Earting Wires

Un-sheathed copper wires in which copper is annealed with 99.99% purity and refers to class 2 (according to ISIRI 3084 standard).

The national standard for the production of this wire is ISIRI 3084, which is equivalent to the international standard IEC 60228.

If you need insulated Earthing wires, refer to the flexible and core wires page.

The most common use of the above wires is for Earth canals and Earth wells of buildings, offices, towers, industrial facilities, etc.

The specifications of un-sheathed copper wires (used in earthing) are as follows:

Instead of requesting earthing core with the above specifications, many customers use the specifications of hard aerial core to buy, while these cores are different in terms of structure, technical specifications and production standards.
