triple clamps

Bundling and fixing cables in a triangle

We know how difficult and time-consuming the assembly of triple clamps is. The three cables lie on the cable cup and now have to be lifted at the same time in order to push in the lower part of the clamp between the cup and the cable. Due to the height of the clamp lower part, the cable bundle then rises out of the cable cup and only comes to lie on the cup after a certain distance, unless the clamp support is structurally elaborately lowered.

One would also strive for the electrically ideal position, in the triangle in mutual contact.


It is a constructive task to find an easy-to-install construction so that the cables are bundled and fixed immediately after laying on the cable cup.

The first solution is a patented (Pat.No. AT 501445 A4 2012-04-15) Clamp with movable side parts, which press through the correct dimensioning of the angle bracket on the side of the two lower cable. This also sets the ideal electrical triangle system, which is not the case with conventional triple clamps.


This clamp has already been implemented in some systems, even with vertical cable routing.

Something disadvantageous turned out in practice that the cables can be fixed only when all three cables are laid. Furthermore, a prerequisite is that the clamp comes to lie on metallic surfaces or smooth concrete, on rough concrete the system does not work well with the movable side parts. Really ideally suited to mounting rails as shown in the pictures.


On request this triple clamp is available. There are versions for the DM range of 65-95mm as well as 77-95mm cable diameter as well as a version of 37-52mm for medium voltage cables.

A better and more robust solution is a structurally already finished, but not yet realized triple clamp: The assembly can be done after the installation of the second cable by the two cables pushed together with the side parts (screw clamp) and these are then fixed, the third Cable is then clamped down with the clamp.


With this arrangement, the type of cable support does not matter, because yes, the side panels do not have to "slip". On the mounting rail is possible as well as on the concrete floor in substation or in a concrete cable channel.
