Strømskall

Strømskall is a term used in Norwegian‑language technical literature to describe the protective outer shell or enclosure of an electrical device or conductor. The concept encompasses the structural and insulating layer that surrounds current‑carrying parts to provide mechanical protection, electrical insulation, and safety for operators.

In practice, strømskall can be made of metal, plastic, or composite materials, and may be grounded or isolated depending on the design and safety requirements. Functions commonly attributed to strømskall include containment of moving parts, protection from accidental contact, reduction of electric field stresses on sensitive components, and, in some cases, shielding against electromagnetic interference. The design of a strømskall considers mechanical durability, thermal management, insulation thickness, and compliance with relevant electrical safety standards.

It is often used in equipment such as transformers, switchgear, motors, and cable assemblies, where a robust enclosure is essential for safe operation and ease of maintenance. The term is primarily used in Norwegian contexts and may not have a direct one‑to‑one equivalent in English‑language literature; related terms include electrical enclosure, housing, and insulation jacket.
