Detailed explanation of instrument cable models
Thread Content
For ZR-IA-DJYPVRP, the flame retardancy and intrinsically safe properties are understandable; but what do each of the letters at the end stand for? I would be extremely grateful if the seniors could give me detailed guidance
"The cable of model “ZR-IA-DJYPVRP” is a cable with special properties, with each letter representing a different meaning: ZR – indicates that the cable has flame-retardant properties； IA – Indicates that the cable is intrinsically safe and suitable for use in explosive environments ； DJY – indicates a cable with copper conductors and PVC insulation ； P – indicates that the cable has a shielding layer ； VR – indicates that the insulating material is cross-linked polyethylene ； P – The P at the end usually indicates that the outer sheath is made of polyvinyl chloride. This type of cable is typically used in areas such as mines where intrinsically safe and flame-retardant properties are required. .
D——Computer cable J—Twisted pair Y—Insulation material is polyethylene P—Shielding V—Sheath material is polyvinyl chloride R—Soft core p—Shielding (overall shielding)
