 New And Old Cable Colour System

International Cable Colour System

For the purpose of standardizing technical requirements, the European Committee for Electrotechnical
Standardization ( CENELEC ) countries ( including Austria, Belgium, Czech Republic, Denmark, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain,
Sweden, Switzerland and United Kingdom ) have adopted the following colour code :

Systems Phase ( or Line ) Neutral Earth

1 - phase system Brown Blue Green/Yellow
L1 L2 L3
3 - phase system Blue Green/Yellow
Brown Black Grey

Change to Cable Colour Code / Sequence

Cable Type Old Cable Colour Code / Sequence New Cable Colour Code / Sequence
Single - core Red or Black Brown or Blue
Two - core Red, Black Brown, Blue
Three - core Red, Yellow, Blue Brown, Black, Grey
Four - core Red, Yellow, Blue, Black Brown, Black, Grey, Blue
Five - core Red, Yellow, Blue, Black, Green/Yellow Brown, Black, Grey, Blue, Green/Yellow

The existing cable colour code for fixed electrical wiring stipulated in the Singapore Standard CP5 : 1998 Code of
Practice for electrical installations has been amended to align with the new cable colour code in the international
standards such as BS 7671 and IEC 60446. A transition period of 24 months from 1 Mar 2009 to 28 Feb 2011 was
given before the new cable colour became mandatory on 1 Mar 2011.

With effect from 1 Mar 2011, all new electrical wiring shall comply with the new colour code. WILSON CABLES
will manufacture and supply cables with new cable colour code only. However, WILSON CABLES will continue to
provide the cables with old cable colour code to its customers based on request.

Note : Consultants / Customers shall specify their requirements of the cable colour code at the time of order.

IEC 60331-21 requirement.

Fire Alone Test : IEC 60331-21

The Fire Resistant Cable is subjected to the flame at least 750 °C

continuously for a period of 90 minutes or the specified application
time. Test voltage equal to the cable designated voltage is applied to
the cable continuously during the entire testing. After which the flame
shall be extinguished but the cable sample shall remain energised
for a further 15 minutes. During the test procedure the cable shall
maintain circuit integrity.

Flame Retardant Test ( Bunch ) : IEC 60332-3 Cat. A, B, C

A bunch of cables are installed vertically on the test ladder. A burner,

as specified in the test standard, is used as ignition source. The
flame is continuously applied for the test duration in the below table.
Flame is cut off after the test duration. After flame extinction, length
of charred portion is measured and should not exceed 2.5 meters
from the bottom edge of the burner.

4. Halogen Content & Corrosivity Test : WILSON CABLES provide LSOH type of cables with Low Smoke
IEC 60754-1 & IEC 60754-2 Halogen Free material, which comply with IEC 60754-1 & IEC 60754-2
( if applicable ) requirements.

Halogen Content Test : IEC 60754-1

Determine the amount of halogen acid gas, which is evolved during
the combustion of compounds based on halogenated polymers
and compounds containing halogenated additives taken from cable
constructions. The amount of halogen acid shall not exceed 0.5%.
Corrosivity Test : IEC 60754-2
Determine the degree of pH value and conductivity of the gases, which
is evolved during the combustion of compounds taken from cable
components. The weighted pH value should not be less than 4.3 and
the weighted value of conductivity should not exceed 10 μS/mm.

5. Smoke Density Test : WILSON CABLES LSOH type of cables with Low Smoke Halogen
IEC 61034-1 & IEC 61034-2 Free materials release very little smoke emission during a fire, which
are complying with IEC 61034-1 and IEC 61034-2 requirements, it
provide one more layer of safety protection to the personnel.

Smoke Density Test : IEC 61034-1 & IEC 61034-2

Burn the cable sample(s) in a test cube of 27 m³ volume, measure the

light transmittance of the smoke to determine the measurement of
the smoke density. The minimum value of 60% is adopted. Generally
the smoke density shall be followed the requirement specified in the
cable specification.

* “ Spaced “ means a clearance between adjacent surfaces of at least one cable diameter ( De ). Where the horizontal clearances between adjacent
cables exceeds 2 De, no correction factor need to be applied.

Notes :
1. The factors in the table are applicable to groups of cables of all one size. The value of current derived from application of the appropriate factors
is the maximum continuous current to be carried by any of the cables in the group.
2. If, due to known operating conditions, a cable is expected to carry not more than 30% of its grouped rating, it may be ignored for the purposes of
obtaining the rating factor for the rest of the group.
For example, a group of N loaded cables would normally require a group reduction factor of Cg applied to the tabulated It. However, if M cables in
the group carry loads which are not greater than 0.3 Cg It amperes the other cables can be sized by using the group rating factor corresponding
to ( N - M ) cables.

values need to be multiplied by the length of the run ( in meters ) and by the current ( in amps ) that the cables are to carry.

Voltage drop can be calculated using the following formulas :

Where
• V max = 4% x supply voltage ................................. ( 1 )
I = Current ( A )
Vmax x 1000
• Vd = ..................................... ( 2 ) L = Length of cable installed ( m )
I x L Vmax = Max. permissible volt drop in the circuit ( V )
• V ds ≤ Vd ........................................................................... ( 3 )
Vd = Max. volt drop in the circuit ( mV/A/m )
Vds x I x L
• Vt = ..................................... ( 4 ) Vds = Volt drop of the selected cable ( mV/A/m )
1000 Vt = Total volt drop in the circuit ( V )
Example :
Consider a route of 200 metres of cable to be laid direct in ground and to carry a 100 amp load, the supply voltage
being 415 V, three phase a.c. and the cable to be copper conductor, XLPE insulated armoured.

1. V max = Max. permissible volt drop in the circuit = 4% x 415 V = 16.6 V

x 1000
2. V d = Max. volt drop in the circuit = 16.6 = 0.83 mV/A/m

3. Select a cable from Table 17, such that the Vd s value is equal to, or less than Vd the 0.83 mV/A/m calculated,
at the same time ensuring that it will carry the current. It will be seen that this value ( Vds ) is 0.61 mV/A/m
giving a cable size of 70 mm 2
