• Design conditions for electrical cables:

o

Underground cable (buried)

40°C

o

In air

50°C

The LV cables for power distribution system and the loads shall be as follows:

• Cable shall comprise of plain copper, stranded circular conductors insulated with an adequate

thickness of extruded cross linked polyethylene (XLPE).

(4)

• Up to 10 Sqmm Cu/XPLE/PVC, unarmoured cable for indoor installations.

The cable sizing will be performed considering multi-core cables up to 240 mm

2

_{for distribution cables. For}

power, lighting and control cables the minimum cross section shall be 2.5 mm

2

_{. Maximum cross section for}

single-core cables shall be 630mm

2

_{. Single core cables may be used for practical and/or economic reasons,}

e.g., transformer secondary cables or in case of high current ratings where two parallel multicore cables of

the largest cross section permitted would not suffice. All three single core cables shall be laid in trefoil

formation.

Sizing of motor feeders and power feeders will be performed taken into account the Full Load Ampacity

Standard power factors and efficiencies at 90% load will be used in this calculation, in case of absence of

precise data.

provided with the concrete encasement for LV Cables at road crossings only. The LV Cables shall be laid at

a depth of 600mm as minimum.

In the Container Terminal-1 Area, all the ducts shall be installed with minimum ground cover of 900mm

otherwise it shall be concrete encased.

All LV cables in Buildings shall be installed on cable trays/ Trunking/ Conduits as per Specification section

21: Electrical Works Doc. No.: 9224-05-EL-SPC-7001 clause 9.3.3.

The correction factors / de-rating factors for the cables installed in Ducts and in Air are taken from “DOHA

CABLES” Catalogue.

4. CABLE SIZING CRITERIA

Sizing of LV cables will be based on the compliance of all of the following criteria:

• Voltage Drop

• Continuous Current Carrying Capacity (Ampacity)

• Thermal Short Circuit Capacity

(5)

4.1. VOLTAGE DROP

A feeder shall be sized in such a way that the maximum voltage drop over the cable ensures the proper

operation of the associated equipment in normal service. Excessive voltage drop will result in unsatisfactory

operation of electrical equipment, and represents energy wasted in the cabling system. Voltage drop can

also cause damage to electrical Equipment.

The following formula will determine the voltage drop:

• For feeders and motors under running conditions (three phases and single phase):

• For motors under starting conditions (three phases and single phase):

4.2. AMPACITY

The current carrying capacity of a cable corresponds to the maximum current that it can carry under

specified conditions without the conductor exceeding the permissible limit of steady state temperature for the

type of insulation concerned. De-rating or correction factors are applied where the installation conditions

differ from those for which values of current carrying capacity are defined. The following de-rating factors will

be applied depending on the type of installation.

The Voltage drop is measured from the LV terminal of the Transformer to the final load in a LV Circuit.

5.2. AMPACITY

Cable size will be selected in order to comply with ampacity criterion. The allowable cable ampacities for this

project are determined following the application of the appropriate correction/de-rating factors which are

applied where the installation and environmental conditions differ from those for which the values of current

carrying capacity are defined.

The following factors (de-rating and over-sizing factors) will be used in the calculation depending on the type

of installation:

6.3. THERMAL SHORT CIRCUIT CAPACITY

For incomer cables to all the switchgears the short circuit rating of the switchgear shall be used for the value

of short circuit current. The value for t has been taken as 1 sec for incomer circuit breakers.

According to the equation under paragraph 4.3 and taking into account the above clearance times, the

minimum conductor sizes shall be calculated.

The minimum calculated Short Circuit Ratings of conductor from “DOHA CABLES” manufacturer are

provided in the Appendix-11:

For switchgear outgoings (feeders and motor starters) the current limiting characteristic of the circuit breaker

has been taken into account in order to size the minimum cable sizes. For that purpose, let-through energy

curves of circuit breakers to be installed in the switchgear have been analysed.
