Roxtec hails free web-based safety tool
International cable and pipe seal provider Roxtec claims its free, web-based tool Roxtec Transit Designer makes it easy for designers and engineers to ensure safety.
Sealing solutions for cable and pipe penetrations are important to protect against a variety of risk factors including fire, gas, water, dust and the risk of explosion.
Roxtec created the design tool to help designers select the most suitable solution and to simplify the process of designing, purchasing and installing multi-cable transits.
“We have more than 10,000 registered users in more than 100 countries. The number is increasing as professionals all over the world realize they can design transits in minutes,” said Roger Johansson, Roxtec executive vice-president.
Users enter cable schedule, sealing requirements, installation preferences and preliminary opening sizes to find the solution they need. The tool helps them filter by application, certificate and requirements, and generates approved 3D models and drawings as well as bills of material and installation instructions.
“Making sure that the team gets it all right from the start is a smart way to reduce project risks in all phases,” said Mattias Persson, application specialist at Roxtec. “There is also a lot of time and money to save by speeding up the entire process.”
He added: “Designers can safely share their work online with project teams anywhere in the world. The tool can also be used offline, as long as the design is finalized online.”
Norvento targets new wind turbine at UK market
Medium-scale wind turbine manufacturer Norvento has unveiled a new model of its nED100 turbine aimed at the UK market.
The re-engineered unit introduces a number of innovations that Norvento says “will simultaneously increase the efficiency of the machine and reduce its up-front and long-term generation costs”.
With a smaller and more compact generator, as well as a lighter, redesigned nacelle and a more efficient 12 metre blade design, the new 100 kW model is designed to enable landowners and commercial users to maximize financial returns and savings in the post-subsidy UK medium wind market.
The launch of the new turbine comes amidst ongoing reductions to feed-in tariff support for onshore wind, which, in conjunction with steadily rising retail electricity prices and falling technology and installation costs, is driving a fundamental shift in the way medium wind projects are deployed in the UK.
The new turbine’s direct drive permanent magnet generator is now lighter and more compact, which Norvento says is tailored to the operational demands of the UK climate. “It maintains the same high performance levels as the original generator, whilst enabling Norvento to use a more traditional nacelle design and a proven direct drive layout, whereby the generator is placed immediately behind the rotor, with a smaller shaft.”
Ivo Arnús, director of UK business development at Norvento, said: “nED100 is the product of extensive research into the UK market, and as the medium wind sector continues to evolve, we’re simply putting into practice a number of lessons learnt from our operational experience to refine a proven design.
“Having reviewed and enhanced our manufacturing process, we’re now able to offer a machine that delivers the same unparalleled performance and efficiency as the existing model at a lower cost.”
Prysmian claims HVDC cable technology ‘breakthrough’
Cable company Prysmian Group is launching what it calls “a breakthrough technology for the development of power transmission grids that will ensure better environmental sustainability, higher electrical performance and lower costs”.
The group has announced the successful development and testing of its new P-Laser 525 kV cable system for high voltage direct current (HVDC) applications.
“This is a significant and important new technology that shapes the progress of HVDC in the cable industry”, said Massimo Battaini, senior vice-president of energy projects.
“We are proud to offer this advanced technology to our customers engaged in developing, extending and upgrading their power grids, while seeking to reduce environmental impacts with solutions that provide them with superior system performance and cost benefit,” he added.
Prysmian said P-Laser is a technology that permits a more efficient cable production with lower environmental impact than traditional XLPE (cross-linked polyethylene). Manufacture is performed in a single and continuous process and does not require chemical reactions to achieve the properties required for the long-term electrical integrity of HVDC insulation systems.
This feature, says Prysmian, gives the benefit of shorter production times and results in both reduced energy consumption as well as lower greenhouse gas emissions.
The company added that P-Laser is particularly suitable for HVDC applications.
