  • What types of electrical quantities are protected by relays

    What types of electrical quantities are protected by relays

    In a power system, relays are devices that monitor the flow of electrical quantities such as current, voltage, frequency, or impedance. This guide explains the main categories—from basic electromechanical relays to modern solid-state and protective types—so you can choose the right relay for your project. Engineering use: Relays are used on feeders, transformers, buses, motors, generators, and transmission lines to protect equipment and improve system. A relay is an electrically operated switch that uses a small electrical signal to control the opening or closing of one or more sets of contacts in another circuit.


  • Why are steel wire protective sleeves used on optical cables

    Why are steel wire protective sleeves used on optical cables

    Splice protection sleeves play a critical role in maintaining the mechanical integrity of fiber optic networks. They reinforce fragile splice joints, preventing bending, cracking, or breakage, especially during installation and cable handling. A protection sleeve is made up of three parts: An outer shrinkable tube made of heat shrink plastic, an inner tube or fiber tube where the fiber is placed. Fiber optic sleeves are an essential component of fiber optic cables that play a critical role in ensuring optimal transmission of light signals. These protective devices help to protect fiber strands from damage caused by physical stress, environmental factors, and other external factors that can. iFiber Optix Fiber Optic Splice Sleeves protect and reinforce fusion-spliced fiber connections — restoring the mechanical strength of the spliced fiber and shielding the splice point from environmental stress, physical disturbance, and long-term degradation.
