Physical & electrical characteristics
Product Overview
Type 275 cables are specifically designed for use with high-speed reeling equipment on shuttle cars operating underground. These cables endure some of the most demanding mechanical stresses, including resistance to “corkscrewing” caused by constant twisting and winding in harsh mining conditions. Constructed to meet AS/NZS 1802 standards, Type 275 delivers reliable power supply performance with a robust build that ensures durability and flexibility.
Product Features
Designed for extreme underground conditions: Special cable construction resists twisting and "corkscrewing" effects during rapid reeling on shuttle cars.
Robust and flexible: Non-individually screened power cores with a semiconductive cradle and filler for mechanical stability and flexibility.
Durable sheath: Semiconductive elastomer filled sheath with open weave reinforcement beneath a heavy duty HD-85-PCP outer sheath.
Fire Retardant: Meets fire retardant requirements per AS/NZS 1802.
Reliable Electrical Performance: Core colours for easy identification and single extensible pilot for system control.
Application Areas
Ideal for shuttle cars equipped with high-speed reeling systems in underground mining environments, where cables are subject to constant twisting and mechanical stress.
Installation and Maintenance
Suitable for installation in free air and on mobile equipment. Installation should follow recommended AS/NZS guidelines with regular inspections to maintain cable and sheath integrity.
Customization Services
Cable constructions and lengths can be customized to meet specific project demands upon request.
