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.

r

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

SECTION E

1. Зедов

This section specifies requirements for and dimensions of single core and mufti-core halogen'free cables with XLFE or HEPR insulation end halogen-free sheath having reduced fire propagation performance.

The cables considered are intended for им where the combination of ambient temperature and temperature rhe due to loading current results in a conductor temperature not exceeding 90°C. The maximum temperature for short<tfcuit condmon ie 250°С.

This section covers the following desses of cable:

Ш 2, 3 and 4 core cables having copper conductor and steel wire armour

tii) 2_t 3 and 4 core cables having sold aluminium conductors and steal wks armour

tiiti Single core cables having stranded copper, solid or sectoral aluminium conductors and ahjminkint wire armour

(rvf Mu№*core аихійагу cables having stranded copper conductors, and steel wire armour

2. Additional оикаі reouiremenp

Th* fo*owino 0*ner«l r*qui««mentt Sha* be read in conjunction with those given In parr 1.

The cores of all cables shall be Identified either by numbers or by colours In accordance with the following sequence:
