TRATOS ASNZS MTO-412® – Class 2 – 1,1/1,1 kV

REELING & TRAILING CABLES BASED ON AS/NZS 2802

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

AS/NZS 2802 specifies two classes of cables for reeling and trailing cables for mining and general use, and defines cable structures developed to satisfy particular industry requirements. For high voltage applications, cables with a rationalized range of conductor sizes are specified to provide an optimum range to meet most applications.

Pliable Wire Armoured cables mainly used as heavy duty feeder cables for power supply where maximum mechanical protection and strength is required. Can also be used as the feeder to machinery, transportable mining substation and ancillary equipment that has to be moved intermittently.

All cables with a voltage rating of 1,1/1,1 kV have a separator tape over the power core conductor, an extruded EPR insulation.

Three such unscreened power cores are laid up around a centre filler with a seperate EPR insulated earth core in each interstice.

Core identification as follows: Power core identification by coloured insulation (Red, White, Blue). Earth Core identification by coloured insulation (Green/Yellow) .

The core assembly is covered by a General Purpose PCP inner sheath.

Heavy duty Pliable Wire Armour made up of strands of Galvanised Steel Wire applied helically.

Sheathed overall by a Heavy duty HD-85-PCP sheath Black (other colours on request).

While the requirements of underground coal mining continue to determine the cables to be incorporated into Standard AS/NZS 1802, it is recognized that many of these cables will be equally applicable to other installations, for example, underground metalliferous mines, ship loaders, travelling cranes, reclaimers at loading stations and other materials handling plants.Other requirements may apply in these applications.

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.

Application

Pliable Wire Armoured cables used for supplying fixed or semi-permanent equipment where maximum mechanical protection and strength is required.such as pumps, conveyors etc., they are also used as semi-permanent distribution cables to pieces of equipment that have to be moved intermittently. Not suitable for reeling. 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.
