Instrumentation Cables—XLPE Insulated,Individual & Overall Screened, DRYLAM Layered,Wire Armoured PVC Sheathed Cables(CU/XLPE/IOSCR/DRYLAM/SWA/PVC)
Instrumentation Cables with XLPE Insulated, Individual & Overall Screened, DRYLAM Layered, Wire Armoured and PVC Sheathed construction (CU/XLPE/IOSCR/DRYLAM/SWA/PVC) are engineered for high-accuracy signal transmission in harsh and moisture-prone environments. XLPE insulated copper conductors deliver excellent dielectric strength, thermal stability, and long-term electrical reliability.
Individual and overall screening effectively suppress electromagnetic interference and cross-talk, ensuring stable and precise signal performance in complex control systems. The integrated DRYLAM water-blocking layer prevents longitudinal and radial water penetration, protecting the cable core without increasing overall diameter. Steel wire armour provides strong mechanical protection against impact and external stress, while the PVC outer sheath offers resistance to abrasion, oils, and chemicals. This robust cable design ensures dependable operation, extended service life, and consistent performance in demanding industrial applications.

Raw Material Test
Raw Material Test is the first quality control step for CU/XLPE/IOSCR/DRYLAM/SWA/PVC instrumentation cables. Copper conductors are tested for electrical conductivity, tensile strength, and dimensional tolerance. XLPE insulation compounds undergo thermal aging, elongation, and insulation resistance testing. Individual and overall screening materials are inspected for conductivity, coverage density, and shielding performance. DRYLAM water-blocking tapes and yarns are evaluated for swelling behavior and moisture absorption efficiency. Steel wire armour is tested for mechanical strength and flexibility, while PVC sheath materials are examined for flame retardancy, abrasion resistance, and environmental durability. Only qualified materials proceed to production.
Process inspection
Process Inspection ensures consistent manufacturing quality of CU/XLPE/IOSCR/DRYLAM/SWA/PVC instrumentation cables. XLPE insulation extrusion is monitored for concentricity and thickness accuracy. Individual and overall screening processes are inspected to ensure complete coverage and electrical continuity. DRYLAM layering is carefully checked for correct placement and effective water-blocking performance. Armouring operations are controlled for wire tension and lay length, ensuring mechanical integrity. PVC sheathing is inspected for surface quality and dimensional stability. Continuous in-process inspections maintain compliance with design and technical standards.
