IA-DJYP2VP2 2*2*1.5 Shielded Computer Cable for Intrinsically Safe Circuits
I. Product Features and Applications
This product features low capacitance and inductance, excellent shielding and anti-interference properties. Made of imported fluoroplastic and fluororubber, this special high-temperature computer cable can operate in environments ranging from -40°C to 260°C for extended periods. It is flame-retardant and resistant to acids, alkalis, oils, and water. Designed specifically for intrinsically safe and explosion-proof circuits, it can be installed not only in cable trays but also in cable trenches and direct burial. This special high-temperature intrinsically safe computer cable was awarded a national patent in 2000. It is suitable for use as a transmission line in distributed control systems and automated testing systems requiring explosion-proof protection and other harsh environments. Its explosion-proof safety performance significantly exceeds that of standard DCS cables and computer control cables.
