Kuparijohtimille

Kuparijohtimille is a Finnish grammatical form used to indicate suitability, destination, or applicability “for copper conductors.” It is the allative plural form of kuparijohtimet, meaning copper conductors, and appears in technical and instructional writing to specify which materials or components a product is intended to work with.

In Finnish technical language, the -lle suffix often marks the target or recipient of an action or property. When combined with a plural noun like kuparijohtimet, kuparijohtimille conveys that a device, material, or instruction is to be used with copper conductors. The form is common in product catalogs, installation guides, and safety instructions to communicate compatibility without listing every possible conductor type.

Usage examples include phrases such as "soveltuu kuparijohtimille" (suitable for copper conductors) or "käytä kuparijohtimille tarkoitettujen liittimien kanssa" (use with connectors intended for copper conductors). The construction helps differentiate copper conductors from alternatives, such as aluminum conductors, which would use a corresponding form like alumiinijohtimille.

Notes on variation: the singular form would be kuparijohtimelle (to a copper conductor) and similar patterns exist for other materials (for example, alumiinijohtimille). Although kuparijohtimille is primarily a linguistic and technical label, it reflects common Finnish practice of tying product specifications to material compatibility in a concise, standardized way.
