FC Underground Cable 6GK1 830-3FH10

The FC underground cable 6GK1 830-3FH10 meets the requirements of EN 50170, cable type A, with solid copper cores (22 gauge). The internal structure of the cable corresponds to that of the standard LAN cable, the electrical characteristics are identical. The cable has an additional PE outer sheath. The outer and inner sheath are bonded together so that the FC underground cable can be fitted with all SIMATIC NET PROFIBUS connectors after removing the outer sheath.

After removing the outer sheath, the structure of the cable also allows use of the FastConnect (FC) stripping tool for fast stripping of the inner cable (see Section 4.2.3).

Properties

The characteristics of the underground cable differ from those of the standard LAN cable as follows:

SImproved resistance to abrasion

SImproved resistance to oil and grease complying with VDE 0472, Part 803, Test Type B

SResistant to UV radiation

SLarger outer diameter and heavier

SThe sheath material is flammable

SResistant to water and steam
