ТЫв Appendix covers the application of 0.6/1 kV cables according to HD 604 Pan 6, Section E.

2. Object

The object of thia document js to provide recommendations for the selection, storage, (SspoMl, transportation and installation of the cables specified under clause 1.

3. R«comnr»r*dationt for им

   1. PormiMibte application

Cables may be installed indoors and outdoors for fixed installations on walls and metallic structure*. They may not be installed in waterlogged conditions without reference to the manufacturer,

2. Maximum oarmiasible voltage

These cables may be used on Category А. В & C of IEC 183.

4. Becommendations for itorw, transport end disposal

   1. SiaraM

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

Battens, when supplied, should not be removed until cable fa required for installation.

2. Transport

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

3. Disposal bv indnentioq

Small quantities of umber or battens which may have been treated with wood preservative may ba burnt under carefully controKed conditions in the open.

1. 4. Cable end saalino

2. Both ends of every length of cable shall be sealed in such a manner as to mclude the oversheath and to inhibit the ingress of moisture during storage, delivery and up to the time of jointing-faqommendations for cable lavino and installation

   1. Gamrai

The choice of cable shatt take into account the cable route, method of laying and service conditions. The Latter shall include:

1. The adjacency of other cables and iheir mutual heating effect; the specific earth resistivity, protection against solar radiation; the earth loop Impedance; the capabMIty of the cable to withstand the worst anticipated fault conditions of the system.

2. The leakage of stray cur tents and attack from solvent substances.

Cel Soil subsidence and other forms of violent vibrations.

4. Protection against mechanical damage during and after installation,

5. When cables are laid in ducts, the correct size of duct shall be used to avoid damage during Installation and overheating,

6. Where cables are laid in surface troughs, there shall be adequate ventilation which, however, will not permit the entry of debris.

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