Abstract
Abstract The invention relates to an outdoor sealing end ( 8 ) which is elevated on one side. Means ( 18 ) for fixing the cable ( 10 ) are designed on the base fittings ( 20 ). An electric duct ( 32 ) is situated inside the sealing end. Additional, conventional means for electrically connecting the cable shield to the earth potential and means for the field control (field control body 33 ) and the insulation on the inhomogeneous potential transitions on the cable end are provided. The electric duct ( 32 ) that is embodied as a pipe or pin is connected to the cable conductor ( 12 ) by means of contact elements ( 42 ). The duct ( 32 ), the insulating body ( 50 ) and the top fittings ( 70 ) form an assembly unit. The surface of the sealing end is coated with a voltage-dependent field-controlling layer ( 64 ).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
201 words
A cable terminator, in particular an outdoor terminator for an electrical cable having a cable conductor, comprising: cable insulation, a conductive layer and a cable shield, the terminator being mounted at one end on a base fitting and having means on the base fitting for fastening the cable, having an electrical duct in the interior of the terminator, having a top fitting for fastening an electrical conductor to the duct, having means for electrically connecting the cable shield to earth potential, having a field control device and a field insulating device, having an insulating body and having means for fastening the insulating body to the base fitting, the electrical duct being connected to the cable conductor via contact elements, wherein: the contact elements are designed as clamping elements, the insulating body is filled up with material from the region of the fastening means from the base fitting up to the level of the contact elements and wherein the filling is reduced towards the top fitting, such that an internal cavity is formed, and the insulating body is designed to take up mechanical load on the terminator, and wherein the surface of the insulating body is coated with a voltage-dependent field-controlling layer.
