Purpose: This standard provides a uniform earthing and bonding guide for radio/microwave stations to ensure consistency and clarify past ambiguities. It is applicable to Eskom Holdings Limited and its Telecommunications division.

Scope: The document specifies earthing and bonding requirements for a typical radio/microwave station, forming an integral primary lightning protection system for the station and its equipment. It does not cover secondary or tertiary protection (e.g., circuit arrestors, spark gaps, or internal equipment protective devices).

Key Points:

• The standard applies to radio/microwave terminals or repeaters (High Sites) with antennas mounted on towers, signal feeder cables, equipment buildings, auxiliary supplies, and fenced areas.
• Stations with slightly different geometries must follow this standard as closely as possible.
• The standard is periodically revised and references SANS 10199 for earth electrode design and installation.

Scope: Supply, delivery, construction, and erection of a 25m tower at Naboomspruit Substation (LimLanga Cluster, Limpopo) for 12 months. The project must adhere to Eskom's Radio Station Earthing and Bonding Standard (Ref: 240-56872313, Rev 3).

Key Technical Requirements:

• Tower Structure: Metallic lattice or concrete tower with a 25m height. Must include air termination (lightning spike) if required: a single galvanised steel spike (min 2m high, 150mm² cross-section) bolted to the uppermost leg of the tower. All tower structures with working platforms at the top must have a spike unless an antenna is installed at the highest point.
• Tower Earthing: Lay a 150mm² copper bar ground ring at a depth of ≥500mm around the tower. Bond all tower legs to the ground ring below ground level using 150mm² copper strips and Sebra alloy or copper-flow brazing rods. Install two 150mm² copper radials (buried ≥500mm deep) from the tower ground ring to the fence posts.
• Antennas and Feeders: Bond metallic antennas to the metallic support structure. Use cat ladder bonding plates (clamped to the cat ladder) for feeder and equipment bonding, connected with M8 brass bolts, nuts, and washers. Plates must be fitted 500mm below the top of the tower (first bonding point), 500mm below any lower equipment, and at the tower base for cables/waveguides.
• Equipment Building Earthing: Provide an external buried ground ring (150mm² copper strip, ≥500mm deep, 100mm from the foundation). Bond the ground ring to the tower structure. Run two radials from the ground ring to the fence corner posts. Ensure single-point earthing for the building/container, with all cables (signal and power) entering from the same side and point. All lightning protection must occur at this point.
• Internal Bonding: Install an earth bus (25mm x 3mm flat copper bar) in the cable tray, as close as possible to the equipment. Connect equipment frameworks, racks, and metallic objects (e.g., IDF, doors, metallic roof) to the earth bar using straight conductors (min 16mm² cross-section). Bond the internal earth bar to the external building ground ring.
• External Metallic Objects: Bond all metallic objects within the fence to the ground equipotential ring. Bond the station fence to the tower ground ring and connect the two gateposts with a 150mm² bonding strap. Bond any crossing or proximate earthing/bonding strips together.
• Auxiliary Supply: Route supply cables to enter the building from the same side as other cables. Bond the cable armouring to grounded metal at the entry point. Run a 150mm² earth strip parallel to the AC supply cable, bonded to the building earth ring at one end and the secondary neutral ground at the other. Interconnect the primary surge arrestor ground to the secondary neutral ground. If supplied by a nearby substation feeder, bond the earthing strip to the substation earth mat.
• Copper Theft Prevention: Backfill copper trenches with a mix of 10% cement and compact. Cast a concrete apron around the building and fence. Paint all exposed copper with aluminium paint to disguise it.

Standards and References:

• Compliance with SANS 10199: "The Design and Installation of an Earth Electrode."
• Brazing: Use Sebra alloy or copper-flow brazing rods for 150mm² copper earth straps. Cad welding is prohibited.
• Inspection: All earthing installations must be inspected and signed off by an Eskom representative before covering. Photographs of all earth connections must be taken for record-keeping.

Earthing and Bonding Methodology:

• Tower Earthing: Lay a 150mm² copper ground ring (≥500mm deep) around the tower. Bond all tower legs to the ring below ground using 150mm² copper strips and Sebra alloy/copper-flow brazing rods. Install two 150mm² copper radials (≥500mm deep) from the tower ground ring to the fence posts.
• Antennas and Feeders: Bond metallic antennas to the tower structure. Use cat ladder bonding plates (M8 brass bolts, nuts, washers) for feeder/equipment bonding, positioned 500mm below the top of the tower, lower equipment, and at the tower base.
• Equipment Building: Install an external 150mm² copper ground ring (≥500mm deep, 100mm from foundation). Bond to the tower structure and run two radials to the fence corner posts. Ensure single-point earthing with all cables entering from the same side.
• Internal Bonding: Use a 25mm x 3mm copper earth bus in the cable tray. Connect equipment frameworks, racks, and metallic objects (e.g., doors, roof) with straight conductors (min 16mm²). Bond the internal earth bar to the external ground ring.
• External Metallic Objects: Bond all metallic objects within the fence to the equipotential ring. Connect the fence to the tower ground ring and bond the two gateposts with a 150mm² strap. Bond crossing or proximate earthing strips.
• Auxiliary Supply: Route cables to enter from the same side as other cables. Bond armouring to grounded metal at entry. Run a 150mm² earth strip parallel to the AC supply, bonded to the building earth ring and secondary neutral ground. Interconnect primary surge arrestor ground to secondary neutral ground. For substation feeders, bond the earthing strip to the substation earth mat.
• Copper Theft Prevention: Backfill trenches with 10% cement mix, compact, and cast a concrete apron around the building and fence. Paint exposed copper with aluminium paint.

Quality Assurance and Inspection:

• All earthing installations must be inspected and signed off by an Eskom representative before covering the earth mat.
• Ensure no poorly brazed or high-resistance connections are present.
• Photographs of all earth connections must be taken and retained for record-keeping purposes.
