Cable boxes are equipment used within transformer systems to safely collect and protect power and connection cables. Transformers used in electrical transmission and distribution systems convert high-voltage energy to low-voltage levels suitable for end-use points. Cable boxes enable all electrical connections formed during this process to be made in an orderly and safe manner.

These enclosures, positioned on the transformer, protect cables from impacts, external influences, and electrical hazards, while also allowing for faster and safer installation, control, and maintenance activities.

Cable boxes can be manufactured from carbon steels such as S235JR, S355J0, S355JR, S355J2+N, and stainless steels such as SS304 and SS316L, depending on the conditions of use. This variety of materials allows the products to be designed for different applications requiring high mechanical strength, long service life, and corrosion resistance.
