What are the advantages and disadvantages of outdoor and indoor power transformers?

The parameters of outdoor design are higher than those of indoor power transformer, and bad weather should be considered in outdoor design. Outdoor design is superior to indoor design in waterproof, lightning protection and exposure, and the advantage of indoor design is low price. Transformer is a device that uses electromagnetic induction principle to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer) and so on. According to the purpose, it can be divided into: power transformer and special transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mine transformer, audio transformer, intermediate frequency transformer, high frequency transformer, impulse transformer, instrument transformer, electronic transformer, reactor, transformer, etc. ). t is usually used as the beginning of circuit symbols. Examples: T0 1, T20 1, etc.
