GUIDE TO USE

1. Recommendation fgr.use

11. Permissible applications

Halogen-free cables may be laid in rooms and areas where dark smoke and oorroeive кігтдас can give damage In the case of a fire.

11. 2 Concentric conductor

The concentric conductor may be used as PE or PEN.

2. RecofnnMndabon ftx tNoarxi trantoort aod handlion of cabl> drums

The distance between the outer cable layer of fdied-up dekvery drum and the heed of the flange shal be sufficiently high to avoid damages of the cable. It shaM be prevented that drum flanges come in touch with the cable of another drum.

For the transport of filled-up drums only suitable carriers shall be used.

Cable drums wHh flange diameters exceeding Im have to be transported with the drum-axis in horizontal position. The drums have to be protected against movement. Loading and unloading shad be made by suitable devices to avoid damages of the cables and of the cable drums.

Fdlod-up cable drums shall be rolled only on short distances over plain, solid ground in the (Erection indicated. The drums shall be rolled in the same direction as it was turned during the cable reeling in (he manufacturing plant»

Cable ends shall be attached to the drum during transport, storage and laying.

2-1 Cable end sealing

The cable ends have to be sealed water-proof during transport storage and laying.

Race

tdation for cable installations

The cables shall be installed in such a way that the spread of fire end its consequences are limited. The relevant specifications especially those for preventive fire protection shal be taken into account.

For pulling In of cables by means of a pulkng-head at the conductors, the folowing maximum values for the pulling forces are allowed:

al For cables with copper conductors о ■ БО N/mm^a

ЬЗ For cables with aluminium conductors cr 30 N/mm*

With these puling forces it » guaranteed that the permitted ekxiQatkxi of 0.2% for the conductor will not be exceeded. The maximum puling force (И la calculated from the total of the CSA (SL The CSA of the screens and of the concentric conductors shall not be considered in this calculation.

P - Sa where PinN tn N/mm¹

S In mm*

The lowest allowed temperature of the cables during installation and mourning of accessories is:

-20 °С for cables with insulation and sheath of thermoplastic or cross-linked halogen-free polymeric compounds.

These temperatures are valid for the cable itself and not for the surrounding. In case cables do have a lower than the permrutd temperature they must be warmed up. Core has to bo taken that the temperature remains within the permitted range of temperature during the whole laying procedure.

During instahauon the bending radius shall not fai below the following values:

15 times the cable diameter for single core cables

12 times the cable diameter for multicore cables

In case of single time bending - for example in front of a terminal - it is permitted to reduce the bonding radius by 50%, provided the work ts made by ski led personnel, e.g., the cable ie heated up to 30°C, and the cable is bem by means of a template.SECTION Et CABLES WITH COPPER OR ALUMINIUM CONDUCTORS AND WIRE ARMOUR

One test should be carried out on each cable selectedtb) Corrosive sod gas test Uee 2Л.4.4)

At tbit it a test on a cable component end therefore generally independent of too or number of cores, only one test H necessary

3. Test for flame propagation of bunched cable (see 2.4.4.21

For compliance with the requirements of HD 605 clausa 4,1.4 two possible methods of installation are stated, Й, in spaced and in touching formations. One tut of mufti-core cable having a tabulated diameter not exceeding 16mm should therefore be selected and tested in touching formation and one having a tabulated cSameter between 26mm and 40mm (provided that at least two samples of cable ere used) and tested in spaced formation for compliance with the requirements Of HD 605 clausa 4,1,4*
