TRATOS ASNZS MTO-455® – Class 1 – from 3,3/3,3 to 33/33 kV

REELING & TRAILING CABLES BASED ON AS/NZS 2802:2000

Special Cables / Mining and Tunneling Cables / Tratos AS/NZS Mining Cables

Designed with reduced insulation and sheath thickness, no cradle, 2 earth and 1 pilot core (each earth and pilot are the same size) in the outer interstices . These cables are suitable for reeling and trailing applications where minimal diameter and mass is desired, particularly suited to stacker-reclaimer applications.

  • Conductor: Flexible stranded tinned annealed copper conductor
  • Conductor Screen: Semiconductive compound
  • Insulation: EPR XR-EP-90
  • Insulation Screen: Semiconductive elastomer
  • Filler: Elastomer centre filler
  • Interstitial Earth Conductor: semiconductive covered flexible stranded tinned copper conductor
  • Interstitial Pilot: EPR covered flexible stranded tinned copper conductor
  • Textile Reinforcement: Open-weave braid reinforcement • Outer Sheath: TRATOS OUTER SHEATH®, better than extra-heavy duty PCP sheath (XHD-85-PCP) .  Extra-heavy duty CPE/CSP sheath can be offered upon request
  • Standard colour: black
  • Marking: TRATOS + XR-EP-90/XHD-85-PCP + TYPE 455 .6 + YEAR + SIZE + Metre Mark
  • Core Identification: Power core identification printed core numbers on the black semiconductive insulation screen. Interstitial Earth Cores coloured covering (Black). Interstitial Pilot Core identification coloured insulation (Grey).

Rated voltages from 3,3/3,3kv up to 33/33kv.

The cables specified in Standard AS/NZS 2802 have been designed to meet the special requirements of the Australian surface mining industry and also to comply with the requirements of AS 3007, Electrical installations—Surface mines and associated processing plant (all parts).

Although surface mining was a significant factor in determining the cables to be incorporated into Standard AS/NZS 2802, it is recognized that many of these cables will be equally applicable to other installations, e.g. underground metalliferous mines, ship loaders, travelling cranes, reclaimers at loading stations and other large materials handling plant.

A number of cables specified in this Standard might also meet the requirements for underground coal mines; however, reeling and trailing cables for coalmines are the subject of AS/NZS 1802, Electric cables—Reeling and trailing—For underground coal mining purposes.

STANDARDS

  • AS/NZS 2802
  • AS/NZS 1125
  • AS/NZS 3808

Application

Designed with reduced insulation and sheath thickness, no cradle, 2 earth and 1 pilot core (each earth and pilot are the same size) in the outer interstices . These cables are suitable for reeling and trailing applications where minimal diameter and mass is desired, particularly suited to stacker-reclaimer applications Cable users will be assisted in making the appropriate cable selection by reference to the descriptive tables of cable types in Standard AS/NZS 2802.

CONSTRUCTION

From centre out
  • Elastomer centre filler
  • Three power cores of equal cross-sectional area, each comprising—
    • (a) conductor
    • (b) semiconductive conductor screen
    • (c) insulation (Class 1) XR-EP-90
    • (d) insulation screen (semiconductive elastomer and composite)
  • Laid up around the centre filler
  • Three elastomer covered conductors (two earth and one pilot) disposed into the laid-up power core outer interstices
  • Tape over laid-up core assembly 
  • Reinforced (within sheath) outer sheath of extra heavy-duty elastomer XHD-85-PCP applied to fill the interstices.
  • Standard colour: black
  • Marking: TRATOS + XR-EP-90/XHD-85-PCP + TYPE 455 .6 + YEAR + SIZE + Metre Mark
  • Core Identification: Power core identification printed core numbers on the black semiconductive insulation screen. Interstitial Earth Cores coloured covering (Black). Interstitial Pilot Core identification coloured insulation (Grey).
