A Conductor constitutes to be the largest and the most important component of any earthing and structural lightning protection system.
RR offers an extensive range and variety of flat, circular and braided Conductors made from copper and aluminium confirming to European, British and various earthing and lightning protection standards. The Conductors are manufactured in our state-of-art production units with in-house automatic online tinning facility.
With highest regards to quality and with various certifications in place, we ensure that our Conductors used in earthing and structural lightning protection systems are capable to withstand severe climatic conditions with minimal and standard degeneration.
An efficient earthing system is achieved by using good quality Down Conductors with sufficient cross sectional area which enables it to carry the expected current flow.
Various aspects are to be considered while selecting a Down Conductor since they have to be resilient to the environmental conditions where they are used. The Conductor should be capable of withstanding mechanical damage and corrosion.
Copper Conductor Ratings
- Shown in the table below are fault current capacities, for one and three second durations, for a wide selection of standard sizes of copper tapes.
- These Conductor ratings are based on initial Conductor temperature of 30°C and maximum temperature of 250°C
