Abstract: An electrical line is to be insulated from fluid or corrosive media penetrating along the electrical line in an advantageous and cost-effective manner from the standpoint of production engineering. The electrical line having an electrically conductive inner conductor and an insulating jacket surrounding it includes a sealing element, which is disposed on the insulating jacket in a spring-back manner via a first subsection, and which covers the inner conductor across a partial length via a second subsection. The sealing element contains a soluble, in particular fluid sealant, which is pressed into the individual conductors of the inner conductor implemented as stranded wire, and cures in a sealing manner. The electrical line is used, for example, in the automotive industry for a cable harness plug.

Abstract: A system that finds breaches in solid insulation, as well as detecting insufficient air gaps between conductors. The invention solves problems in how to detect breaks in solid insulation by applying high voltages without damaging the solid insulation. The invention also overcomes limitations where the voltages required to detect an insufficient air-gap can cause damage to, or are difficult to apply to the electrical device under test. The system for testing conductors held physically separated or otherwise isolated from each other by an insulating material is composed of a high-voltage breakdown tester, a means of connecting the tester to the conductors, and an added gas that is used to displace air in the proximity of the conductors.

Abstract: A pair of pumps driven by a common motor draw in ambient seawater through e and expel it through the other to following electronic instrumentation. Coupled between the pumps, a rapidly rotating disk receives the flow of seawater and radially dissipates it in a multitude of separated droplets. The droplets are collected in a reservoir and the second pump expels it to the instrumentation. Where the flowing seawater is separated into droplets by the rapidly spinning disk, a break is created in the electrical conductivity continuity so that the following electronic instrumentation is not influenced by possible electrical potentials in the ambient seawater.

Abstract: Method and apparatus for laying an oil filled, electric cable at great depths and under conditions whereby the weight of the oil may cause internal cable pressures which will rupture the cable. In the method, the leading cable end is fed over a guide which is higher than the point at which the weight of the oil column between the guide and the cable source is equal to the normal oil pressure in the cable and is then fed downwardly but without exceeding an amount which would cause the oil column pressure after the guide to exceed safe limits for the cable. The pressure on the oil at the cable source is then reduced producing a torricellian vacuum in the cable at or near the guide which is maintained at a value such that the weight of the oil in the vertical section of the cable does not exceed safe limits. The apparatus includes the guide and pressure regulating and indicating devices at the cable oil source and the leading end of the cable.
