In this article we show how the formula for $T'_4$ in IEC 60287-2-1 was derived from the early developments in the 1940's and 1950's to its current form.

When a cable heats up, it gets slightly longer. If the endpoints stay fixed, that extra length mostly turns into more droop (sag) and lower tension. Engineers estimate the added sag by using a...

In Cableizer the approximate temperature distribution can be calculated by using the superposition principle with image sources or the finite element method using Dirichlet boundary conditions for...

In this article various topics are discussed regarding cable pulling, specifically the usage of weight correction factors and sidewall bearing pressure factors for pulling up to 6 cables in a...

With the multi-layer backfill method, it is possible to simulate the filling of a rectangular trench where the cables are buried with two superimposed horizontal layers of different materials,...

Based on the example of a deeply buried tunnel, the effect of the deep burial thermal inertia advanced option on the cable ampacity is illustrated and validated.

When simulating objects that are buried deeper than a couple of metres one needs to consider the thermal inertia of the surrounding soil. Cableizer offers an alternative approach to calculate the...
