Abstract: AMF contact for vacuum interrupter, with concentric opposing contact pieces, wherein the contact pieces consist of an external electrode shaped like a coil with a plate as bottom plate of the electrode, and generating a strong axial magnetic field, and an inner internal electrode as top electrode, carrying the nominal current, according to the preamble of claim 1. In order to to design the outer electrode in order to generate the axial magnetic field as requested for the application, with potentially superior performances to the competitors, the invention is, that between the top electrode and the bottom plate is arranged a rod, which is at one end fixed at that lower side of the top electrode and the other end of the rod is guided trough an opening of the bottom plate, wherein at that end of the rod the rod is being furnished with an extended head in such, that the extended head of the rod locks or tightens the rod in a defined axial position. Furthermore the solution can be applied for the standard AMF or TMF (cup) contacts to reinforce them.

Abstract: A high-voltage DC cable joint comprising a multi-wall layered construction having individual concentrically arranged layers. The joint comprises, from inside to outside, an inner conductive rubber layer (1), a field grading rubber layer (2) made from a predetermined tailored formulation, an insulating rubber layer (3) and an outer conductive rubber layer (4). The field grading rubber layer separates and interconnects the conductive rubber layers, and wherein the rubber layers are cross-linked by a by-product-free manufacturing method. The cable joint is preferably made from platinum cured rubbers by moulding process steps. In a preferred embodiment the cable joint is made by injection moulding.
