Persebaran Medan Listrik akibat Proses Exothermic Welding pada Kabel Tegangan Menengah 20 kV
In the 20 kV distribution system, insulated cables and conductors of fibrous and solid copper are used. Some problems on 20 kV system occur due to the line length of the lines. This obstacle occurs in the cable, mostly at the cable connection.

Let $L$ be a set of $n$ lines in $\reals^d$, for $d\ge 3$. A {\em joint} of $L$ is a point incident to at least $d$ lines of $L$, not all in a common hyperplane. Using a very simple algebraic proof technique, we show that the maximum possible number of joints of $L$ is $Θ(n^{d/(d-1)})$.
