Zuleitung

Zuleitung is a German term used in technical contexts to denote a supply line or feeder that carries a service from a source to an end point. It is a generic concept that can apply to electrical power, water or gas supply, or telecommunications, and is distinguished from branches that split the flow further along a system.

In electrical engineering and building services, a Zuleitung refers to the conductor that brings electrical power from a distribution point to a device or circuit. It may be a fixed installation conductor or a flexible cord connected to a device. Permanent Zuleitungen are part of fixed wiring and are protected by protective devices; flexible Zuleitungen are used for portable equipment. They must meet standards for insulation, voltage rating, and fire safety. Color coding and labeling indicate function and are chosen according to local regulations and current requirements.

In plumbing, a Zuleitung is the supply line delivering water or gas from the main to fixtures or appliances. It can consist of copper, plastic (such as PEX or PVC), or other materials, and is designed to withstand pressure and prevent leaks. Installation follows building codes and typically includes shut-off valves and proper fittings, with attention to material compatibility and corrosion resistance.

In telecommunications and building infrastructure, Zuleitung may describe the feeder that carries signals from a distribution point to a subscriber line, such as coaxial or fiber-optic cables. The term highlights the role of these lines as primary connections that feed a downstream network or device.

Overall, Zuleitung denotes the essential conduit that supplies a service from its source to its endpoint, across various engineering disciplines.
