Cable boxes are components used in transformer systems to ensure the safe routing, organization, and protection of power and connection cables. They enable all electrical connections required by transformers in power transmission and distribution systems to be carried out in an orderly and secure manner.

Mounted on the transformer, these enclosures protect cables against mechanical impacts, external factors, and electrical hazards, while also facilitating faster and safer installation, inspection, and maintenance activities.

Cable boxes can be manufactured from carbon steels such as S235JR, S355J0, S355JR, and S355J2+N, as well as stainless steel grades SS304 and SS316L, depending on operating conditions. This material diversity allows the products to be designed to meet varying requirements for high mechanical strength and corrosion resistance.
