3-Dimensional Wound Core Open Ventilated Dry-type Transformer Product Features > It is of 3-phase equilibrium, compact structure, lower losses, slighter noise, less material consumption by virtue of 3-dimensional wound core; > There are no liquids to spill, explode or burn, and NOMEX does not support combustion in air. In the case of a building fire, NOMEX products do not produce significant amounts of toxic smoke or dangerous particles. > Since dry type transformers insulated with NOMEX can be located close to their loads - inside factories, schools, hospitals and apartments - low-voltage lines can be shortened. > Adhering to US DuPont RELIATRAN Technology, insulation Class-C(220) NOMEX system Approved by UL and solventless insulation varnish produced by Germany ELANTAS, 3-Dimensional Wound Core Open Ventilated Dry-type Transformer is of better security performance, great overload capacity, high reliability and satisfactory service lifetime; > 150 C-rise units insulated with NOMEX require less conductor and core steel, resulting in lower initial cost. This reduced size and weight contributes to ease of installation, especially since no vaults or catch basins are required. Smaller cores also mean lower no-load losses; > Surveys published by IEEE show failure rates of modern open ventilated dry type transformers equivalent to conventional liquid-filled units in the same power and voltage classes. Repair time for dry type units is also considerably shorter; > Since the properties of densified NOMEX papers are insensitive to moisture, open ventilated transformers insulated with NOMEXR perform satisfactorily in the most humid environments. This allows the placement of OVDT units in many locations not considered in the past; > At the end of their useful life, VDT units can easily be dismantled, and the copper conductors recovered, along with the steel core;
