    DESCRIPTIVE REPORT
    MULTIPLE LAYER CONDUCTOR PIN FOR AN ADVERSE ENVIRONMENT CONNECTOR OR PENETRATOR AND METHOD FOR MAKING A MULTIPLE LAYER CONDUCTOR PIN FOR AN ELECTRICAL CONNECTOR OR ADVERSE ENVIRONMENT PENETRATOR
    Basics 1. Field of the Invention
    The present invention generally relates to the electrical connector or penetrator assemblies for connecting two cables or connecting a cable to electrical equipment, and is particularly related to a multi-layer conductor pin for incorporation into electrical or hybrid connectors or penetrators for subsea or use in other harsh environments, and a multi-layer pin manufacturing method.
    2. Related technique
    Electrical connector or penetrator units include one or more conductors or conductor pins that extend through the units to carry current between opposite ends of the connector or penetrator, connecting two cables or a cable and electrical equipment. Usually, these conductors are surrounded by a sealing sleeve or have an external sealing layer. In a typical electrical penetrator or feed through arrangement, a conductor pin extends through a hole in a sleeve or sealing body. In a typical electrical connector, plug and receptacle units or connector parts are each connected to cables or other devices intended to be joined by the connector to form complete circuits. One or more connector pins or probes extend through the plug unit and are designed for plug-in coupling with one or more sockets aligned to the receptacle unit. In each case, the conductive pin is surrounded by the appropriate seal along at least part of its length.
    The partial discharge at high AC voltages between conductor and seal in typical connectors and penetrators is a problem of long-term reliability. In a connector / penetrator the seal is usually formed by overmolding the conductor or fitting a sealing sleeve or layer over the conductor. In both methods, it is not possible to eliminate
