Overview

Currently, the global energy crunch and the growing emphasis on environmental protection have made the improvement of energy efficiency and the development of renewable energy sources two key aspects of sustainable energy development. Renewable energy sources, such as wind and solar energy, are receiving increasing attention and are considered to be the most promising avenue for the large-scale development and application of “green energy”.

In China, in order to transmit electricity over long distances, the export voltage of wind or photovoltaic (PV) generating units needs to be boosted to 690 V. Typically, cables are used to connect the generators to specialized box-type step-up transformers. These transformers step up the voltage to 40.5 kV or 12 kV, which is then transmitted to the central substation of the wind or PV farm. The voltage is then further boosted and the power is fed into the grid.

Therefore, our company designs and develops 40.5 kV and 12 kV wind power step-up transformers and photovoltaic step-up transformers to meet these requirements and to achieve optimum performance.

Installation

Product acceptance, installation and commissioning
  1. Users are advised to carefully inspect the received goods in accordance with applicable regulations. In the case of immediate installation, the items should be stored in suitable locations that conform to normal usage conditions. Additionally, it is important to ensure the proper preservation of the box transformer.
  2. The foundation of installation shall be made in strict accordance with the foundation drawing provided by the manufacturer or jointly formulated by both parties.
  3. Theinstallation site shall have sufficient loading and unloading space, and the unloading shall also run according to the loading requirements.
    The installation foundation should be constructed strictly according to the manufacturer’s provided foundation drawing or a mutually formulated plan. Sufficient space should be available at the installation site for loading and unloading equipment, and the unloading process should adhere to the specified loading requirements.
  4. The gap between the base and the foundation of the box transformer shall be sealed with cement mortar to prevent rainwater from entering the cable room.
  5. To prevent rainwater from infiltrating the cable room, it is imperative to seal the gap between the base and the foundation of the box transformer using cement mortar. This will effectively create a barrier, safeguarding the cable room against water ingress
