  • Do cable tray seismic bracing systems need to be pre-made

    Do cable tray seismic bracing systems need to be pre-made

    Bolted connections are also commonly used, but they need to be designed with sufficient pre - tension to prevent loosening during seismic events. In areas with a high risk of seismic activity, the requirements for cable tray installations are often very strict. For over 60 years, the mechanical, electrical, and fire protection trades have relied on TOLCO seismic bracing solutions. Threshold rules, longitudinal vs transverse bracing, MSS SP-58/SP-127 and SMACNA guidance, and the hospital-specific I_p = 1. At a minimum, the cable tray designer should confirm: These inputs affect tray selection, brace layout, splice design, anchor demand, and. In this blog post, we will explore the key factors that need to be taken into account when designing cable trays for seismic resistance. These forces can cause ground shaking, which in turn can lead to the.


  • Structure of Wavelength Division Multiplexers for WDM Systems

    Structure of Wavelength Division Multiplexers for WDM Systems

    Normal WDM (sometimes called BWDM) uses the two normal wavelengths 1310 and 1550 nm on one fiber. Coarse WDM provides up to 16 channels across multiple transmission windows of silica. are then discussed with special focus on WDM Mux/demultiplexer (DeMux). The chapter concludes by highligh sy d components have been changing the landscape of communication as such. The constant push for. Wavelength Division Multiplexing (WDM) is a technique in fiber-optic communication systems that enables multiple optical signals with different wavelengths to be combined, transmitted, and separated over a single optical fiber.

  • Relays are a type of relay protection

    Relays are a type of relay protection

    The various protective functions available on a given relay are denoted by standard. For example, a relay including function 51 would be a timed overcurrent protective relay. An overcurrent relay is a type of protective relay which operates when the load current exceeds a pickup value. It is of two types: instantaneous over current (IOC) relay and definite time overcurrent (DTOC) relay.
