C0Bk transformers

Quality and the highest level of energy efficiency in full compliance with EU standards and national regulations.

As of July 1, 2021, Energomont implements Commission Regulation (EU) 2019/1783 (Tier 2), which aims to increase energy efficiency and reduce CO₂ emissions in power transformers. Our oil-filled TIER2 transformers are fully compliant with these requirements, providing reliable and environmentally sustainable solutions.

All our products conform to the European Directive EN 50464-1 and undergo testing in accordance with the European Directive EN (IEC) 60076. We strictly adhere to all specified European directives, and each transformer undergoes routine testing to confirm quality. Additionally, we conduct type tests and hold certificates from independent laboratories for all our products.

Key Advantages of C0Bk Transformers:
  • Reduced energy losses – Direct savings in electricity consumption
  • Competitive pricing – Cost-effective solution with high performance
  • Optimal price-to-quality ratio – Best value for investment
  • Long-term reliability – Stable operation
  • Stable operation – Lower operational costs throughout the lifecycle

Available Versions of C0Bk Transformers

C0Bk TRANSFORMERS
– HERMETICALLY SEALED

  • Fully sealed system – Hermetically enclosed transformers require minimal maintenance as they are completely isolated from air exposure.

  • Perfect for indoor installation – Compact and leak-proof design with zero risk of oil spills.

  • Available in booth copper and aluminium versions

C0Bk TRANSFORMERS
-WITH CONSERVATOR

  • Designed for reliable operation in harsh conditions

  • Easier monitoring and maintenance

  • Extended transformer lifespan capability

  • Available in copper and aluminium versions

Efficiency class – C0Bk

For a more efficient and cost-effective power system, we recommend low-loss C0Bk category transformers.
These transformers offer the optimal price-to-quality ratio – enabling significant electricity savings through reduced losses, with relatively low investment.
Thanks to their carefully engineered design and use of high-quality materials, C0Bk transformers ensure long-term reliability and stable operation in all conditions.

Every ENERGOMONT power transformer comes equipped with a set of high-quality components that guarantee long-term reliability.

Standardni opremljenost transformatora:

  • High-voltage terminal (HV terminal) – Available in standard ceramic design or Plug-in type

  • Low-voltage terminal (LV terminal) – With or without flag-type connectors (OSa)

  • Relay protection – Detects oil level changes or gas accumulation (Buchholz relay)

  • Identification plate – Centralized technical data for easy reference

  • Wheels – Ensures mobility even for heavy models

  • Pressure relief valve – Prevents tank damage during faults (for hermetically sealed transformer)

Primary purpose of C0Bk transformers:
  • Power distribution systems – for maximum efficiency in long-term operation

  • Industrial plants with critical loads – where reliability and savings are a priority

  • Energy-intensive facilities – where high efficiency directly impacts operating costs
