5Introduction

Powerbar manufactures and provides a wide range of busbar systems from

160Amp to 6300 Amp.

Busbar systems have many advantages over wire and conduit installations.

Why Busbar and not Cable?

Lower Total Install cost

Busbar material costs are often equal or less than wire and conduit.

Lower life cycle costs

Busbar components can be added, deleted or relocated after the initial

installation due to to the simple jointing mechanism, saving time and money

Predicable Characteristics

Busbar systems conform to common international standard and are

tested to BS-EN 60439-1 & 2. Readily published characteristics on busbar

short circuit rating, voltage drops, weights and dimensions can be used.

6Technical Features

GeneralPowerbar compact sandwich construction made up of insulated epoxy resin coated conductors and aluminium housing can

be adapted to any building structure. All necessary components are manufactured within the factory. Special components

can be manufactured to match clients requirements.

ConnectionsInstallation of joints is simple and effective with the mono block jointing system. Belleville spring washers on both sides of the

joint maintain the correct pressure and ensure a more secure, reliable and maintenance free installation.

Heat TransferWhen it comes to temperature derating busbar trunking is clearly superior to cable. Even at modest ambient temperature

trunking typically needs to be derated 10% less than an equivalent cable. Powerbar busway has a modern totally enclosed

housing design requiring no derating regardless of mounting position. Because the housing has no ventilating holes, the entry of

dirt and possibility of accidental contact with bus barsis greatly reduced.

Powerbars High Powerbar(HPB) range is a

1000volt,totally encased, non ventilated, low

impedance sandwich construction, available in

with either copper or aluminium conductors. The

copper option is available from 1000A to 6600A

and the aluminium option is available from 1000A

to 5000A. The HPB range is available with a

choice of ingress protection from IP55 to IP67. the
