EB1904A

Product catalog summary

Overview: The document describes the specifications and applications of the EB1904A-Ed1 overall screened, unarmoured instrumentation cable, which is flame retardant, fire retardant, resistant to electromagnetic interferences, UV resistant, and ROHS compliant.

Standards: The cable complies with standards NF M87-202, UTE C 32-014, NF C 32-020, IEC 60332-1, and IEC 60332-3-24.

Description and Application: These cables are designed for safety extra-low voltage applications in petroleum and petrochemical units, particularly for transmitting AC or DC analogue signals. They are unarmoured, suitable for environments without mechanical damage risk, and have sheaths resistant to aliphatic hydrocarbons.

Construction:

Conductors: Made of solid or stranded annealed copper according to IEC 60228, available in different models with varying wire diameters and sections.
Insulation: 90º PVC.
Cabling Elements: Configured in pairs or triads, with quad configuration for 2-pair cables.
Core Identification: Natural, red, blue, and yellow colors, numbered on the natural conductor.
Core Wrapping: PETP tape with a minimum 30% overlap.
Collective Screen: Tinned copper drain wire with aluminium/PETP laminated tape.
Outer Sheath: PVC resistant to aliphatic hydrocarbons, marked with manufacturer details and other customer-specific marks.

Electrical Characteristics (at 20ºC):

Conductor resistance varies by model, with values of 36.8, 21.4, and 12.3 Ω/km.
Minimum insulation resistance is 500 MΩxkm at 20ºC, 500 Vdc.
Mutual capacitance ranges from 145 to 180 nF/km at 800 Hz.
Operating voltage is 300/500 V, with test voltages of 1,500 Vac and 2,000 Vcc for 1 minute.

Mechanical Characteristics:

Operating temperature ranges from -25ºC to +90ºC.
Installation temperature ranges from -5ºC to +50ºC.
Bend radius is 10 times the cable diameter.
Flame propagation and fire properties comply with UNE-EN 60332-1-2 and IEC 60332-3-24.

Size, Dimensions, and Weights: The document provides detailed tables for different models (0.5 mm², 0.88 mm², and 1.5 mm²) with specifications on the number of elements, diameter under armor, overall diameter, nominal weight, and standard delivery drum type.
