  • Ground wire at the bottom of the cable tray

    Ground wire at the bottom of the cable tray

    Cable tray grounding wire is the safety connection that links your electrical system's cable tray to the ground. The metal in cable trays may be used as the EGC as per the limitations. The Cable Tray Grounding Wire ensures everything runs safely and smoothly. Consider it as an emergency electricity exit. For systems with 110kV and above, where the neutral point is effectively grounded, the metal sheath of single-core cables should be directly connected to the substation grounding. There are three wiring options for providing an EGC in a cable tray wiring system: An EGC conductor in or on the cable tray. Each multi-conductor cable with its individual EGC conductor.

  • How long should fiber optic strippers strip

    How long should fiber optic strippers strip

    Use the fiber strippers to strip ~1" (25mm) from the end of the fiber in 3 steps, about 1/4-3/8" (6-8mm) at a time. Hold the stripper at a 45degree angle to the fiber to reduce stress on the fiber. In some applications, “window strip” operations are required, where a short section of coating is. Without question, good stripping techniques in your fiber optic cable assembly process are imperative. Eventually, this imperfection can initiate a crack when the. At its core, an optical fiber stripper is a specialized tool engineered to precisely remove the protective polymer coatings from an optical fiber without damaging the delicate glass core and cladding beneath. The typical fiber optic cable has multiple layers: the outer jacket, strength members. Consider that fiber optic cable dimensions are discussed in terms of microns (µm) and you may start to realize that the tools required for any level of fiber optic preparation must be durable, reliable, and extremely accurate. In this blog we will specifically highlight and discuss the trueCABLE. For fibers with a non-standard outer diameter, we recommend an adjustable stripper.
