kaapelityypin

Kaapelityypin is a Finnish term that translates roughly to 'cable type' and is used in electrical engineering and construction to denote a defined family or category of cables. In practice, kaapelityypin describes the specific design and performance characteristics of a cable, including conductor material, insulation, shielding, sheathing, and intended use. The term appears in technical specifications, procurement documents, and installation drawings to ensure the correct cable is selected for a given application.

Cables are classified by several criteria. Voltage rating (low, medium, or high), construction features (conductor material such as copper or aluminum; insulation such as PVC, XLPE, or EPR; shielding options; outer sheath materials), and application (power distribution, control and automation, data and communications, fiber optic). The classification also aligns with standardization systems, with international IEC and EN/CENELEC standards commonly used; Finnish standards (SFS) are typically harmonized with these schemes.

In practice, kaapelityypin informs procurement and installation: it helps determine suitable operating temperature, fire performance, mechanical durability, and environmental conditions (exposure to moisture, chemicals, or sunlight). Electrical engineers specify kaapelityypin to match system voltage, fault-current requirements, bend radius, and routing constraints.
