PROTOMONT NSHXOEU series represents an advanced category of low voltage flexible rubber cables specifically engineered for demanding mining and industrial environments. These cables feature a specialized EVA-based outer sheath compound (5GM3) combined with EPR (Ethylene Propylene Rubber) insulation, providing an optimal balance of flexibility, durability, and environmental resistance for medium mechanical stress applications.
The designation NSHXOEU follows the German cable nomenclature system established by DIN VDE standards, where each letter indicates specific construction characteristics. The “X” in the designation indicates the halogen-reduced EVA sheath compound, while “H” denotes the heavy-duty rubber construction suitable for harsh environments. According to Eland Cables, DIN VDE 0250 has achieved global recognition as the ultimate standard for tough rubber sheathed flexible cables, particularly for mining and material handling equipment.
BS 6708 Type 21 mining cable represents an advanced variant of galvanized steel pliable wire armoured flexible cables specifically engineered for demanding mining and quarrying applications requiring a dedicated fourth earth conductor. This four-core configuration distinguishes Type 21 from the three-core Type 20, providing enhanced safety features and compliance with electrical regulations that mandate separate protective earth conductors in mining installations.
Key Identification: Type 21 cables feature four unscreened cores (three phase conductors plus one earth conductor) laid up around an elastomeric cradle without contacting each other, protected by galvanized steel pliable armour between inner and outer sheaths. Rated at 640/1100V with a 3kV test voltage, these cables are designed for use in deep mines where explosive gases and dust can accumulate, as well as surface operations supplying excavating, crushing machines and equipment.
BS 6708 Type 20 mining cable represents a specialized category of galvanized steel pliable wire armoured flexible cables engineered for the most demanding mining and quarrying applications. This cable type is characterized by its robust construction featuring three unscreened cores laid up around an elastomeric cradle without contacting each other, protected by galvanized steel pliable armour that provides exceptional mechanical protection while maintaining the flexibility essential for mobile mining equipment applications.
Key Identification: Type 20 mining cables are classified within BS 6708 as cables with galvanized steel pliable wire armouring, featuring unscreened cores and a rated voltage of 640/1100V. These cables are specifically designated for use in deep mines where explosive gases and dust can accumulate, as well as surface operations for supplying excavating, crushing machines, and equipment requiring robust mechanical protection.
