Decoding HELUDATA® UL 2919 cable through its outer sheath

HELUDATA® UL 2919 is one of HELUKABEL’s signature UL-certified data cables. Commonly used in industrial automation and process control systems, this cable stands out for the characteristics encoded on its outer sheath:

*Take HELUDATA® 2919 PE/PVC-TP-C 30 GREY for example.

This marking indicates the materials used for the insulation and outer sheath:

- PE (Polyethylene): The insulation material surrounding tinned copper conductors, ensuring stable signal transmission and low attenuation.

- PVC (Polyvinyl Chloride): The outer sheath material, providing excellent mechanical strength and resistance to environmental impacts.

This describes the core structure and shielding of the cable:

- TP (Twisted Pair): Each pair of conductors is twisted with optimal lay lengths and wrapped with plastic-coated aluminum foil (St) to minimize electromagnetic interference (EMI) and crosstalk between pairs.

- C: Indicates that the cable includes an overall shield - a braided screen of tinned copper wires. This provides superior protection against external interference. If the “C” is absent, the cable doesn’t have a braided screen.

“GREY” denotes the color of the cable’s outer sheath - grey, which is commonly used for data or control signal cables in industrial environments. In addition, the sheath of HELUDATA® 2919 features meter marking, allowing users to easily measure and cut the desired cable length accurately during installation.

These two codes refer to the UL certification (Underwriters Laboratories):

- E170315: The UL File Number assigned to HELUKABEL GmbH, confirming that the manufacturer is officially UL-recognized. This number can be looked up to verify product authenticity.

- UL Style 2919: A UL standard defining the technical requirements for multi-conductor cable with non-integral jacket, including specifications for voltage, temperature, insulation, shield, jacket…

These values specify the safe operating limits of the cable:

- 80°C: The maximum operating temperature, ensuring safe and stable performance in industrial environments (temperature range: -30°C to +80°C).

- 30V: The peak operating voltage, ideal for signal transmission and industrial data communication (not for high power current installation purposes).
