Nexans To Supply Cable Link For Desalination Plant

Nexans is to supply a high-voltage underground cable link that will power an Australian seawater desalination plant, which is currently under construction in the state of Victoria. The contract covers the supply of around 260km of 220kV XLPE cable, made and tested as a 275kV cable, to Thiess Degremont, which is contracted to design and construct the EUR2.2bn (GBP2bn) Victorian Desalination Project to deliver up to 150 billion litres of water a year to Melbourne and regional communities.

The Victorian Desalination Project includes an 84km underground pipeline to connect the reverse-osmosis plant to a transfer main and then back to the reservoir. The electric power required by the new plant will be supplied by the 87km-long underground cables co-located with the pipeline, creating the world's longest high-voltage AC underground link operating at this power level.

An underground link was the preferred option for the project since it is both more energy efficient and secure than overhead lines and will also have the least impact on landowners, farmers and other people living and working in the area. Olex, a Nexans company serving the Australian and Asia-Pacific markets, will produce 225km of the underground cable locally at its Tottenham facility in Victoria.

It will be manufactured on equipment recently installed as part of a EUR12.5m upgrade that now enables Tottenham to produce XLPE (cross-linked polyethylene) cables up to 500kV. The remaining length of cable will be supplied by the Nexans factory located in Charleroi, Belgium. The cable will be supplied progressively throughout 2010.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
