Thermocouple EX ICAM Screen Extension 250V Cable

Description

The Thermocouple EX ICAM Screen Extension Cable range, comprises specialized multi-pair unarmoured instrumentation cables. Manufactured in compliance with IEC 60584-3, NF C 42-324, and NFC 32070 C2, these cables carry a standard instrumentation voltage rating of 250V. The internal construction consists of matched extension-grade alloys—a positive Nickel-Chromium (NiCr) wire and a negative Constantan (Copper-Nickel) wire—insulated with heat-resistant, flame-retardant PVC. The twisted pairs feature an Individual and Collective Aluminium/polyester tape screen (ICAM) layout with tinned copper drain wires, in a flame-retardant PVC outer sheath.

The specialized design delivers reliable resistance against weathering, UV radiation, and aliphatic or aromatic hydrocarbons, maintaining structural integrity and high signal clarity within a standard fixed operating temperature range of -20°C to +60°C.

They are suitable for pulling through underground plastic ducts and conduits, or for routing within indoor containment systems. They are also widely deployed above ground for fixed routing on open-air structures, external building walls, and industrial indoor or outdoor cable trays. During installation a minimum bending radius is strictly adhered to.
