2. Object

The object of this document t£ to provide recommendations for the selection, storage, disposal, vansportatioD end installation of the cables specified under Clause 1.

3. Recommendations for lm

   1. Permtssible application

These cables may be installed indoors and outdoors for fixed installations on waMs and metallic structures. These cables shall not be installed where the emission of corrosive fumes and excessive smoke in the event of a fire are forbidden.

These cables may be used on Category А, В & C of ICC 1$3-

4. Recommendations for sttxaoe. transport and disposal

   1. Storage

Cable drums should be regularly inspected to assess their physical condition,

Battens, when suppied. should not be removed until a cable ts required for installations,

Cable drums having a flange diameter exceeding 1m and weighing more than 250kg gross shall be transported in an upright condition The drums should be protected against movement Loading and unloading shall be facilitated by sixtable devices to avoid damage to both cable end drum. When moving drums, due regard must be paid to the weight, method end direction of rolling, protruding nails and wood splinters.

Small quantities of timber or battens which may have been treated with wood preservatives may be burnt under carefully controlled condrtkma in the open. Cables shall only be inckierawd under the supervision of a licensed contractor.

Both ends of every length of cable shall be sealed in such a manner as to include the oversheath and to inhibit the ingress of moisture during storage» delivery and up to the time of jointing.

5. R»commer>datK>ns for cable layirx; and instaRation

s i Saoara!

Th* choice ol cable shaft lake into account the cable route, method of faying and sarv»ce condition*. The letter shall induda:

Ui The adjacency of other cables and their mutual heating effect; the specific earth resistivity, protection against egiar radiation; the earth loop impedance; the capability of the cable to withstand the worst anticipated fauh conditions of the system.

(b) The leakage of stray currents and attack from solvent substances.

(cl Soil subsidence and other forms of violent vibrations.

(d) Protection against mechanical damage during and after installation,

(el When cable are laid in ducts» the correct site of duct shall be used to avo»d damage during

installation and overheating,

(f) Where cables are laid In surface troughs, there shall be adequate ventilation which, however, will not permit the entry of debris

Cg> The cable support system should be designed to avoid damage or danger under normal fault conditions.

5.2 Environmental сотским

laj The lowest recommended temporalures for installation shall be O’C but care should be taken

to ensure that the саЫе temperature has been above 0^DC for the preceding 24 hours,

(Ы Loaded cables, especially single core cables, may have surface temperatures which reflutft protection against accidental contact.

53 Pulling tensions

The maximum pulling load shall not exceed the following values:

For copper conductors 50 N/mrn² of CSA

For aluminium conductors 30 N/mm^J of CSA

CSA refers only to the conductor!*).

Where long lengths of cable are to be pulled along difficult routes, where tension increases sharply due to bends, cogntrance shall be taken of the values for maximum s*de wall pressixe {Tension divided by Bencbng Radius! recommended by ibe supplier.

5,4 Bendmo radii

During installation, no cable shall be bent to a smaller radius than those hated below;

(al Armoured circular copper conductor 6 x D

• Tabulated overall diameter

5-5 Cable installation

(al There shall be a significant measure of compatibility between the way in which cables are inMaUed the test for fire propagation and the actual install lions.

(bl There shall be compatibilrty between all jointing materials and components of the cable.

tc) AM bonds for earthing chai nave adequate conductance, be as short and ее straight as

possible and be protected against corrosion, especially where dissimilar metals are involved.

6. T«u »h»r kistallatron

These are not mandatory, but when required shad consist of>

(a) DC test jfl-CaMfla

3500 V between each conductor and between each conductor and metallic covering. The vohage shaN be maintained for 15 minutes. Repeated de voltage tasting may damage the insulation.

lb) Test on PVC overtbeath

Where an outer conductive layer is applied to the overshsath. a de voltage of 3 kV shall be applied between the underlying armour and the outer conductive layer
