round up

Safe and efficient – diverse industries

Legrand Busbar Trunking Systems:

Low,

medium and high power busbars accom-

modate current and future planning of pow-

er distribution systems to meet the high

demands of modern installations and com-

plex requirements. Resin busbars, with an

IP68 index protection rating, are suitable

for high power outdoor projects.

Legrand cast resin transformers, with

low electromagnetic emission: Legrand’s

energy efficient cast resin transformers ef-

ficiently transfer electrical power between

two different voltage systems, at the same

frequency. These transformers have no risk

of insulating fluid losses and are a low fire

hazard − even in harsh environments.

XL³ cabinets and enclosures:

For sites

between 160 A and 6 300 A − provide solu-

tions adapted to meet exact site power

distribution needs in industrial, commercial

and residential environments. Most impor-

tantly, these units comply with every part

of the standard IEC 61439 to guarantee

reliability and total protection of the instal-

lation.

Uninterruptible power supply (UPS)

units:

The Legrand UPS system, which en-

sures continuity of service for installations

in diverse industries, provides reliable per-

formance in terms of power and back up

time.

Legrand’s power solutions ensure conti-

nuity of service and protection of electrical

equipment during planned and unexpected

power outages.

These modular systems include cast

resin transformers, with low electromag-

netic emission, busbar trunking systems,

enclosures for power switchgear and con-

trolgear assemblies, as well as uninterrupti-

ble power supply (UPS) units.

According to Legrand, the key advan-

tage in selecting these components for ef-

ficient, safe and flexible power distribution,

is the immediate integration between Leg-

rand’s busbar trunking systems, cast resin

transformers and XL³ cabinets.

All

Legrand

power solutions systems

encompass the latest technology for en-

ergy efficiency, quality power supply, opti-

mum safety and enhanced aesthetics.

Legrand’s busbar trunking systems (25

A – 6 300 A) which comply with internation-

al IEC 61439-6 standards, have minimum

overall dimensions and provide flexibility

in all areas of an installation, including con-

fined spaces. Resin busbars, with an IP68

index protection rating, are suitable for high

power outdoor projects.

Aluminium or copper busbars and cast

resin transformers are equipped with vari-

ous accessories to provide maximum ver-

satility for any type of power application, in-

cluding zones which are subjected to high

thermal stress and where equipment is

sensitive to electromagnetic interferences.

Safety is important in the design of all

Legrand components. The absence of fuel

masses in Legrand’s cast resin transform-

ers is combined with a low fire load typical

of busbars. This feature increases the in-

trinsic safety of a building against the prop-

agation of a possible fire. This fire retardant

range is tested for fire resistance according

to DIN 4102-09 and EN 1366-3 standards.

Switchgear for

Rosh Pinah

JB Switchgear Solutions

was recent-

ly awarded a contract by DRA Global,

for the design, manufacture and supply

of containerised motor control cen-

tres destined for an upgrade project at

Rosh Pinah Zinc in Namibia.

The multi-million Rand contract

includes JB Switchgear’s special-

ly-developed and compact ‘Eagle’

series container panel which allows

two rows of motor control on op-

posite sides of the container whilst

still maintaining the minimum meas-

urement of 1,2 metres (as specified

in the mines health and safety act)

between the opposing fronts of the

motor control centres. This design

holds certain advantage, i.e. space

saving, cost savings, and the benefit

of full functional testing before the

container substation is dispatched to

site. Busbars are easily accessible for

installation, maintenance and subse-

quent additions and/or modifications.

JB Switchgear’s ‘Eagle’ series

carries comprehensive type test cer-

tification, and has proven over many

years to be reliable, robust and us-

er-friendly. More than 31 000 (thirty

one thousand) tiers of this design

has been installed in various coun-

tries around the globe. The mining

sector into Africa is a very successful

deployment focus for containerised

substations, and is expected to grow

even further in the future.
