GUIDE TO USE

1. Scope

This "Guide to use" is applicable to cables according to Sector D of Pan 4 of HD 604.

2. Object

The object of this ’Guide to use" is to provide recommendations for the cables specified in Section D at Part 4 of HD 604..

3. ReeommandatHMis for storage, transport and tenJinfl

3-і РеНудгу

When delivered on a drum, the core diameter of the drum shall not be less than:

• 14 times the outer diameter of the cable for unarmoured, braided and double screened cables.

■ 16 times the outer diameter of the cable for cables with behcallv applied armour/PE conductor.

The distance between the outer cable lever 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 horizontally. The bending radii shal not be less than the above mentioned values.

The cable ends shall be sealed water-proof during transport, storage and laying.

For the transport of filled up cable reels, only suitable carriers shell be used.

Cables stored at temperatures which fal below those recommended for installation, shall not be subject to any mechanical stress including shocks, impact bendrig and torsion.

It shal be prevented that drum flanges come in touch with the cable Of another drum.

For loading and unloading of cable drums, suitable String 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 rolled only short distances over plain solid ground in the direction indicated.

The cable end shall be tightened.

Sheath of PVC ie liable to cracking at low temperatures in case of blows to the cable or excessive bending. Care should therefore be taken during transport, laying and installation. The lowest temperature for cables during installation is 0°C under normal conditions of care.

This temperature is valid for the cable itself and not for the environment- If possible, the temperature of the cable shall bo raised co at least +10°C before laying, e.g. in a heated building, to facilitate handling and to reduce the nsk of damage.

It is assumed chat the cable route is well designed for the laying procedure with well established curves and a sufficient number of cable rollers. Special attention shall be paid to the required minimum bending radii late Sub-clause 3.6b The puking forces shall be permanently supervised during the pull- in procedure.

The pul к ng force shall be evenly divided over the main conductors.

The maximum pulling force IP} shall be calculated as follows:

P - S о where P is in N v is maximum tensile stress in conductor, v>2 50 N/nwi³ for copper conductor 30 N/rnm¹ for aluminium conductors

S is total cross-sectional area in mm’ of the main conductors (ignoring screens, concentric conductors end auxiliary conductors).

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

ЗЛ Bendina radius

During instaNation, the Internal bending radius of the cable shall not be smaller than 10D_r where 0 is the overall 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 carefully.

4. Armoured single core cables

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

4. Current rating

For the calculation of the continuous current rating, see IEC 287«

STORAGE

Never lay

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

Drues say only be piled flange on flange. Lower layer to be secured over full drum width.

TRANSPORT

Roll the drum in the direction withwich it turned during cable reeling

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

SECTION E

1. Scope

This section specifies requirements for end dimensions of single core and multi-core XLPE or HEPR insulated and PVC sheathed cables having reduced fire propagation performance.

The cables considered are intended for use where the combination of ambient temperature and temperature rise due to loading current results in a conductor temperature not exceeding 90° C. The maximum temperature tgr short-circuit conditions is 250 °С.

This section covers the following classes of саЫе:

Пі 2j 3 and 4 core cables having copper conductor and steel wire armour

Ik) 3 and 4 core cables having solid aluminium conductors and aluminium wire or strip armour

(hi) Single core cables having copper conductor and aluminium wire armour

(rvj Single core cables having solid sectoral or stranded aluminium conductors and aluminium wire or strip armour.

tv| Multicore auxiliary cables having 2 up to 4B cores with copper conductors and steel wire armour

2 Additional gen*ml requirements
