Applications
CORFLEX® cables may be found in a variety of industrial, commercial and utility applications. Chemical, oil and gas, and forestry industries plus commercial or high-rise buildings are areas in which CORFLEX® has gained acceptance.
Exceptional fire ratings (as per appropriate specifications), impact-resistance, flexiblity and an impervious metallic sheath are key components of this design.
CORFLEX® installation may be in wet or dry locations, in trays, troughs, wireways, directly buried or embedded in concrete. As well, it can be used in plenums (with no outer coverings), ducts and other airways per NEC 2008 and NEC 2011 Article 300.22.
The 300 volt CORFLEX® PL cables can be installed in Class I, II, III & intrinsically safe locations & Division 2 as per NEC 2008 and NEC 2011 (PLTC and ITC Rated).
CORFLEX® PL cables are suitable for control, signal, and instrumentation circuits with 300 volt rating. The cable construction minimizes noise and signal interference to enhance performance in instrumentation, dataflow, computer & datalogging applications especially in areas where high voltages or high currents are present.
The 600 volt and higher CORFLEX® cables can be installed in hazardous locations designated Class I, II & III and Divisions 1 & 2 as per NEC 2008 and NEC 2011 (HL Rated).
CORFLEX® MC cables are designed for use on power and control circuits with 600 volt rating. Cables are suitable for use as feeders and branch circuits for power, control, lighting and signalling as per NEC 2008 and NEC 2011 Articles 330, 725 & 727.
CORFLEX® VFD cables are designed to improve the operating performance of variable frequency drive systems. The 600 volt CORFLEX® VFD cables provide excellent shielding from high frequency noise that can interfere with data and control signals. One of the advantages of the Nexans CORFLEX® sheath compared to other constructions is that the cable sheath provides a long term low resistance path to ground to protect the drive system. The cable grounds provide the best cancellation and lowest net injected ground current into the drive system, protecting against common mode currents which impair the drive unit electronic performance and shorten the drive's life span. Cable grounds, in combination with the aluminum sheath, ensure a balanced, very low resistance path to ground to reduce the chance of motor failure due to bearing currents.
