Hi Erik E

Any news of the start of the thread on equipment? :D
Probably wise to make it a sticky?

Hi,

Hahah!

Fire at will, and I will answer (when I know the answer ofcourse)
Perhaps I will make some scans of original Dienstvorschriften!

Erik,

Perhaps it also wise not to mention the location of the devices because
of all the relic hunters. When the location are known the site will surely be stripped. :( :x

Kabelendeverschluß

Post by P. Heijkoop » 04 Oct 2004 19:15

Hi,

First picture. :lol:
With all the different sizes and extra's there were no less then 110 different version of this telephone connection box possible. The official
function of this box was
1) the connection of different ground cables (Festa; Festungsaußenkabel), or;
2) the connection of an earth cable with the internal telephone-system of cables (Festi; Festungsinnenkabel) of the bunker

another page, I just discovered a couple months ago, about atlantikwall in france, mostly bunker oriented:

for non-french speakers, there is a good section on bunkers and its parts:

home: http://site.voila.fr/bunkers

bunkers main (whitout frames): http://site.voila.fr/bunkers/bunk.htm

there the heading says: Typology/plans, bunker elements, construction assembly types, and construction categories,

the site is very extensive. I just surfed the bunker elements page, and is very detailed, it comprehends: (english translation follows original webpage title for you to surf easily)

Chauffage : heating
Camouflage : camouplage
Codification : nomenclature
Citerne : water storage
Défense d'accès :accesss defense, interior and exterior
Elements divers : miscelaneous alements
Front Todt :Todt shell deflector
Inscriptions . inscriptions (slogans, instructions, etc)
Orifice pour périscope : periscope holes
Plaques de blindage : armoured gun mounts
Portes : doors
Puits d'antenne : antenae mounts
Sortie de secours emergency exits (backdoors)
Téléphones : phone systems
Ventilation : filtration, ventilation

Very well detailed with pictures for references in most cases.

Hi,

Yes, and there are even more.
These Kabelendeverschluße are of the type 'Groß' or large. That has nothing to do with the physical size, but with the kabel sort of connection points on top of the KEV. The KEV Groß has large 'Kabelklemmendurchfuehrungen' with alluminium srews to connect e.g. a telephone. These Durchführungen are covered by alluminium lids. You can see this cleary on picture el5.JPG and el1.jpg

The KEV klein, doesn't have these large 'Kabelklemmendurchfuehrungen', but only has one or simple holes on top. You can see this on the attached picture.
Of the KEV Klein there were also 100 different versions. So in total there were no less that 210 different KEV versions possible, differing in the number and type of cables entering the box and thus the size of the box. For each KEV-type (Groß & Klein) there were 5 different sizes. Of the KEV Groß there were versions with 8 (the smalles) up to 100 cablepairs going in the box. The KEV-Klein was limited to 60 pairs.

The interesting part here is that you see three of the main
factories who build the communication equipment. Siemens & Halske, AEG and Felten & guilleaume Carlswerk AG
Other factories were TN (Telefonbau u. Normalzeit), DeTeWe and Wilheml Quante.

The boxes on the left side of the picture El8.JPG
are norwegian adapted, that is the piping on top is not original. On the same picture on the right are the normal 'Kabelklemmendurchfuehrungen'

Hello all

Erik - When i was in the Army back in 1975 - 1981, i was in a Panzer Infantery regiment. We used to lay fieldcables out in the "frontline"
to listen in on "enemy" radiocommunications.
The cable was laid in different lenght, responding to different frequenses, being able to locate which frequency the opposition used.

Could it be something like that - the cables in the bunker above ??

Regards
Kurt

el6.JPG


El11.JPG:
A KEV Gross with 5 kabel-entries and 5 Kabelklemmdurchfuehrungen on top.
El10.JPG
A KEV (Klein) with 6! kable-entries (largest size) and probably (can't see it good) 4 small openings on top

el6.JPG is a Kabelanschlußstelle for 1 or 2 cable pairs. This is NOT a KEV, not even a small version. It's a very different type of box. This was used to connect field cables (so not the ground cables, but the ones on poles and the loose ones) or mobile installations (e.g. fieldtelephones) on the system of the bunker or (when connected through) to the Festungskabelnetz.

In total four types were used:

Kabelanschlußstelle 1-paarig or 2-paarig (1-2 cable pairs)
Kabelanschlußstelle 6-paarig (3-6 cable pairs)
Kabelanschlußstelle 10-paarig (< 10 cable pairs)

These boxes were usually montaged in the niches in the entrance. There you see that a bunker with a shelter or combat function, such as a 622, 630 etc. were usually equiped with a Kabelanschlußstelle for 1 or two cable pairs. Most artillerie-observationbunkers I have seen (such as 143, 120, 613) were equiped with a 6-parige. Commandposts (610, 608, 117) are usually equiped with Kabelanschlußstelle 10-paarig, as are the communicationbunkers, such as 616, 617 and 618

Futhermore I have seen installations in Denmark and Norway (mostly in R 636) were they used Kabelanschlußstelle 10-paarig to connect the main switchboard of the bunker (probably a field version) to the Hauptverteiler.

regarding the 117.
Do you know to were the cable runs?
To the antenna-plugs in the entrance or a Kabelanschlußstelle?

Normally you see that the Germans used an extra turn in a cable of about 50cm before entering the cable from the Funkaußenanschlußdose to the Funkinnenanschlußdose

Hm.... Impressive!!
Had no idea that there were so much different stuff for the same purpose.

As far as I remember, the cable goes to the antennaplugs, but why??
Something to do with resistance??

More stuff:
