Earthing, lightning and surge protection systems are critical for safeguarding electrical installations and personnel against overvoltages caused by lightning strikes, switching transients, or grid faults. These products include earthing rods, conductors, clamps, lightning arresters, surge protective devices (SPDs), and equipotential bonding bars. Key technical parameters include nominal discharge current (In), maximum continuous operating voltage (Uc), voltage protection level (Up), and impulse current (Iimp) for Class I arresters. Earthing components are rated by material (copper, galvanized steel, stainless steel), diameter, and corrosion resistance, while SPDs are classified by Type 1, Type 2, or Type 3 depending on installation location and energy handling capacity.

These systems are deployed in a wide range of sectors including industrial plants, commercial buildings, residential complexes, telecommunications infrastructure, renewable energy installations (solar PV and wind farms), and critical facilities such as hospitals and data centers. They are installed in main distribution boards, sub-distribution panels, and at the point of entry for overhead lines or external services. Equipotential bonding is essential in bathrooms, swimming pools, and hazardous areas to prevent step and touch voltages.

Key subcategories include earthing rods (e.g., copper-bonded steel rods in lengths of 1.5m, 2m, 3m with diameters of 14mm, 16mm, 20mm), earthing conductors (bare copper tape or stranded cable), lightning arresters (Class I, II, III), surge protective devices for AC and DC systems, and equipotential bonding bars. Article codes often follow patterns like ER-14-1500 for earthing rods (material, diameter, length) or SPD-2P-40 for surge protectors (type, poles, kA rating). Main articles include copper earthing rods, galvanized steel clamps, Type 2 SPDs for 230/400V systems, and bonding bars with 4 to 12 terminals.
