Thermocouple EX ICAM Screen Extension 250V Cable

Description

The Thermocouple EX ICAM Screen Extension Cable range, supplied by Cleveland Cable Company, comprises specialized multi-pair unarmoured instrumentation cables engineered for transmitting precise temperature measurement data from Type E thermocouple sensors. Manufactured in compliance with international and European specifications including 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. To eliminate crosstalk and severe external electromagnetic interference across long routing distances, the twisted pairs feature an Individual and Collective Aluminium/polyester tape screen (ICAM) layout with tinned copper drain wires, all enclosed in a robust, flame-retardant PVC outer sheath.

Engineered for dependable use across industrial monitoring sectors, this unarmoured cable is designed for noise-heavy environments subject to high levels of electrical noise, crosstalk, and chemical exposure where mechanical risks are minimal. It is widely utilized in power generation stations, petroleum refineries, chemical processing facilities, and manufacturing plants where continuous, accurate multi-point temperature tracking is critical. The specialized outer jacket 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.

For general installation, these unarmoured multi-pair extension cables 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 to securely link field-mounted sensors to control room panels. During installation, standard parameters dictate that care must be taken to maintain the structural layout, ensuring that a minimum bending radius is strictly adhered to after fixed installation to preserve continuous screening performance and signal accuracy.
