A well designed and properly installed electrical infrastructure is crucial for the safe and efficient operations of mines and tunnel excavations. There are various methods of installing mining cables, both on the surface and underground. From suspension and cleats to ducts and trenches, each installation method plays a significant role in ensuring the longevity and reliability of our mining cables through thought-out ease of installation for manual handling safety, ensuring relevant mechanical protection and standards compliance. A. Surface Installations a. Suspension: mining cables can be suspended using our CAB cable management products from centenary wires or wall hooks. This method is suitable for areas where the cable needs to be elevated. See our CAB cable management products here b. Cleats: Cleat fixing is used when the cable runs along the side of a building and cleats securely hold the cable in place. c. Ducts: for cables installed along a designated path, a duct is created by digging a trench and utilising precast concrete segments. Brackets or cleats fasten the cable to the duct’s walls ensuring a stable and protected installation. Additional spacing can be undertaken via cable tray and supports to ensure spacing and ventilation. d. Wall Brackets: Inside buildings cables can be secured to walls with brackets bolted to the wall to provide damage to cables. e. Trench: when burying cables, a cable trench of adequate depth is excavated considering the operating voltage and site conditions. The cable is placed on a bed of sand and covered with additional sand. Interlocking cable tiles are placed on top to provide continuous cover, followed by a layer of earth. Marker posts are erected to indicate the cable trench route. f. Shaft installation: Vertical cable installation in a shaft involves clamping the cable at regular intervals using wooden cleats. The cleats are bored individually to fit the cable securely, ensuring a firm grip. B. Lowering the Cable – Single point Suspension and standard cable installation In shaft installations, cables are typically lowered into the shaft using a drum-mounted system or runway system depending on cable weight and length of run. Cables that can be secured within the winder shaft can be secured within the cage. As the cage descends, the cable is laid out and anchored at the shaft top. An alternative method involves lashing the cable to an engineered design utilising wire suspension ropes. C. Underground Installations In underground mining, cable installations near the pit bottom may utilise cleats on brackets or cable hangers to secure cables to walls. In roadways and gate roads, cables are commonly suspended from the roof or rib bolt bars or arches. Maintaining slackness in the cable is crucial to accommodate roof movements and prevent strain.

Furthermore, regular maintenance is essential to ensure the safety and reliability of these cables. Australian Power Equipment provides mining cables and operational strategies that ensure the reliability and durability of mining cables that are paramount for efficient resource production. 2. Distribution Cables; Evolution and Usage in Mines In current mining operations, PVC/XLPE and LSOH insulated cables with metric dimensions are predominantly used for medium and low-voltage distribution applications. Prior to the introduction of XLPE technology paper insulated Lead sheath Steel Wire Armoured cables, PILSWA ( Metric and imperial sized) were common and are still in use today. The previous PILSWA cables were robust in design however have a significantly lower current carrying capacity AND production of Lead Sheathed cables has decreased. Cables to 2802 are available primarily in three core + 3 earth+ pilot configurations with three-core cables being the norm for three-phase AC distribution systems on an IT earthed system with 5amp earth fault limitation utilising quick-release receptacles. 3. Cable Construction and Features. The conductors of mining cables are typically laid up together in a spiral arrangement. The cores can consist of multi-stranded tinned copper semi-conductor layering insulated with R-EP-90. Any gaps between the mining cable conductors and central pilot core are filled with a semiconductor cradle to achieve a uniform circular section covered with an open weave braid and overall covered by heavy-duty elastomer outer sheath. Mining cables are available in semi-conductor screened, 241 and both single-armoured and double-armoured types. The armour layers, consisting of galvanised steel wires spirally laid along the cable, serve as mechanical protection. Double-armoured cables employ a separator of compounded fibrous tape between the two armour layers, with the galvanised wires spiralled in opposite directions.
