Oil
EOS stores around 2 million litres of unused inhibited mineral insulating oil meeting, the modern and exacting standard IEC 60296:2020, NGTS 3.3.1 and most other national and international standards.
Reclaimed Uninhibited Insulating Oil
Electrical Oil Services Ltd (EOS) and its ancestor companies have been producing Regenerated Insulating Oil to BS148 for more than 60 years. This provides the UK electricity supply industry, and large industrial energy users, with a sustainable alternative to resource depletion caused by the consumption of unused oil from refiners. In doing so many millions of litres of used insulating oil have been kept within the “recycling loop” and not lost to burning or other single use applications.
Insulating oil passivator concentrate is supplied in bulk (by road tanker), 205 litre steel drums or 25 litre containers.
Insulating oil inhibitor concentrate is supplied in bulk (by road tanker), 205 litre steel drums or 25 litre plastic containers.
EOS Silicone Transformer Liquid is a polydimethyl silicone liquid that is suitable for transformers and other electrical equipment designed to operate at high temperatures or at very low temperatures.
Midel Synthetic Ester
Midel is the world’s leading brand of ester-based dielectric fluids and is chosen by utilities and transformer manufacturers worldwide because of its excellent track record and ability to minimise risk.
205L Drum Cover
The EOS 205L drum cover is a tight fitting lid that prevents rain and debris from settling on the top of the drum.
Acidity Testing Solution
The EOS acidity testing solution is produced to enable a simple estimation of the acidity of insulating oils to be carried out in the field.
This purpose-designed tool removes tab-seals and 2″ and ¾” bungs from drums.
Glass Sampling Thief
The EOS glass sampling thief is used for taking a representative sample of oil from the bottom of a 205 litre steel drum, a 25 litre plastic container or oil filled switchgear.
Transformer Oil Sampling Toolkit
The EOS Transformer Oil Sampling Kit is designed to help you obtain a transformer oil sample from transformer bottom valves with threads up to 2” BSP.d.
Switch Contact Compound
Switch Contact Compound is a smooth textured electrical contact grease used for sliding and simple static contacts to improve conductivity and separation during operation.
The Art of Transformer Oil Sampling Training DVD – EOS has a professionally produced, 25-minute, general electrical oils training video. It contains much useful advice and information on insulating oil storage, handling, sampling and testing.
Lint Free Wipes
Lint free wipes are fibre free, non-hygroscopic polypropylene cloths, ideal for wiping, oil handling, sampling and laboratory equipment.
Used transformer oil labels are free issue to customers wishing to return their used transformer and switchgear oil to EOS.
EOS crackle test tubes can be used to perform a crackle test.
Bunded pallets are used for storing drums on site where spillage is a concern. EOS bunded pallets are available for hire for a small charge.
New 25 Litre Plastic Containers
New 25L plastic containers can be used for the return of used Insulating oil to EOS for reclamation, or where customers are decanting from a larger bulk storage point for ease of use at site.
New 205L Steel Drums
New 205L steel drums are used for the temporary storage (i.e. less than 1 day) of small quantities of insulating oil that has been removed from transformers or switchgear to facilitate servicing.
Reconditioned 205L Drums
Reconditioned drums are used for the return of used insulating oil for reclamation (or, where necessary, disposal).
Guaranteed structurally sound reconditioned drums are NOT covered by the EOS Quality Control system and therefore should not be used for temporary storage of insulating oil – e.g. to facilitate maintenance activities.
