9/26/2014
Step-change innovation to provide increased efficiency and sustainability
Borealis and Borouge, leading providers of innovative, value-creating solutions for the wire and cable industry, announce a true step-change high voltage direct current (HVDC) innovation based on the Borlink™ technology platform. Developed in partnership with power and automation technology leader ABB, this major HVDC innovation, supported by a unique track record of 15 years proven operational excellence and industry leadership in extruded HVDC materials, will support the further integration of renewable energies into the grid and the establishment of more interconnections among countries in major infrastructure projects around the world. The new grade, Borlink LS4258DCE, will be introduced to industry partners at the 2014 Cigré Session in Paris, France.
New Borlink™ grade supports extruded DC transmission at extra high voltages
HVDC power transmission supports long-distance electricity transport without significant losses, providing higher efficiency and increased sustainability. The industry trend is clearly moving towards an increased need for higher capacity transmission at high voltage levels. Borealis and Borouge now introduce the next generation HVDC insulation compound, Borlink LS4258DCE, which, along with the accompanying HVDC semicon Borlink LE0550DC, enables the use of extruded cable technology at significantly higher voltage and transmission levels in instances where paper cables are traditionally used. Successful type test qualification of an extruded cable system according to the Cigré recommendation 496 has been achieved at 525 kV based on Borlink LS4258DCE and Borlink LE0550DC. This key performance indicator is made possible by the unique character of the compound providing a high level of both chemical and physical cleanliness to achieve the envisioned step-change in electrical performance.
This unique material is produced by the Borlink technology, which is a complete global package of power cable compounds and expertise with applications for high voltage (HV), including extra high voltage (EHV) and HVDC launched in 2012. Borlink LS4258DCE is an unfilled crosslinked polyethylene (XLPE) compound based on the enhanced base resin technology Supercure. The compound is designed to provide higher cable production efficiency in terms of a shortened cable production cycle, enabled by a significant reduction of degassing burden and improved scorch performance. Offering proven benefits to the industry, it is produced at Borealis' state-of-the-art high pressure production facilities in Stenungsund, Sweden, a plant recently supported by major investments.
Enhancing a proven track record of W&C innovation
As a long-time industry leader, Borealis is dedicated to helping cable manufacturers address the most pressing issues and future needs in the industry. For cable makers, Borlink LS4258DCE will provide step-change technical benefits as well as more efficient and more streamlined means of production. This innovative new grade enables the use of extruded cable technology to produce extra high voltage cables necessary for increased and more efficient transmission capacity. This allows transmission over longer distances and grid integration of remote renewable energy generation. Utilities will be able to benefit from this more efficient use of energy, leading to higher sustainability.
In addition to environmental benefits such as more efficient energy supply, Borealis' innovation also brings a range of societal and economic benefits. An increased number of cables installed underground leads to fewer unsightly overhead lines, contributing to high reliability and contributes to ensuring no risk to human health. Enabling larger amounts of power from renewable energy sources to be delivered to the grid - for example from remote offshore wind farms - will help drive energy change. Making it possible for countries to trade energy by way of interconnectors also promotes energy efficiency and reliability at economic prices.
"Whilst Europe has been at the forefront of technological developments in this area, the trend is now becoming global," explains Anton Wolfsberger, Borealis Marketing Manager for Energy and Infrastructure. "The integration of renewables into the transmission system and interconnections between countries are key factors in achieving greater energy efficiency, and thus of great interest to both policymakers and the general public."
"Borealis' role as a leading innovator on a global scale will be further enhanced by this step-change technology innovation," says Gilles Rochas, Borealis Vice President for Energy and Infrastructure. "In line with our mission in Bringing Energy All Around, we will continue to cooperate with partners and customers along the value chain to deliver tangible benefits not only for the wire and cable industry, but for society as a whole."
The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
