Yet every\u00adthing is fine. All the bush\u00adings and insu\u00adla\u00adtors make it through the intense quak\u00ading unscathed and pow\u00ader can con\u00adtin\u00adue to flow. This is the result every grid oper\u00ada\u00adtor hopes for in this kind of extreme sit\u00adu\u00ada\u00adtion.<\/p>\n

Out\u00addoors, how\u00adev\u00ader, insu\u00adla\u00adtors are also exposed to many oth\u00ader stress\u00ades.

NEW MATERIALS<\/h2>\n

Ceram\u00adic insu\u00adla\u00adtors have a long tra\u00addi\u00adtion in such appli\u00adca\u00adtions. How\u00adev\u00ader, they have been left behind in recent years in favor of hol\u00adlow com\u00adpos\u00adite insu\u00adla\u00adtors. These insu\u00adla\u00adtors are more light\u00adweight and eas\u00adi\u00ader to han\u00addle. Porce\u00adlain insu\u00adla\u00adtors burst dur\u00ading an earth\u00adquake or when van\u00addal\u00adized, dam\u00adag\u00ading sur\u00adround\u00ading equip\u00adment in the process and, in some sit\u00adu\u00ada\u00adtions, even pos\u00ading a risk to peo\u00adple.

This is why Hochspan\u00adnungs\u00adger\u00e4te GmbH (HSP) in Trois\u00addorf, Ger\u00admany near Cologne has been rely\u00ading on hol\u00adlow com\u00adpos\u00adite insu\u00adla\u00adtors for many years. The lead\u00ading glob\u00adal man\u00adu\u00adfac\u00adtur\u00ader of high-volt\u00adage bush\u00adings for trans\u00adform\u00aders, wall bush\u00adings and gas-insu\u00adlat\u00aded switchgear (GIS) was the first cus\u00adtomer for which Maschi\u00adnen\u00adfab\u00adrik Rein\u00adhausen (MR) pro\u00adduced ReCoTec\u00ae insu\u00adla\u00adtors in 2007. Their spe\u00adcial fea\u00adture: Instead of being made of porce\u00adlain, these insu\u00adla\u00adtors are com\u00adposed of glass-fiber-rein\u00adforced plas\u00adtic with sil\u00adi\u00adcone shield\u00ading<\/p>\n

MR already had a great deal of expe\u00adri\u00adence with insu\u00adlat\u00ading mate\u00adri\u00adals. \u201cFor over 30 years, we\u2019ve pro\u00adduced insu\u00adlat\u00ading tubes with com\u00adplex elec\u00adtri\u00adcal require\u00adments for use on our tap chang\u00aders our\u00adselves. This is where the idea came from to get into the busi\u00adness of hol\u00adlow com\u00adpos\u00adite insu\u00adla\u00adtors,\u201d says Dr. Bernd Kem\u00adpa, Man\u00adag\u00ading Direc\u00adtor of Rein\u00adhausen Pow\u00ader Com\u00adpos\u00adites GmbH.<\/p>\n

PERFECTION FOR SAFETY<\/h5>\n

ReCoTec\u00ae insu\u00adla\u00adtors have rig\u00ador\u00adous require\u00adments regard\u00ading mechan\u00adi\u00adcal loads, seal-tight\u00adness and dielec\u00adtric strength. The prop\u00ader\u00adties of the com\u00adpos\u00adite mate\u00adri\u00adals are cru\u00adcial for the qual\u00adi\u00adty and reli\u00ada\u00adbil\u00adi\u00adty of the prod\u00aducts, and per\u00adfect com\u00admand of the pro\u00adduc\u00adtion process is there\u00adfore nec\u00ades\u00adsary.<\/p>\n

ReCoTec\u00ae insu\u00adla\u00adtors con\u00adsist of an insu\u00adlat\u00ading tube made of glass fiber-rein\u00adforced plas\u00adtic (GFRP), alu\u00adminum fit\u00adtings and a sil\u00adi\u00adcone shield\u00ading. They are designed per\u00adfect\u00adly for the respec\u00adtive appli\u00adca\u00adtion in accor\u00addance with spe\u00adcif\u00adic cus\u00adtomer require\u00adments. The lam\u00adi\u00adnate struc\u00adture of the GFRP tube is essen\u00adtial for the mechan\u00adi\u00adcal and elec\u00adtri\u00adcal prop\u00ader\u00adties.<\/p>\n<\/div>\n<\/div>\n

CLOSE PARTNERSHIP<\/h2>\n

Owing to the many advan\u00adta\u00adgeous prop\u00ader\u00adties of the inno\u00adv\u00ada\u00adtive mate\u00adri\u00adals, demand has grown steadi\u00adly for ReCoTec\u00ae hol\u00adlow com\u00adpos\u00adite insu\u00adla\u00adtors and oth\u00ader prod\u00aducts under the Rotafil\u00ae brand name. This is why MR found\u00aded Rein\u00adhausen Pow\u00ader Com\u00adpos\u00adites GmbH (RPC) back in 2009. Through all the years, RPC and the first cus\u00adtomer of hol\u00adlow com\u00adpos\u00adite insu\u00adla\u00adtors have remained close. Last year, the 10,000th insu\u00adla\u00adtor was sent to HSP in Trois\u00addorf.<\/p>\n

\u201cWhen we start\u00aded pro\u00adduc\u00adtion of ReCoTec\u00ae ten years ago, insu\u00adla\u00adtors made of porce\u00adlain were still the stan\u00addard. Today, hol\u00adlow com\u00adpos\u00adite insu\u00adla\u00adtors are tak\u00ading over more and more of the mar\u00adket.\u201d Dr. Bernd Kem\u00adpa, Man\u00adag\u00ading Direc\u00adtor of RPC<\/cite><\/p><\/blockquote>\n

Dr. Kem\u00adpa is con\u00adfi\u00addent that the mar\u00adket for hol\u00adlow com\u00adpos\u00adite insu\u00adla\u00adtors will con\u00adtin\u00adue to grow, \u201cEner\u00adgy con\u00adsump\u00adtion will steadi\u00adly increase around the world. In Chi\u00adna and India, for exam\u00adple, there are many new high-volt\u00adage direct cur\u00adrent (HVDC) trans\u00admis\u00adsion net\u00adworks for volt\u00adages up to 1100 kV DC. It would scarce\u00adly be pos\u00adsi\u00adble to imple\u00adment appli\u00adca\u00adtions at these volt\u00adage lev\u00adels using porce\u00adlain.\u201d<\/p>\n

Small\u00ader wall thick\u00adness\u00ades are pos\u00adsi\u00adble due to the high strength of the glass-fiber-rein\u00adforced plas\u00adtic.
