temporary power

US-based Larson Electronics has added a mobile distribution system for industrial applications to its range of industrial grade lighting equipment.

The temporary distribution system is designed to utilise power power sources independently for maintenance and cleaning in hazardous work areas. The system operates with 240V 60Hz AC, which is then stepped down to 120V AC.

"These systems are ideal for indoor and outdoor use applications such as construction sites, plant maintenance, plant turnarounds, hazardous location operations, shows, exhibits, and shipyard operations," said Larson Electronics president Rob Bresnahan.

According to the Texas company, the power distribution system makes 120V AC available with eight 20A.

A 100A load centre protects the main load centre with a main breaker for circuit protection. Two run-flat tires and a cart style-mounting platform are aimed to provide easier substation mobility.

The transformer and distribution assembly is mounted to a standard upright steel dolly cart style frame

The distribution solution can be modified to meet the needs of job-site requirements. “As a manufacturer, we can custom build portable transformer systems to customer specifications,” added Bresnahan.

Aggreko has been selected to provide temporary power to the 2014 World Cup in Brazil.

The deal will see the Scottish power provider supplying temporary power for the broadcasting of all the matches in 12 host cities across Brazil.

In addition, Aggreko will provide power and temperature control services for the International Broadcast Centre in Rio de Janeiro.

Aggreko has a strong presence in South America; having bought Brazil’s largest power rental business— PoitEnergia— in 2012 it is well positioned to provide the necessary power for the championship.

The media coverage of the 64 matches will be watched by three billion people around the world and require Aggreko to supply, install and operate more than 46MW of generating capacity, 1,000 distribution panels and 200 km of electric cables.

Energetix subsidiary Energetix Pnu Power has received a UK patent for an important method relating to the core technology within its compressed air uninterruptible power supply products.

The patent - titled 'Lubrication of Positive Displacement Expanders' - describes the method by which efficiency of the conversion of compressed air into electrical power can be optimised with minimal lubrication of mechanical components. Pnu Power produces back-up power solutions, using compressed air, for utility switching, telecommunications, data centres and other mission critical industrial operations.

Energetix says the grant of this patent provides additional protection to the company's core product platform and builds on the company's intellectual property portfolio relating to its Pnu Power technology.

The company has a core patent granted in 20 countries which protects its compressed air driven UPS system as well as two further patents providing additional protection. 

Quick Cable Corporation has launched a targeted DC power programme including an online catalogue of products for stationary battery dealers, installers and OEM suppliers.

This is in response to the growing market for backup power in fields such as telecom centres, financial institutions, manufacturers and distribution centres requiring DC power from battery systems.

The new catalogue expands Quick Cable’s product portfolio of battery connectors, cables and accessories for DC power requirements.

The power programme brings in UL listed cable options up to 777 MCM, battery containment systems and additional chemical and maintenance products specific to the stationary battery market.

The battery containment systems have been designed around a flexible, model to make it easy to design a system based on battery rack dimensions using the Quick Cable online configuration tool.

Chinese portable power company Powerocks has an ever growing range of mobile phone power boosting accessories. The high capacity portable batteries provide additional power for mobile and tablet devices that are compatible with USB ports.

The lithium-ion batteries can be charged form a mains power supply and then provide several re-charges for smart phones and tablet devices. The slim-line design of iPhones and the like mean the battery cannot be swapped with a spare, it must be recharged, resulting in companies coming up with novel ways to help users re-charge when travelling or away from mains charging.

The range includes the Stone series of portable batteries that offer between 5800mAh and 7800mAh capacity, which provide an additional three times power for devices; The Magicstick is the size of an AA cell and offers 2600mAH power on the go for phone devices. 

The ultimate in portable battery is built into the phone cover. The interestingly named Cheese Crystal is a protective case for the iPhone4 that has an 1800mAH lithium-ion battery incorporated in it to double potential battery life.

When charged, Powerocks range can power up to two devices, dependant on model, two or three times. The designs are complimentary to Apple style and show these chargers can be sleek and elegant but still pack a lot of power.
