Old transformer blocks
Transformers come in all sorts of sizes and designs. An electrical transformer is often abbreviated as “trafo” in the Netherlands or “transfo” in Flanders, and its purpose is to increase or decrease the voltage.
Transformer blocks are often recovered during the demolition of industrial facilities, but they are also used, for example, in older welding carts. When dealing with larger quantities, it is worth keeping this type of material separate from mixed electric motors, as the copper content—and thus the value—is higher. If a transformer is defective or has reached the end of its service life, it becomes scrap and must be recycled.
Transformer blocks must be free of oil, dirt, grease, and any attached peripheral equipment such as capacitors. PCB-containing oil transformers are not accepted. Because there is such a wide variety of grades and sizes, it is more difficult to determine the exact price, as it all depends on the content of the various metals. Transformer cores with copper-clad aluminum or aluminum cores are worth less and should be offered as a separate grade.
Examples of transformer blocks

Price of Old Transformer Blocks
Transformers are used to increase or decrease electrical voltage. These devices are found in many different types of systems, ranging from industrial machinery to power supplies. In the Netherlands, a transformer is often referred to as a "trafo."
When transformers fail or when equipment is replaced, these components are removed and sold as scrap. The value of transformer cores is largely determined by the metals they contain, such as copper, steel, and sometimes aluminum.
Because transformers can vary greatly in size and composition, the price may vary depending on the type and model.
