Dubai. is. the. premier. cable. manufacturer. in. the. United. Arab. Emirates. and,. since. 1979,. has. been. meeting. the.

requirements. of. customers. throughout. the. Middle. and. Far. East. Ducabs. cables. are. used. by. some. of. the. most. .

demanding.utilities.in.the.world,.for.the.following.reasons:

Product QuitDucab.is. committed.to. supplying. its. customers. with. the. highest. quality. of. product. and. of. service. Ducabs. Power..

cables. have. been. type. approved. by. Lloyds. Register. of. the. UK. and. have. undergone.

rigorous.type.testing.by.BASEC.(British.Approvals.Service.for.Cables).They.fully.conform.

to.BS.6004.and.BS.5467.specifications.for.PVC.and.XLPE.insulated.cables.respectively,.for.

electricity.supply,.up.to.and.including.33kV.ratings.

In.addition,. Ducab.was. presented. with. the. Dubai. Quality.Award. 1994,.for. the. best. local.

CURRENT RaTINgS

Report.69-30.Part.5.which.is.based.upon.IEC.Publication.287.The.ratings.for.In.Air.installation.are.taken.from.IEE.Wiring.Regulations,.16th.Edition.

All.the.ratings.given.are.for.single.circuits.installed.thermally.independent.of.other.circuits.or.any.other.heat.source.and.

on.the.basis.of.the.standard.conditions.of.installation.given.in.relevant.Tables.between.18.to.34.For.other.ambient.or.

ground.temperatures,.depth.of.laying,.soil.thermal.resistivity,.the.rating.must.be.multiplied.by.relevant.rating.factors.in.

Tables.2.to.6.and.8.to.12.

It.should.be.noted.that.if.XLPE.insulated.cables,.are.subjected.to.operating.temperatures.appreciably.higher.than.the.

90C permissible for continuous operation, the insulation will undergo premature ageing thus affecting the normal lifeof the cable. However, limiting maximum conductor temperature to 105C during overloads with duration not exceeding4.hours.on.any.one.occasion,.or.a.maximum.of.100.hours.in.any.12.consecutive.months,.or.a.total.of.500.hours.in.the.

For.guidance.and.assistance,.given.below.are.some.of.the.IEE.Wiring.Regulations.requirements.for.cables:

Protection inst oerod current: (Cuse 433-01-01 o te 16t Edition o te

IEE Wirin Reutions)

This.states.the.requirements.which.effectively.determine.the.sustained.current.ratios.of.the.cable.viz:

(i).The.current.rating.of.the.cable.should.not.be.less.than.the.nominal.current.or.current.setting.of.the.device.providing.

protection.against.overload,.which.in.turn.should.be.not.less.than.the.circuit.current.

(ii).The.overload.protection.should.operate.at.not.more.than.145.times.the.current.rating.of.the.cable.

The.second.requirement.(ii).is.met.if.the.first.(i).is.met.when.the.protective.device.is.any.of.the.standard.fuses.or.MCBs.

mentioned.in.the.regulations,except.rewirable.types.of.fuse.to.BS.3036.

With.fuses.to.BS.3036.the.current.ratings.of.the.cable.should.not.be.less.than.138.times.the.fuse.rating.to.satisfy.(ii)

Protection inst sort circuit: (Cuse 434 o te 16t Edition o te IEE

Wirin Reutions)

The.cable.has.to. have.adequate.short-circuit.capacity.for.the.current.let.through.by.the.device.providing.short.circuit.protection.for.the.time.it.will.flow.

The.formula.in.Section.434-03-03.is.effectively.that.used.by.cable.makers.to.give.the.short-circuit.ratings.in.their.

publications.

If.the.device.providing.protection.against.short.circuit.is. the.same.as.that.providing.protection.against.overload.and,.

therefore,.has.a.rating.not.higher.than.the.rating.of.the.cables,.the.short.circuit.capacity.of.the.cable.will.automatically.

be.adequate,.there.is.no.need.to.check.

incompliance.with.Regulation.525.of.the.16th.Edition.of.the.IEE.Wiring.Regulations,.it.is.stipulated.that.the.voltage.drop.within.the.installation.does.not.exceed.a.value.appropriate.to.the.safe.functioning.of.the.associated.equipment.

(Note:.Diversity.can.be.taken.into.account.when.calculating.voltage.drop)

Since.the.actual.power.factor.of.the.load.is.often.not.known,.the.most.practical.approach.to.the.question.of.voltage.drop.

is.to.assume.the.worst.conditions.ie.where.the.phase.angle.of.the.load.is.equal.to.that.of.the.cable.The.voltage.drop.

range,.the. voltage.drop. deduced.from.the. tables.may. be.unduly.conservative.and. more.exact.methods.of. calculation.

The.values.of.voltage.drop.for.600/1000.V.rated.cables.are.given.in.the.current.rating.tables

In.those.cases.where.the.actual.current.differs.greatly.from.the.tabulated.current.rating,.the.results.obtained.from.the.
