Definitions

  • the object of the invention refers, in general, to a cable with protective outer sheath for cables. More specifically, the object of the invention refers to a cable with outer sheath for protection against fire for thick industrial cables that are used on winders and port facilities and similar environments.
  • the known cables offer limited fire protection. To obtain effective fire protection, it is necessary for all the cables used (and housed inside the sheath) to be fireproof; and even in this case, the fire protection is different for each cable, depending on its own characteristics.
  • the object of the invention solves this problem, as it ensures that the outer sheath offers effective fire protection without increasing costs or offering overprotection.
  • the sheath that is the object of the invention, it is possible to use cables that of themselves do not offer fire protection (or with very limited fire protection) and place them inside the sheath, the assembled unit offering effective fire protection and complying with fire protection regulations which are mandatory in these types of installations.
  • the object of the invention refers to a protective sheath for cables; specifically, a sheath for protection against fire for thick industrial cables that are used in port and similar facilities characterized in that it is structured in, at least one inner layer, which is a nonwoven band and comprises the first insulation that keeps the cables arranged together inside the sheath; an inner sheath which is of fireproof material and is attached outside of said inner layer, forming jointly with it a primary insulation; an armour made of light and resistant material, which resists high temperatures and provides a high degree of protection against fire, and simultaneously, great rigidity to the assembled unit; and an outer sheath that comprises an outer covering, also of fireproof material; so that, in the joint performance of outer sheath, armour, inner sheath and inner layer, the cable is provided with fire protection for at least 20 minutes (according to standard IEC60332-3).
  • Figure 1 represents a general section of the protective sheath for cables which is the object of the invention, inside of which several cables are arranged (C).
  • the object of the invention is a protective sheath for cables (C), in particular, industrial cables of great dimensions and weight, used in port and similar facilities.
  • the protective sheath which is the object of the invention can contain identical cables (C) (with the same functions and/or task) or different cables (C) (with different functions and/or task) without thereby essentially altering the invention.
  • the sheath which is the object of the invention contains six cables (C): five peripheral cables distributed around a central one.
  • the number and distribution of cables (C) arranged inside the sheath do not matter for the purpose of the invention; likewise, it does not matter whether said cables (C) are identical to or different from each other.
  • the protective sheath for cables is structured of at least:
  • outer sheath (4), armour (3), inner sheath (2) and inner layer (1) with its structure and specific particularities give the resulting covering a fire protection with a duration of at least 20 minutes after starting.
