The cable industry does not stand still and is constantly developing. New materials, new types of cables and cable products, new methods of design and calculation are emerging. However, some things in the cable industry remain unchanged from year to year – we are talking about cable drums (reels). All over the world, in the
When applying insulation, it is necessary to keep the high voltage cable in an upright position for a certain time to avoid ovalization and other negative effects. If we know the recommended time, then we understand that the required height of the extrusion tower will be proportional to the desired cable production speed. Hence the
For cables there are many reasons for water penetration and growing of water trees inside the insulation. For example, it could be: 1️⃣ Production:👉 the raw materials used were not dried;👉 on the extrusion line (application of insulation or polymer sheath), when starting a new order or completing it, the water level in the cooling
We all see here on the Internet (LinkedIn etc) the unspoken competition between different manufacturers of subsea cables. These companies build concrete towers in which the process of applying insulation to the cable core takes place. They always mention the height of the tower, and every new tower is more and more high. It looks
Some companies like to talk about successful projects, and we know that there are really a lot of such projects, and this is very important for our industry. However, successful projects do not teach us much, and, in fact, it is much more interesting to study the mistakes that were made during the realization of
The reliability of cable lines depends on a number of factors:1️⃣ Design (including calculations);2️⃣ Production and delivery;3️⃣ Cable laying and termination/joint installation;4️⃣ Cable operation (testing, monitoring, diagnostic etc);5️⃣ Unpredictable actions of third parties. Mistakes at any of these stages can lead to serious financial losses: damage to the cable, the need to repair the damaged
Books seriously explain to the readers where the root of three or the root of two are needed in the energy sector. I decided to write about “combination” of these roots – a cubic root of two. Let it be the “cable root”. Cable specialists know well where and why it is needed. This is
Sometimes it seems to me that the world has gone crazy. At such moments, I think – God, thank you that I have my specialty “power cables”, which on the one hand allows me to distract myself from sad thoughts, and on the other hand to do something really necessary and useful for society. Apparently,
Designing a cable line is an interesting process that resembles moving in a circle. The fact is that in order to select cables, we need the correct values of the short-circuit current (1.1) and the steady-state current (1.2). Such currents can only be calculated using information about the impedances of the cable line (R1, X1,
