  • Description
  • Data Sheet
  • Product Introduction

    YB-Z.G-40.5 series modular transformer is a type of substation solution for the photovoltaic power generation, and has been large wide used in the world, and this is developed design with the joints of the 10kV, 35kV modular transformer and the advanced technology combined technology of the world. YB-ZG-40.5 substation has the transformer, load switch, and the HV fuses installed in the shell of transformer, and keep transformer insulation liquid as the entire product insulation and cooling medium. The structure of the system is full sealed design, and be treated by split, shot blast, pickling and phosphate, and the shell is treated by spraying primer, the middle cost and top paint for the corrosion resistance, paint thickness and UV resistance, which has far difference as the normal paint treatment. The system is designed with the advantages of small size, light weight and easy installation. In addition to the product to meet the relevant standards of the components, the system is also complied to the stand of JB / T10217-2000 for ‘modular transformer’.

      According to user requirements, PV substation’s LV side can provide the functions of voltage missing and less voltage protection. When HV side lost any phase, the LV side can be automatically shut off. The LV side of system can equip with power electricity, controlling electricity and lighting maintenance transformer etc.. The system must be equipped with the functions of the telemetry and remote communication. As PV power generation’s hard working conditions, the LV main circuit breaker must be the type of low-temperature circuit and provide the test report of -40 ± 3℃, duration 16h, 120 times operation performance and 30 times / hour.
