isolatora

Isolator, sometimes written isolatora in some languages, is a device or component that provides isolation between two systems to prevent the transfer of energy, signals, or matter. The term covers several domains, including electrical, mechanical, optical, and thermal applications, and is used to improve safety, performance, or reliability.

Electrical isolators are devices that create a visible gap in a circuit to allow safe maintenance. They are designed to disconnect a portion of the network without carrying load current; the upstream protective device must de-energize the circuit, and the isolator provides a mechanical break with a clear air gap. In high‑voltage installations, isolators are arranged in banks and may include interlocks to prevent accidental reconnection.

Mechanical and structural isolators reduce transmission of vibrations, shocks, or heat between coupled parts. Examples include elastomeric mounts, spring isolators, and base isolators used in buildings and machinery. Seismic isolators decouple a structure from ground motion to limit earthquake damage.

Optical isolators, used in fiber‑optic systems, permit light to propagate in only one direction. They protect light sources such as laser diodes from back reflections and voltage transients, and they help prevent ground loops in sensitive measurement setups.

Other variants include thermal isolators that minimize heat transfer between adjacent regions, and electrical isolators that provide safety clearance in power plants and grids. In summary, isolators serve to separate systems while preserving desired functionality, depending on the context.
