Täytejohtimet
Täytejohtimet, or filler cables, are specialized electrical cables designed to fill gaps and provide structural support in conduit systems. They are commonly used in electrical installations where conduit runs are not completely filled with live conductors, such as in cable trays, raceways, or underground duct systems. The primary purpose of täytejohtimet is to prevent damage to the live cables by reducing movement and vibration, while also improving heat dissipation and fire resistance.
These cables are typically made from non-conductive materials such as polyethylene (PE) or cross-linked polyethylene (XLPE),
In Finland and other Nordic countries, täytejohtimet are regulated under electrical safety standards to ensure compatibility
While täytejohtimet are not energized, they play a crucial role in ensuring the longevity and reliability of
