GUIDE TO USE

1. Sfififcfi

Thia Guide to Use is valid for th* application of 0.6/1 kV PVC-insulated and PVC-thaathod tingle and multicore cable* with special fire performance properties, mainly intended for use In power plants and substations >

2. Object

The object of this document is to provide recommendations for the selection, storage, transportation and installation of the cabtea, specified under item 1, Scope,

Note 1: Safety requirements as well as rules of ins tai at ion are not considered in this Guido to Use. as they are covered by other relevant regulations and laws.

Note 2: Cable* in this part contain PVC. and when exposed to the effects oi hr* will produce harmful smoke and fumes. The by-products of burning scrap cable can be a health hazard. Incineration should only be undertaken by a licensed contractor.

3. Recommendations for use

   1. Permissible applications

Specified cables according to HD 604 Part 3 Section A may be used indoors, also in wet locations, and outdoors for fixed installations on walls and metallic structures. Direct burial in sol is allowed, as long a* the relevant rules of imtalation are followed.

Cables rated at LtoAJ- 0.6/1 kV may be used in DC system* having a rated operation voltage between conductors nor higher than 1.5 kV, and between conductor* and earth not higher than 0.9 kV.

The concentric conductor may be used as neutral, PE-conductor, PEN-conductor or as a screen, In accordance with relevant regulation*.

4. RacommendatKyA for storage and transport

   1. Delivery

The distance between the outer cable layer of a fiHed-up саЫе-defivory-drurri and the head of the flange shall be sufficiently high to avoid damage* of the cable.

The cable ends have to be sealed waterproof during transport, storage and laying.

Cable drums with flange diameters exceeding 1 m have to be transported with the drum axis in horizontal position. The drums have to be protected against movement Loading and unloading shall ba mads by suitable devices to avoid damage of the cables and of the cable drums

FiMednjp cable drums shall be roMed only on short distances over ptam solid ground in the direction indicated on the cable drum, The cable ends have to bo tightened.

Б. R acorn me ndation fof cable laving and installation

In this context the following items shall be taken into account:

a) The service conditions, like concentrations of cable quantities, influence of external heat, specific aanh resistance, protection against solar radiation, which form the basis for the selection of the cable type.

bl Leakage or stray currents and corrosion.

c) Movements of soM, vibrations (foundations ot machines, bridges! shakes.

di The method of laying and the bedding material have to be selected in respect of the outer cable sheath to avoid mechanical damages.

al Protection against outer influence, e.g. chemical solvents.

Cables laid in ground are considered as being sufficiently mechanically protected, if the relevant regulations and laws concerning laying depth in ground and protection are followed.

The laying depth in the ground shall tn according to the relevant regulations and laws.

In case of several cables within one pipe the diameter of the pipe has to be so wide that the cables do not block themselves.

If it it planned to lav single core cables of a throe-phase-system through steel pipes, all cables belonging to the same system have to pass through the same pipe.

It is recommended to protect the pipe against chocking with sand

The lowest allowed temperature of the cables during installation and mounting of accessorial ia:

O^C for PVC or XLPE insulated and PVC sheathed cables according to HD 604 Part 3 Section A.

The temperature is valid for the cable itself and not lor the surroundings. If the cable does have a lower temperature than permuted _t h must be heated up.

Cere has to be taken that the temperature remains above the lowest permitted during the whole laying operation.

5 ,3.1 For pulling in of cables by means of a pulling-head at the conductors, the foMowing maximum values for the puling forces ere allowed:

a* For cables with copper conductors 4-50 N/mm¹

bl For cables with aluminium conductors 4 - 25 Nrtnm³

c) The maximum pulling force for all cables must not exceed 20,000 N

With these puling forces it is guaranteed that the permitted elongation of 0.2% for rhe conductor wiR not ba exceeded. The maximum pUkng ftxce [PI й calculated from the total of the CSA tSk The CSA of the screens and of the concentric conductors shall not be considered in this calculation.
