Version 3.3 rolling stock DEF25 15/01/02 11:42 Page 2

Traditional rolling stock

is being replaced everywhere.

High-speed services are

booming in Japan and

Europe. International freight

is increasing 25% yearly.

The European railroad supply

industry now has a 60%

share of the world market.

Its annual sales are

approximately $16 billion,

and its order books are full.

With the global market in rail

systems growing by 5%-6%

a year, competition is fierce

in the industry.

for susta inab le mob i l i ty and pro f i ts !


In this new rail era,

marked by liberalization

and privatization, increased

profitability has been

a growing concern. Since

rolling stock is a long-term,

strategic investment, both

manufacturers and operators

are demanding far more

from cable suppliers.

To move ahead manufacturers and operators must:

• Find expert partners to co-design and manufacture complete

cabling systems

• Intensify R&D to develop light-weight, adaptable, modular

solutions

• Incorporate IT cabling to maximize rail’s reliability, safety and

comfort

• Install common, interoperable systems to meet international

standards

• Ensure public safety and protection of equipment through

fire-safe cabling

• Cut costs through cable durability, easy retrofitting, and low

maintenance


Experts predict that

in 10 years, rolling stock

must be 50% cheaper

to buy and maintain,

and achieve 30% energy

savings.

Nexans expertise in

cables and components

can help you achieve

this goal.

Nexans produces a full range

of data and energy cables

and components found in

modern rolling stock, from

thinwall technique up to

45kV. Our catalogue includes

both standard and thinwall

control cables with or without

shielding; databus cables;

UIC cables; optical fiber

cables; special power cables;

sheathed singlecore and

multicore cables; high-

voltage cables and systems;

complete harnesses with

their connections and sealing

ends; robust jumper cables

for carrying control and power

functions between cars.

High-temperature

power cables for

locomotives and drives

To deal with extreme

temperatures and weight

constraints (especially for

ultra high-speed trains),

Nexans has developed a new

generation of compact silicon

cables which can operate

in temperatures of up to

140°C (tested to 180°C).

• Used on France’s highly

successful TGV trains, our

cables have been able to

achieve 10% to 20% weight

reduction for the 2 tons of

cabling which are standard

for this type of locomotive.

Rolling stock

power cables

Nexans provides a wide

range of flexible,

Class 5, tinned copper

monoconductors to meet

the power needs of today’s

locomotives and drives.

This includes cables that

can handle 3-phase drives,

with variable frequency.

• To assure protection

in the special operating

environments of both electric

and diesel locomotives,

Nexans has developed a

special polyolefin coating

against mineral oil in electric

motors and a non-halogen-

free CSP coating against

diesel fuel.

HV connection cables,

bushings, connectors

To carry electricity from the

roof-mounted pantograph

to the locomotive’s

transformer, Nexans

manufactures flexible high-

voltage cables (up to 25kV)

which are sold as a pre-

mounted, pre-tested set,

with bushings and connectors.

For years now, these sets

have been highly rated by

manufacturers like ADtranz.

• Nexans’ 700 series

connectors, extensively

used on trains in Europe,

China and Australia,

are now used by British Rail

on their locomotives.

They are known to be light,

compact, vibration-proof

and extremely safe,

with a 25 year life-span.

Standard and

thin-walled, control

cables - Flamex Wires

Nexans’ wide range of

control cables (with or without

shielding) provide energy

for communications, public

address, automatic doors,

lighting, etc. Where space is

limited, our thin-walled

designs have a tough but

flexible high-tech coating.

• Our clients are the who’s

who of the rolling stock

business, including major

constructors like ADtranz,

Alstom, Bombardier

and Siemens, in addition

to numerous cable

manufacturers serving the

railboard industry.

T h e re’s no one l i ke for keep ing you on the fast tra c k .


Databus cables -

Flamex Twinas

To assure surveillance and

a video liaison between

both extremities of a train,

Nexans has developed

a copper, twisted-pair data

cable which is made

to the highest standards of

guaranteed impedance.

• Polyethylene foam

insulation guarantees low

attenuation, while precise

manufacturing keeps

impedance at constant levels.

Like all other cables,

it is halogen-free (“0”ZH)

for reasons of public safety.

Coaxial cables -

Flamex RG and KX

Also for video connections,

we have developed a

special twinax coaxial cable,

which combines two cores

(copper with a tin coating)

within a flexible dielectric

coating, a shield and a jacket

(to guarantee impedance).

• Nexans coaxial cables

come in various sizes and

scopes of attenuation,

and have special sheathings

for safety, flexibility and

crush resistance, making

them both easy-to-install

and durable.


Optical fiber cables

Instead of a twisted-pair bus

cable, rolling-stock

manufacturers can use our

high-performance multimode

optical fiber cable to carry

vital onboard data.

• In the long term,

optical fiber offers many

important advantages,

including no electromagnetic

contamination (EMC), very

high data speeds, excellent

attenuation, compactness

and low weight in a confined

environment.

Harnesses

Rolling stock harnesses

consolidate wires, connectors

and identitification systems

not only in the locomotive,

but in drives and blak boxes

throughout the train. Nexans

designs, manufactures,

pre-mounts and end-tests a

complete family of harnesses.

• For the high-speed,

multifunction German

BR 101 locomotive, Nexans

worked closely with ADtranz

to custom-design a complete

system of cables and

harnesses which greatly

simplified end assembly.

Jumper cables -

Flamex M6 Jumper

Short jumper cables between

cars carry information

and energy in an open,

moving environment. Nexans

jumpers use a special

construction and materials

for high flexibility, strength

and durability.

• Nexans jumper cables

have won acceptance

worldwide. They are used

on all Alstom rolling stock

and are especially

appreciated for ultra-speed

trains in France, South

Korea, Spain, etc.

Winding wires for

traction transformers

Continuously Transposed

Cables (CTC) made of

multiple enamelled copper

conductors (class 180/200)

or impregnated glass fiber

yarn/glass polyester-blended

yarn copper conductors. In

addition, the cable (including

single copper conductors)

can be insulated with

stabilized cellulose paper and

polyaramide aromatic paper.

• Our plant in Arolsen,

Germany, specializes

in enamelled wire which is

used by major rolling stock

manufacturers, including

ABB, Alstom, Siemens, etc.

for onboard re l i a b i l i ty, safe ty and comfort .


Winding wires

for traction motors

Copper conductors

insulated with polyimide foil

(temperature class 240),

or impregnated glass fiber

yarn/glass polyester-blended

yarn (temperature class

155 to 200), and enamelled

(temperature class 180

to 220).

All our cables are

halogen-free (“0” ZH)

To protect people and

equipment, Nexans rolling-

stock cables are halogen-

free. This means that they are

flame and fire-retardant,

emit low smoke and toxicity,

and are non-corrosive in

the event of fire.

• With Cenelec

(the European Electrical

Board/working group 12),

which specifies new

standards for rolling stock

cables and their properties,

Nexans has been deeply

involved in developing and

testing new materials

and designs to optimize

safety at every level.


Nexans is committed

to co-operation at

all levels, especially with

a chosen group of

co-suppliers. We want

to share information,

pass on expertise,

and transfer technology

wherever possible.

Partnership

We are adept at working

with a group of suppliers,

including electrical drive

system and equipment

manufacturers, to develop

a new generation of efficient,

light-weight, modular

trains, thus reducing costs

and the number of vehicle

designs.

Integration

Wherever possible,

we integrate designs and

develop new interfaces

both to make installation

easier in end-assembly,

but also to facilitate control

and maintenance procedures

when the vehicles are in

operation.

Interoperability

To assure interoperability

in equipment specifications

and safety standards,

we have worked closely with

regulatory committees to

assure both modularity and

open standards. Our cables

are designed to fit into

rolling stock worldwide.

i s a junction for service and support .


Security

Our halogen-free (or

0-halogen) special cables

cover virtually every rolling

stock application; while

our data cables are ideal

for monitoring components,

advanced fault diagnosis

and data logging, so as to

pre-empt failures before

they occur.

R&D

As IT moves onboard

for intelligent suspension,

fault detection, control,

maintenance and

communications, we are

developing new integrated

data/energy systems to help

drive down costs and

maximize environmental

benefits of rail.

Product support

Manufacturing in more

than 20 countries

and operating in more than

60 countries, we are

committed to delivering what

you need where you need it.

Our “no-maintenance”

policy means that there should

be nothing to do between

major overhauls, apart

from replacing components

subject to wear.


In the rolling stock business,

the technology of steel-on-

steel, driven by electric or

diesel motors, will not change

in the near future. However,

trains will have to be cheaper

to buy and operate, with new

levels of safety, comfort, and

environmental-friendliness.

Much of this will be achieved

by technological advances:

intelligent suspension,

more efficient motors and

transformers, composite

bodyshells, lighter electronic

equipment and cabling, and

IT-based onboard devices.

Experts say that in 10 years

time, electrical equipment

will have to weigh a quarter

of today’s, and be equally

reduced in size.
