  • Publication number: 20170054236
    Abstract: A connector (1) for two electrical energy cables is indicated. The connector (1) has a plug (2) and a socket (3) which each is able to be tightly connected and suitable to produce a releasable electrical contact between the conductors. The socket (3) has hollow space (12) running in the longitudinal direction and the plug (2) a protruding bolt (11) in the longitudinal direction which is pluggable in the hollow space (12). The hollow space (12) and the bolt (11) have the identical truncated conical shape to each other, so that the bolt (11) is fixable in the hollow space (12) in the operative position. The connector (1) has further a pin (15, 18) so arranged that its axis is right angled to a connector axis (10) of the connector (1) and interacts with a circumferential recess (17, 18) around the diameter of the bolt (11).

  • Publication number: 20150104659
    Abstract: A polymer resin composition has EPDM (Ethylene Propylene Diene Monomer) as a base resin. The composition further has the following components based on 100 parts by weight of the base resin: 1 to 5 parts by weight of amine-based antioxidant, and 1 to 5 parts by weight of HALS (Hindered Amine Light Stabilizer). An insulating material can be manufactured using the polymer resin composition providing good thermal stability and also an extended lifespan under high temperatures. Such an arrangement is particularly suitable for use in cables for nuclear power plants.
