保护变压器免受腐蚀、污泥沉积和水解。
您是否注意到变压器内有凝结的水珠，甚至更严重的情况： 膨胀机生锈、储存介质中有游离水、油箱中有污泥沉积物以及变压器二极管滑动变脏？原因何在？在释放存储介质和吸入空气以平衡压力时，水分和污垢颗粒会畅通无阻地进入油箱。
面对现实吧，如果你不采取任何措施，就会面临昂贵的维修费用。
幸运的是，有一种解决方案：安装 GIEBEL Adsorber®。它可以干燥和清洁供气，防止污染物逃逸，为您节省维护工作和资金。

FAQ regarding transformers.
Malfunctions & troubleshooting
A loss in dielectric strength occurs when moisture enters the transformer through the breather during breathing cycles. Moisture reduces the insulation properties of the oil, promotes breakdown of solid insulation, and increases the risk of partial discharges and faults.
What you can do: Replace conventional breathers with a GIEBEL Adsorber® to eliminate moisture ingress and stabilize the dielectric strength of your transformer oil.
Why is my transformer forming internal condensation and how can I avoid it?
Condensation forms inside transformers when humid air is drawn in and temperature fluctuations cause the moisture to condense. This leads to corrosion of internal components and accelerates insulation degradation.
What you can do: Use a GIEBEL Adsorber® to prevent moisture from entering the transformer during pressure equalization and eliminate the root cause of condensation.
Sludge develops when moisture and oxygen cause oil oxidation, leading to acidic by-products that settle as sludge. This restricts oil flow, clogs filters, and reduces cooling efficiency.
What you can do: Prevent the entry of moisture and particles by installing a GIEBEL Adsorber® on your transformer breather to maintain oil quality and avoid sludge build-up.
Oil leaks can be caused by internal pressure build-up due to temperature expansion. Without proper ventilation, seals are overloaded, leading to oil seepage and leaks.
What you can do: Install a GIEBEL Adsorber® to enable safe pressure equalization while preventing dirt and moisture ingress, reducing seal stress and leaks.
Transformer oil & filtration
Transformer oil can last for many years, but moisture and contamination accelerate degradation. Using a GIEBEL Adsorber® prevents moisture ingress, extending oil service life and reducing the need for premature oil changes.
What you can do: Equip your transformer with a GIEBEL Adsorber® to keep oil in optimal condition and extend replacement intervals.
Signs of contamination include a reduction in dielectric strength, higher moisture ppm levels, darkening of the oil, sludge formation, and gas-in-oil detection issues.
What you can do: Prevent contamination from developing by eliminating external moisture sources with a GIEBEL Adsorber® on your transformer breather.
Contaminated oil leads to accelerated insulation aging, higher operating temperatures, increased partial discharge activity, and a higher risk of catastrophic failure.
What you can do: Install a GIEBEL Adsorber® to maintain clean, dry oil and significantly extend transformer service life and reliability.
Efficiency & optimization
By maintaining clean, dry oil and eliminating moisture ingress, you reduce breakdown risks, minimize maintenance interventions, and avoid costly outages.
What you can do: Install a GIEBEL Adsorber® to maintain consistently optimal conditions inside your transformer and reduce risk of failures.
Moisture is a key driver of oil degradation and insulation damage, both of which result in increased maintenance needs. Blocking moisture ingress reduces oil testing frequency, delays refurbishments, and lowers total lifecycle costs.
What you can do: Use a GIEBEL Adsorber® to minimize oil aging, extend component life, and reduce unplanned maintenance costs.
Service & parts
GIEBEL offers adsorbers sized according to oil volume, load cycles, and environmental conditions. Specialized options are available for outdoor use, high-humidity environments, and ATEX zones.
What you can do: Contact GIEBEL or use the product selector to choose the correct adsorber tailored to your transformer setup.
GIEBEL Adsorbers® are designed for easy retrofitting on standard transformer breathers. They can be mounted directly on the breather connection point without the need for complicated modifications.
What you can do: Follow GIEBEL’s straightforward mounting guide to quickly secure your transformer with reliable moisture protection.
All GIEBEL Adsorbers® use color-indicating silica gel that visibly shows saturation. When the gel changes color completely, it signals the need to refill or replace the drying agent.
What you can do: Monitor the color status of your adsorber and perform timely maintenance to guarantee continuous protection.
