TRATOS ASNZS MTO-450® – 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

These Class 1 cables, designed with reduced insulation and sheath thickness, are suitable for supply of power to a wide range of applications, from dragline cable to quay cranes and material handling equipment, where copper screened cable is required but light weight and smaller dimensions are also desired . This cable is suitable for both trailing and slow reeling applications. Class 1 cables are used where light weight and reduced dimensions are required.

  • Conductor: Flexible stranded tinned annealed copper conductor
  • Conductor Screen: Semiconductive compound
  • Insulation: EPR XR-EP-90
  • Insulation Screen: Semiconductive elastomer
  • Composite Screen: Tinned annealed copper braiding interwoven with polyester yarn, covered with a textile reinforced semiconductive tape
  • Filler: Elastomer centre filler
  • Interstitial Earth Conductor×2: semiconductive elastomer covered flexible stranded tinned copper conductor
  • Interstitial Pilot: EPR covered flexible stranded tinned copper conductor

  • Core Identification: Power core identification by coloured tracers in the composite screen (Red, White, Blue) .

Interstitial Earth Cores coloured covering (Black) .

Interstitial Pilot Core identification coloured insulation (Grey) .

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

Application

These Class 1 cables, designed with reduced insulation and sheath thickness, are suitable for supply of power to a wide range of applications, from dragline cable to quay cranes and material handling equipment, where copper screened cable is required but light weight and smaller dimensions are also desired . This cable is suitable for both trailing and slow reeling applications. Class 1 cables are used where light weight and reduced dimensions are required. 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 outwards
  • 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)
    • (e) semiconductive tape over composite screen
  • Laid up around the centre filler
  • Three elastomer covered equal size conductors (two earth and one pilot) disposed into the laid-up power core outer interstices 
  • Reinforced (within sheath) outer sheath of extra heavy-duty elastomer XHD-85-PCP applied to fill the interstices
