ROUND CONDUCTOR RD 8 FT

Round Conductor RD 8-FT
NOTE! THE PRODUCT DIMENSIONS ARE 125m FOR THE REEL OUTER DIMENSIONS AND WEIGHT.

This product complies with Standard SFS-EN 62305 and is intended for implementation of external lightning protection in fixed structures when environmental conditions or other reasons prevent the use of RD8-ALU-T conductor.
If the total length of the conductor exceeds 20m on the roof or wall, it must be equipped with an expansion joint to prevent damage caused by thermal expansion.

For grounding, use RD 10 buried steel; 10 mm diameter, 78mm² cross-sectional area.
The grounding system is part of the external lightning protection that conducts the lightning current to earth and distributes it there. The most important criteria for even distribution of the lightning current without generation of dangerous overvoltages are the shape and dimensions of the grounding electrode. Standard SFS-EN 62305-3 (IEC 62305-3) recommends as low a grounding resistance as possible < 10 ohms. The grounding system can be constructed in ways approved by the SFS 6000 standard. It is possible to connect different grounding systems and materials together, but potential corrosion risk (electrochemical corrosion) must be taken into account. Grounding systems must be connected to the structure's main equipotential bonding. This product description is an automated translation of the original Finnish description.
