Key Features – Down Conductor Cable
- High Conductivity: Made from pure copper or aluminum for efficient current flow.
- Lightning Protection Essential: Safely channels lightning energy from air terminal to earth.
- Corrosion Resistant: Withstands harsh weather and environmental conditions.
- Flexible Installation: Available in multiple sizes and stranded or solid forms.
- Standards Compliant: Meets national and international lightning protection standards.
- Durable Build: Offers long-lasting performance and minimal maintenance.
Setting Up and Measuring:
One essential component of a lightning protection system that must adhere to tight regulations is the placement of down conductors.
- Sizing: The class of the LPS, which is based on a risk assessment, determines the conductor’s size (cross-sectional area). Minimum sizes for various materials are specified by international standards to guarantee that they can withstand the possible lightning current without suffering damage. For instance, a copper conductor typically has a minimum cross-section of 50 mm².
- Spacing: A structure usually has several down conductors installed on it, spaced out around the perimeter at predetermined intervals. The LPS class determines the spacing distance (10m to 20m for higher levels of protection, for example). In general, each structure must have at least two down conductors.
- Placement: Down conductors should be routed as straight as possible and are placed on the outside of the structure, preferably at the exposed corners. Using specialized clamps, they should be firmly fastened to the structure at regular intervals (e.g., per meter).
- Connection: The down conductor needs to be connected to the earth termination system at the bottom and the air termination system at the top in a safe, low-resistance manner. To make disconnecting and testing the earth resistance simple, a control joint is frequently placed at the base. In order to shield the down conductor from mechanical harm, a protective tube is also positioned at ground level, up to a distance of two meters.
Applications of Down Conductor Cable
- Lightning Protection Systems in residential, commercial, and industrial buildings.
- Solar Power Plants for grounding solar arrays and lightning discharge.
- Telecommunication Towers to protect tall structures from lightning strikes.
- Oil & Gas Facilities requiring stringent lightning safety measures.
- Airports & Stadiums with high-exposure open areas.
- Data Centers for grounding critical electrical and communication infrastructure.
