Power shunts are large cross-sectional area copper braided connectors designed to meet the current carrying capacity of power distribution applications - designed with multi-layers of flat or round earth braids to achieve sizes up to 1000sqmm and carry currents in excess of 400 amps. Power shunts are used as an alternative to solid bus bars and power cable assemblies capable of carrying very high currents yet are flexible, robust and easy to install. Typical power shunt applications : power stations, transformers, motors, generators, switchgear, substations - low and high voltage. Power Shunts - Large Earth Braid Connectors T&D UK are established distributors of an extensive range of large braid connectors, also known as "Power Shunt" connectors with cross-sectional areas of up to 1000sqmm and current carrying capacities in excess of 1800amps - larger style earth braid power connectors are designed for heavy-duty power applications as flexible current carrying connectors requiring resistance to vibration. Robust, durable and flexible power shunt braided connectors are specified for power distribution in turbines, HV substations, power stations, distribution grids, electrified trains and rail systems as alternatives to solid bus bars.

Power Shunts
Power shunts are large cross-sectional area braided
connectors, customised and designed to meet
the increasing demands of power distribution
applications.
They are often designed with multi-layers of flat or
round braids to achieve sizes of up to 1000mm2 and
to carry currents in excess of 400 amps.
Used as an alternative to solid bus bars and power
cable assemblies, power shunts are capable of
carrying very high currents yet are flexible, robust,
easy to install and cost effective.

Note: Above current ratings are based on a temperature rise of 50˚C above ambient.
The current rating values are based on a simple flat braid configuration. The actual current rating of a power shunt will vary according to the
design and layout of the final braid configuration. It is recommended that each power shunt be tested and evaluated fully to ascertain its
suitability to meet the requirements of its final application.
