What Are UNE 22560 and UNE 22561? Scope, Definitions, and Core Purpose The UNE 22560 and UNE 22561 standards represent the final and often most underestimated element of the Spanish and Latin American underground mining cable ecosystem. Where UNE 22511 and UNE 22512 govern the power distribution cables that energize mining equipment, the 22560 and 22561 standards govern the signal, control, and interlock cables that command and protect that equipment. These are the "nervous system" cables of a mine — the communication network that tells a continuous miner when to advance and when to halt, that triggers emergency stops, that monitors hoisting rope tension on shaft equipment, that controls conveyor sequencing, and that enables the protective interlocking that prevents a piece of equipment from operating unless all safety preconditions are met. UNE 22560 formally defines flexible multi-core cables for underground mining with voltage ratings up to 500 V or 0.6/1 kV, with no metallic armour protection — designed for installation within equipment enclosures, along protected cable trays in main gate roads, or in areas where mechanical damage risk is minimal. UNE 22561 is its armoured sister standard, incorporating steel wire braid or steel tape protection, specified for installation in rough terrain areas where mechanical damage from rock fall, equipment collision, or floor contact is a credible risk. Both standards mandate that the cable be designed as a multi-core concentric stranded bundle — not the parallel-laid three or four conductors common in power cables, but rather seven, twelve, nineteen, or more individually insulated cores twisted concentrically around a central axis, allowing compact packaging of numerous independent control circuits within a single cable jacket. The distinction between these standards is not merely mechanical armour presence or absence. Control cables are tested against an entirely different set of safety criteria than power cables because their failure mode is fundamentally different. A power cable failure results in loss of energy to equipment — dangerous but localized. A control cable failure can disable the interlock system that prevents a continuous miner from advancing into unsafe ground, or can disable the emergency stop circuit that should halt a conveyor if a worker falls into it. A control cable fire, burning in a tightly bundled cable tray with other control cables, must not spread flame between cables because control cables are typically routed in shared ducts and cable carriers where one cable's ignition could cascade to adjacent circuits. Therefore, control cables are tested for bundle flame propagation (EN 60332-3) rather than single-cable flame propagation tests — a more stringent requirement that demands careful attention to outer sheath formulation and cable spacing in bundle installation.
