● Ambient temperature: -35℃~+40℃;
● Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%;
● Installation site: places without fire, explosion hazards, chemical corrosive gases, and with good ventilation, ground tilt not exceeding 3°.
Functional Features
● Fully insulated, fully sealed, maintenance-free, reliable guarantee of personal safety;
● Compact structure, volume only 1/3-1/5 of the same capacity European transformer, low height;
● Can adopt a split box structure to avoid oil contamination in the transformer oil tank;
● The high voltage side uses dual fuses for full range protection, greatly reducing costs;
● Can be used in a ring network or as a terminal, cable heads can be urgently plugged and unplugged at 200A load current;
● The low voltage side is equipped with an electronic phase loss protector, which can quickly disconnect the main incoming switch when abnormal voltage occurs in the system;
● High voltage side oil-immersed load switch or SF6 load switch, can be electrically upgraded, laying the foundation for achieving distribution network automation;
● Uses oil-immersed S11 or better performance S13 series transformers.
