Kabelvulling

Kabelvulling is a Dutch term that translates to "cable filling" in English. It refers to material used to fill the interstitial spaces within a cable. This filling serves several important functions depending on the type of cable. In power cables, kabelvulling helps to prevent the ingress of moisture, which can degrade the insulation and lead to electrical failure. It also provides mechanical support to the conductors, preventing them from shifting and potentially causing short circuits or damage during installation or use.

For telecommunication cables, such as fiber optic or copper data cables, kabelvulling plays a crucial role in protecting the delicate fibers or wires from environmental factors and mechanical stress. Water ingress is particularly detrimental to fiber optic performance, and the filling material acts as a barrier. It can also help to cushion the components against vibrations and impacts. The specific type of kabelvulling used varies widely, including greases, gels, powders, and tapes, each chosen for its specific properties like viscosity, water-blocking capabilities, and compatibility with the cable's other components. The presence and type of kabelvulling are often specified in cable standards and manufacturer datasheets.
