Busbar Trunking Systems is used for electricity distribution and is an alternative for cumbersome conventional cable systems. They offer the end user the following benefits:
- Lower risk of theft
- Busbar Trunking System has the advantage of expansions, changes, replacing and reusing capability in the future
- Loads can be fed from a Plug-in Box unlike with cables, where each floor/ machine is to be fed separately from the main switchboard
- Repositioning of distribution points is much simpler
- Installation time is much shorter then cable system. This provides low installation and manpower costs and help for better time management
- Busbar trunking systems have a modern and aesthetic look and can be used in open plan areas
- Busbar systems are maintenance free
- Close proximity of busbars reduces inductive reactance, resistance, impedance and voltage drop is much lower than with cable
- Specially designed housing act as a heat sink to yield improved thermal characteristic, high mechanical and short circuit strength
- Busbar Systems has no chimney effect, hence provide a better resistance to the spread of fire
- Automatic polarity is maintained during installation
- System can be mounted edgewise OR flat wise horizontally or vertically in any direction with all kinds of bends and tees etc.
- The compact structure and steel housing allows much lower electromagnetic field around bus bar system then cable
- Busbars do not generate electromagnetic interference on data system

Busbar Installations: Supply and installation of busbars
Busbar Installations is a company involved in the supply and installation of busbars. Busbar Installations’ range of cast resin feeder busbar has been designed to provide a low cost alternative to heavy LV distribution cabling in larger installations.
The cast resin trunking is suitable for use outdoors and for installations where corrosive products are manufactured.
The trunking offers a wide range of current ratings for horizontal or vertical mounting, feeding from transformers to switchboards, horizontal tap-off systems for high power distribution, and rising mains.
A cost saving advantage of encapsulated Busbar when used as a rising main is that there is no de-rating factor which has to be used in ventilated trunking to compensate for the “chimney effect”.
The standard installation offers a degree of enclosure IP 54 and by additional sealing of the joint area this can be improved to give a degree of enclosure to IP 66.
