The dry type transformer has eleven characteristics, as follows:
(1) no oil, no pollution, flame retardant, self-extinguishing fire.
(2) High insulation temperature rise grade: F insulation, transformer temperature rise up to 100K.
(3) low loss, high efficiency: SC(B)9 series loss than the current new national standard (GB/T10228) reduce 10%.
(4) low noise: SC(B)9 series distribution transformers can usually be controlled below 50dB.
(5) Small local discharge (usually below 10PC), high reliability, can ensure long-term safe operation, life up to 30 years.
(6) Crack resistance, temperature change resistance, high mechanical strength, strong resistance to sudden short circuit.
(7) Good moisture-proof performance, can operate normally under 100% humidity, and can be put into operation without drying treatment after shutdown.
(8) small size, light weight, according to the relevant statistics, the shape of the oil changed for more than 2 times the dry.
(9) There is no need for separate transformer room, no need for core maintenance and load-bearing beam, saving the occupation and space of civil construction; Because there is no oil, it will not produce toxic gas, will not cause pollution to the environment, do not collect oil pits and other auxiliary buildings, reducing the cost of civil construction.
(10) Convenient installation, no need for debugging, almost no maintenance; No need to replace and check oil, low operation and maintenance cost.
(11) Equipped with a perfect temperature protection control system to provide reliable guarantee for the safe operation of the transformer.
