Pre-fabricated Compact Substations
YB series of the pre-installed substation (hereinafter referred to substations) is in line with the standard of GB / T17467-1998 High voltage and low voltage prefabricated substation. This substation series is the combination of shell, transformer, low-voltage and high-voltage switchgear. It is a new type of complete equipment that can penetrate the load center.
The pre-fabricated compact substation has advantages of small volume, beautiful appearance, safe and reliable operation, less maintenance and convenient installation. The case of it has the function of ventilation and heat insulation. The high-pressure side adopts gas load switch, pressure-operated load switch, vacuum load switch, sulfur hexafluoride load switch. It has five prevention function. The protection performance of this kind of substation is perfect. It is equipped with temperature control ventilation device which can meet the requirements of various regions.
