Why should we apply TRAFO TECH transformers ?

• They have the only, patented insulation method using two kinds of polymers.
• They have the hermetic insulation of plastics, not passing moisture and gases inside the transformer.
• Insulation between the windings is checked up with voltage 400V 50Hz or higher /depending on requirements /.
• They resist rapid and high temperature fluctuation.
• They are resistant to chemical compounds.
• They are resistant to bacteria, fungi, moulds.
• Hermetic insulation prevents the transformer core corrosion and therefore it secures the fixed parameters of the transformer during its operational use.
• They have housings easy to install, resistant to impact.

Transformers made in TRAFO TECH technology are adapted to install in heavy weather conditions: on air, in gardens, in bathrooms, pools, quays, in sea and tropical conditions.

CHARACTERISTIC FEATURES OF TRAFO TECH TRANSFORMERS

TRAFO TECH transformers are characterised by low losses in the form of heat. It is the accepted rule to adapt the maximal temperature of the transformer at the rated load to the Customer’s requirements. In standard performance is assumed the maximal temperature increase by 50⁰C at the rated load.

TRAFO TECH transformers are characterised by the hermetic insulation of transformer windings preventing the core corrosion, due to what the electrical parameters of the transformer are kept on the fixed level for the whole period of its use, what in its turn guarantees its proper operation and minimizes the losses of electric energy in time.

TRAFO TECH transformers are characterised by the hermetic insulation of the transformer windings preventing penetrating moisture and gases to the windings, what prevents the damages of the transformer during its use. Hermetic insulation is made of specially selected plastics, resistant to high temperature fluctuations, living organisms and to the chemical compounds, what allows to use them in the unfriendly environment.

Due to the application exclusively of the toroidal cores made of the high quality magnetic materials as well as due to the special scrupulousness in symmetrization of windings in connection with the appropriate insulation, TRAFO TECH transformers are characterised by the maximal reduction of radiation outside and by the maximal rejection of signals transmitted by the transformer in the wide frequency band. Due to that TRAFO TECH transformers find their application in supply systems of the secured systems and information centres („Tempest” Class).

Due to the low radiation outside and maximal rejection of signals transmitted by the transformer in the wide frequency band, and due to the low quantity of heat emitted, overload ability and due to the fact, that as the only one they allow using disinfecting and decontaminating agents thereon they are perfectly fit for the safe supply of the medical equipment.

TRAFO TECH transformers are characterised by the very high reliability and accuracy of performance (failure frequency and spoilage ratio below 0.05%). Standard warranty period for TRAFO TECH transformers amounts to 3 years.

ADVANTAGES OF TRAFO TECH TRANSFORMERS

TRAFO TECH transformers are made in special insulation technology securing:

• Protection degree IP65 /it means: first digit - dustproof insulation, second one - protection against water penetration and its harmful effects, poured in stream onto a transformer /
• Performance of the transformer insulation coats using two kinds of plastics A - infusible after polymerisation, inflammable, with working temperature up to 170 ⁰ C and the second one, B, self-regenerating with the softening point at 105⁰C. On special request we make transformers with the insulation with plastic A only.
• Hermetic insulation coats, not passing any liquids and gases inside the transformer
• Possibility to operate for the transformers in any weather conditions
• Possibility to operate for the transformers at 100% humidity
• Possibility to operate for the transformers immersed in aggressive liquids
• Possibility to operate for the transformers at rapid changes of temperatures and pressure
• Fastness of insulation coats to chemical compounds and living organisms
• Protection of transformer core against corrosion,
• Maintenance of fixed transformer parameters for a time, due to absence of penetration of gases and liquids inside the transformer and protection of the core against corrosion.

Energy savings:

Due to the application of toroidal cores of the highest parameters in TRAFO TECH transformers we achieve the energy savings.

Typical transformer with a core composed of plates has an efficiency not exceeding 96, TRAFO TECH transformer – approximately up to 98.

For example, transformer TRAFO TECH 10 000 VA in comparison to the competitive one /typical transformer of competing manufacturer, composed of plates has the efficiency not exceeding 0.94, TRAFO TECH transformer – not less than 97 /

TRAFO TECH transformer gives the energy savings 0.44 Kva. Annually, it gives the saving

of 0,44kVA*8500 hours = 3740 kWh / kilowatt-hours/ what gives, at the full day price of

1kWh = 0.40 zł 0.40 zł * 3400 kWh = 1 360 zł.

TRAFO TECH INSULATION TECHNOLOGY

Insulation technology has been developed especially for the French atomistic physics. Transformer insulation technology is patent protected. Insulating coats are characterised by the extremely high resistance to weather conditions, environment pollutions and living organisms. Transformers made in this technology have hermetic insulating coats, which do not allow liquids and gases to penetrate the transformer interior. Insulation is made of two especially selected plastics, which are subject to polymerisation during the process of insulation. Plastic A has the properties of self-regeneration of the insulation properties.
