4. 2. Market (transformer types)
Dry Oil
Insulation type Epoxy compounds, air and
others.
Oil
Market share in Russia up to 10% up to 90%
Cost high low
Reliability high low

5. 3. Problems of power transformer
Transformer with oil insulation:
The frequent occurrence of oil (the need for periodic monitoring)
Explosive
The need for protective structures, should not be placed near the human
flows
The need for frequent inspection (at least 1 time per quarter)
High operating costs for the Power Grid Company

6. Dry power Transformers:
Over time, the insulation material microcracks appear. They lead to
microbreakdown that entails eventually charring insulation
and short-circuiting the transformer (its failure)
Works range (-25C + 40C)
Afraid of dust
The need for frequent inspection (at least 1 time per quarter)
Expensive repair
High operating costs for the Power Grid Company

7. 4. Solution – Ceramic Insulation
We invented low-cost, having no analogues in the world technology
of application of ceramic insulation thickness of 300 microns on a winding
of the transformer by micro-arc oxidation.
microarc oxidation (MAO), is an electrochemical surface treatment
process for generating oxide coatings on metals
Oxidation occurs simultaneously with the process of winding

wire effective insulator

8. The advantages of ceramic insulation:
1. High, more than 0.9 winding factor (the ratio of total
conductor cross section (usually copper cross section) to
the area of the core window)
2. High temperature resistance;
3. High mechanical strength;
4. Radiation resistance;
5. Fire safety.
Aluminum wires in conjunction with ceramic insulation superior copper and
aluminium wires with dry or oil type of insulation on the mechanical and
temperature resistance.

5. Features of the New Transformer

10. Due to high insulating properties
of ceramics it is possible to use
very thin layer of ceramic that
provides a high (more than 0.9)
winding factor;
Small volume transformer
requires less material (steel) for
body
Winding density provides high
efficiency (low losses of electricity
power) even with aluminum wire,
comparable to dry and oil
transformers with copper windings
Reduce costs (aluminum is three
times cheaper than copper)
Low Cost Factors

11. 6. Applications
Transformer with ceramic insulation is beneficial in all areas
of traditional (oil and dry) transformer.
However, we want to highlight in particular:
The Far North and the zone of the tropics / subtropics
The possibility of the transformer to work at
wide temperature range (from -70C to + 70C) and any humidity
eliminating the need for design and construction,
installation of protective covers, booths, structures,
which gives substantial reduce in CAPEX
Transformers on drilling rigs
In conditions of relatively frequent changes
of location of the transformer, there is no need
to have housing for stabilize the temperature.
So this reduces CAPEX

12. Nuclear Power Plants
Transformer with ceramic insulation is absolutely radiation-resistant
in the United States at NPP there are widely used of radiation-resistant
«Nomex» insulation (provided by DuPont)
Nomex - an expensive synthetic aromatic polyamide, i.e. plastic.
Ceramic insulation has surely better performance
