Company patents

NKT HV Cables AB

NKT HV Cables AB's patent strategy reveals a strong, sustained focus on its core "Cables & Conductors" (73.4% of portfolio) and "Power Cable Installation" (40.5% of portfolio) categories, with the latter showing significant growth of +66.7% in 2025. While there's an emerging interest in "Ships & Marine Vessels" with a patent so far in 2026 after a patent in 2024, the sharp decline in filings across most categories in 2026 (e.g., "Cables & Conductors" down 75.0% and "Power Cable Installation" down 86.7% YoY, albeit with partial year data) suggests a potential shift in R&D priorities or a cyclical patenting pattern.

Pull-in head for a high voltage cable

Filed:2018-05-07Pub:2021-05-18
Applicant:NKT HV Cables AB

A pull-in head for a high voltage cable provided with a multi-wire conductor having an end portion which is stepped and tapering, with a layer-by-layer exposure of the wires in the direction towards the end face of the multi-wire conductor, wherein the pull-in head includes: a conductor clamp assembly having a plurality of clamping segments, wherein each clamping segment has an axial first central channel configured to receive the multi-wire conductor, wherein at least some of the clamping segments have mutually differing central channel width and central channel depth dimensions, the clamping segments being configured to be arranged one after the other in an order with a decreasing central channel width and central channel depth dimension, the central channel width and central channel depth dimensions being adapted to the tapering stepped configuration of the multi-wire conductor, whereby the first central channels together form a multi-wire conductor channel which is tapering in an axial direction, and wherein each clamping segment is configured to provide individual clamping of the multi-wire conductor, and a hollow lifting head configured to receive the conductor clamp assembly, wherein the conductor clamp assembly includes a support structure, wherein the clamping segments are configured to be assembled with the support structure to thereby clamp the multi-wire conductor between the clamping segments and the support structure.
