Abstract

The present publication relates to a power cable termination, wherein leakage current may flow through a cable termination part at a contaminant area. The cable jacket may be damaged by such a leakage current. A current collector is applied between the termination bottom and the cable jacket part. Now, the leakage current flows to ground through the current collector. As a result, damage of the cable jacket may be avoided.

Termination Surface Leakage Current Collector

The present publication relates to a power cable termination, wherein leakage current may flow through

a cable termination part at a contaminant area. The cable jacket may be damaged by such a leakage

current. A current collector is applied between the termination bottom and the cable jacket part. Now,

the leakage current flows to ground through the current collector. As a result, damage of the cable

jacket may be avoided.

As for the structure of the current collector, a copper wire is soldered with a metal foil tape that spreads

the adhesive material on one side, as shown in Fig. 1. The current collector is wrapped on the cable

jacket before the termination body is installed, and the termination body is installed afterwards.

The following effects are achieved by such a construction:

- It is possible to separate the termination surface leakage current and the cable charging current for cable degradation check.

- There is no concern of the current collector dropping off, because it is fixed to the cable jacket by the adhesive material.

- There is no concern of damaging the termination body with a sharp tool etc. during installation of the current collector part to the termination.

The installation of the current collector and the assembly of the termination body includes the following

steps:

1. Cable preparation: This work is similar to usual terminal processing. 2. Current collector installation: The liner in the metallic foil part of the leakage current clamping is
