"Jumper stay" refers to a device or mechanism used to support or stabilize a jumper, particularly in the context of electrical power transmission. A jumper, in this context, is a short electrical conductor that connects adjacent electrical conductors or terminals, helping to bridge gaps or create temporary connections.
The jumper stay is typically a metal or insulating structure that prevents the jumper from sagging or swinging due to gravity or external forces. It provides essential mechanical support and stability, maintaining the proper positioning and tension of the jumper. Jumper stays are commonly used in overhead power lines, electrical substations, and distribution systems.
In overhead power lines, the jumper stay is designed to withstand tension, compression, and bending forces while keeping the jumper securely in place. It helps prevent electrical contact between the jumper and other conductors or objects, reducing the risk of short circuits and potential damage to equipment.
Jumper stays can vary in design, depending on the specific application and requirements. They may include insulators, clamps, or brackets that secure the jumper to structures such as poles, towers, or structures specifically designed for jumper support. Additionally, jumper stays are often built with adjustable features to accommodate various lengths or to provide flexibility for changes in environmental conditions, such as wind or temperature fluctuations.
Overall, the jumper stay is an essential element in electrical power transmission systems, ensuring the stability, safety, and proper functioning of jumpers, ultimately contributing to the reliability and efficiency of electrical power distribution.
