What governing standard and construction define CCS GROUNDING STRAND (Annealed Copper-Clad Steel (CCS) Concentric Stranded Earthing & Guy Conductor)?

CCS GROUNDING STRAND (Annealed Copper-Clad Steel (CCS) Concentric Stranded Earthing & Guy Conductor) is manufactured in accordance with ASTM B452 / ASTM B228 / IEEE 80 for Earthing / Bonding service over -50 °C to +200 °C. Its 2-layer construction comprises low-carbon steel metallurgical core, metallurgically bonded copper cladding (30%/40% iacs).

What is the minimum bending radius and installation temperature for CCS GROUNDING STRAND?

The minimum installed bending radius for CCS GROUNDING STRAND is 10 × OD across its continuous operating temperature range of -50 °C to +200 °C, ensuring mechanical and dielectric stability without conductor or insulation strain.

How are the concentric layers of CCS GROUNDING STRAND arranged from inside to outside?

From inside to outside, the construction sequence is: (01) Low-carbon steel metallurgical core (High-strength annealed or hard-drawn carbon steel core in each individual strand); (02) Metallurgically bonded copper cladding (30%/40% IACS) (Concentric stranded copper-clad steel (CCS) wires per ASTM B452 / ASTM B228).

What factory test certificates are supplied with CCS GROUNDING STRAND?

Every production drum or spool of CCS GROUNDING STRAND undergoes routine conductor DC resistance, dimensional and dielectric/integrity testing per ASTM B452 / ASTM B228 / IEEE 80, and is delivered with an EN 10204 3.1 factory test certificate.
