Protective pipes shield wind farm’s high voltage cables
Egeplast has supplied protective pipes for high voltage cables in a wind farm project in Germany. BorWin5 is a 230km grid connection connect- ing the EnBW He Dreiht wind farm – on an island north of Borkum – to a high voltage onshore grid, with a connection point at a converter station at Garrel. The total length of
underground cable is 120km. For the construc- tion work, transmission system operator Tennet opted to install almost 7km of Ege-Com Macrod- uct High-T PE pipe, and almost 1km of Macroduct Mono PE. The pipe was installed using horizontal directional drilling (HDD). Macroduct High-T is a
protective pipe for high and extra high voltage
PEX HDPE gains highest chlorine resistance
Borealis says that it has received the highest chlorine resistance accreditation for its HE1878E-C2 grade of HDPE – which is tailored for PEX production. The company says that the material – which has now achieved a Class 5 listing
– provides end-users with more peace of mind as it meets the higher require- ments of resistance to disinfectants in hot and cold water pipe applications. The new accreditation complies with the ASTM F876 standard for PE
crosslinked pipes, it says. The material offers high temperature resistance and flexibility, and low creep. Its stabilisation package also opens it up for use in certain industrial applications. Borealis adds that the material increases efficiency by reducing production
steps, requiring the addition of peroxide only and minimising the risk of additive dosing errors. Also, it removes the need for separate additive purchas- ing and stockholding and improves safety through minimised handling. �

cables of up to 525kV that provides enhanced thermal stability – enabling it to withstand the high thermal stresses involved. The combination of high flexibility and solidity provided the optimum properties required for performing these horizontal drilling operations, said Egeplast.
“Due to delivery via ferries – and limited storage capacities on the island – ex- actly timed delivery and
direct and easy contact to egeplast, with short re- sponse times, are a critical success factor,” said Thomas Schwindeler, project manager of project partner Strabag. “As a system provider, Egeplast supplies the entire range of accesso- ries – with components including temperature- resistant electrofusion couplers in OD 450 as well as temperature resistant stub flanges.” �

of WPCs Nusaned Investment has invested in Saudi company Suhul Alkhalej – which is to make a range of products including wood-plastic composite (WPC) profiles for decking and cladding, WPC sheets and doors, and PVC profiles for windows and doors. The deal between Nusaned and Suhul Alkhalej will use raw materials from SABIC, which is the owner of Nusaned. “The new venture fulfills our mandate of investing in industrial SMEs in [Saudi Arabia],” according to Faisal Al-Bahair, CEO of Nu- saned Investment. “It will use polymers as raw mate- rials promoting sustain- ability and downstream initiatives.” �
