摘要： In a gas insulated high voltage cable having an outer tubular, corrugated conductor and an inner centrally disposed conductor, a spacer construction for holding and spacing the inner conductor in the tubular outer conductor, wherein each spacer has at least two spacer elements of semi annular construction each and complementing each other for establishing a closed annulus, each element constructed for laterial slipping onto the inner conductor, and the two spacer elements are secured to each other to establish the closed annulus in positive disposition on the inner conductor. Additional features impede local voltage breakdown, positive interlock of parts and resilient load relief.

摘要： Defects in a cable are located by causing the defect to issue voltage pulses propagating in opposite directions; one pulse is reflected at one end and arrives at the other cable end later than the other pulse. The delay is indicative of the location of the defect and is ascertained by forming the auto-correlation function of a.c. signals which appear at that other cable end. For a phase setting of the auto-correlation function equal to that delay, the function has a pronounced peak. Calibration on the basis of correlating a stimulus with its reflection provides a maximum delay serving as a reference to locate defects by the auto-correlation method.

摘要： In the attachment of a tension rod to an open end of a cable, one end of a tension rod is axially inserted into the core of the cable and the combination vertically positioned with the other end of the tension rod extending downward. A heat shrinkable plastic cap including a casting resin is moved up from below the tension rod until the inside bottom surface of the plastic cap comes proximate to the bottom of the tension rod, and the upper open portion of the plastic cap encompasses a section of the cable jacket. Heat is then applied to the upper portion of the plastic cap so as to shrink the upper portion to form a hermetic seal with the cable jacket, and then to the lower portion of the plastic cap so as to shrink that portion of the plastic cap toward the portion of the tension rod extending from the open end of the cable, so as to form a closed volume within the cap that decreases upon shrinkage to uniformly press the casting resin contained therein into the cable core. At the interface of the plastic cap and the engaged portion of the cable jacket there is preferably provided a pressure resistent bonding material that improves the hermetic seal and minimizes any longitudinal slippage between the cable core and the cable jacket upon the application of a pulling force to the tension rod.

摘要： Copper tubing is drawn through a die by means of a rotating drum to which the front end of the tube is fastened and may remain fastened as the drawn tubing is coiled on the drum, or the front is released, so that frictional engagement of multiple coils on the drum provide for pulling. An annulus pushes the coils down, but is retracted or remains ineffective as long as the front end of the tube is fastened.

摘要： A composition for bonding to copper comprised of copolymers and ionic copolymers of ethylene and an .alpha.,.beta.-monoethylenically unsaturated carboxylic acid having incorporated therein a copper deactivating amount of a copper stabilizer or deactivator. The composition has improved moisture-resistant bond strength on copper and laminates of copper and the composition may be employed as a protective sheathing for cables.
