Frequently Asked Questions
Why choose Schneider Trihal over oil-immersed transformers?
Trihal is oil-free, eliminating fire and leakage risks, making it ideal for indoor infrastructure like hospitals and data centers.
What is the benefit of the F1 fire rating?
It guarantees the transformer is self-extinguishing and produces no toxic gases during a fire, ensuring maximum safety for high-occupancy buildings.
Does the Trihal transformer require regular maintenance?
No. Its cast resin design is virtually maintenance-free, only requiring occasional cleaning of the cooling air channels.
Can it handle extreme cold or thermal shocks?
Yes, with its C2 climatic rating, it can operate in temperatures as low as -25°C and handle sudden, heavy load changes.
Is it suitable for humid or polluted environments?
Yes, the E2 rating ensures reliable performance in environments with high humidity or heavy pollution without track-mark risks.
What cooling methods are available?
We offer Natural Air (AN) as standard and Forced Air (AF) to increase power capacity by up to 40% when needed.
