GUt DE T O USE

This "Guide to им* It applicable to cablet according to Section C of Part 5 of HD 604,

2. Object

The object of this ‘Guide to use" іб to provide recommendation* for the cables specified in Section C of Part 5 of HD 604 .

3. Recommendations for use

3-1 Permissible application

Cables may be instated indoors and outdoors for fixed installations on walls and mecaibc structures. They may not bo installed in waterlogged conditions without reference to the manufacturer,

4. Recommendations for storage, transport and handling

4 J Delivery

When deKvered on a drum the core diameter of the drum shaM not be less than;

- 14 timet the outer diameter of the cable for unarmoured, braided and double screened cables-

• 16 times the outer diameter of the cable for cables with helically applied srmour/PE conductor. The distance between the outer cable layer and the head of the drum flange shall be sufficiently high to avoid damages to the cable.

Short cable lengths may be coiled to rings and transported and stored horizontaly. The bending radii shaN not be less than the above mentioned values,

4.2 CabC »rxJ taaiinc

The cable ends shall be sealed waterproof during transports storage and laying.

4.3 Transport

For the transport of filled up cable reels only suitable carriers shaB be used. Cables stored at room temperatures which fall below those recommended for installation shall not be subject to any mechanical stress including shocks, impact, bending and torsion. It shall be prevented that drum flanges come in touch with the cable of another drum. For loading and unloading of cable drums sortable lifting and hoisting equipment shall be used; never drop a drum on the ground or on a buffer.

See also relevant figures.

Filled-up cable-drums shall be roHed only short distances over plain solid ground in the direction indicated. The cable end shall be tightened»

4 4 Lowest tamoerature for саЫе lavino and mstallahon

Lowest temperature of cable during installation is 0°C under normal conditions of tare.

Thia temperature is valid tor the cable itself and not for the environment if possible die temperature of the cable shall be raised to at least + 10°C before laying, e.g. in a heated building, to facilitate handling and to reduce the risk for damages.

4.Б Pulling loads

ft is assumed that the cable route is well designed for the laying procedure with wen estabfished curves and a sufficient number of cable rollers. Special attention shall be paid to the required minimum bending radii (sea sub-clausa 3.6). The pulling forces shall be permanently supervised during the pull-in procedure<

The pulling force shall be evenly divided over the mam conductors^

The maximum pulling force IPI shal be calculated as follows: P - Str where P is in N о is maximum tensile stress <i conductor, viz, 50 Н/тгл* for copper conductor.

30 M/mm* for aluminium conductors.

S is total cross-sectional area in mm* of the main conductors {ignoring screens, concentric conductors and auxiliary conductors).

In die case of using a cable stocking, the total pulling force shai not exceed 1000N.

4.6 Bendina radius

During ins tala t ion the internal bending radius of the cable shall not be smaller than 10D_f where D it the overal diameter of the cable. This value may be reduced to 8D in case of a careful, one single time bending of the cable end.

Bending nearby the temperature limits given in sub-clause 3.4 should be carried out extra carefuly*

5. AHnourad single пив catrtas

Single core cables with arrnour/PE conductor made up partly of steel wires are for direct current only.

e. Current rating

For the calculation of the continuous current rating, see IEC 287.STORAGE

Keep the drum standing upright, using wedges in the heels of the flanges

TRANSPORT

Drums may only be piled flange on flange. Lower layer to be secured over full drum width.

Never lay them fla

t

Drums may be lifted either by crane or fork-lift truck

SECTION D

1. SifiM

Thia section specifies requirements for and dimensions of single core and muhicoce cables constructed whh halogen-free materials having reduced fire propagation performance.

The cables considered are intended for им where the combination of ambient temperature and temperature rise due to loading current results in a temperature not exceeding 70*C in steady state conditions and 160°C during short-circuit.

This section covers the following classes of cables:

IO One io five core cables having copper conductors and a metallic covering-

(111 One to five core cable & having aluminium conductors and a meta Be covering.
