Designed to protect power and equipment cables from the effects of elevated levels of radiant heat. Available in standard 3m lengths or purpose built per application. Rated for Class 1, Div 2 hazardous locations. Conductor:. Cable Shield is the drain wire attached with Aluminum Mylar or metal braid cover on the instrument signal cables i. 4-20 mA analog signal, low voltage digital signals, etc Main cable (i. control system end. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. Reliability—even in the harshest of environments—is the hallmark of Belden's instrumentation cables. No matter the gauge size, conductor count, insulation, jacket, armor or rating you need, Belden can accommodate your. It is specifically engineered with twisted pairs or triads, foil and braid shielding, and drain wires to maintain signal integrity in electrically noisy industrial environments. This guide covers instrumentation cable construction, NEC/UL ratings (PLTC, ITC, TC), shielding configurations, conductor. Application: UL standard tray cables for transmission of digital or analogue signals in instrumentation applications. Standards & Voltage Rating: UL13 UL2250, UL1685, UL1277.
