Raychem Heat-shrinkable Indoor TerminationsEPKT for Belted MI Paper Insulated Cables upto 17.5 kV


Raychem Heat-shrinkable Indoor Terminations EPKT for Belted MI Paper InsulatedCables up to 17.5 kVA Raychem 12 kV termination forbelted MI paper insulated cablesinstalled by a utility in Austria.For over thirty years Raychem heatshrinkablematerials have providedjoint ing, sealing and corrosionprotection systems for the evergrowing demands of the world ofenergy. Special materials withenhanced electri cal properties andhigh environmental resist ance form thebasis for products which undergocontinual updating and development.Experience gained from the hugenum ber of products in service withmany of the world s utility companieshas proved their reliability in amulti tude of different locations andcon ditions.As a pioneer in the development ofheat-shrinkable technology we haveseen confirmed the integrity of itsfast, simple and reliable install ationtechniques catering for many differentcable sizes whilst reduc ing the skillsensitivity of installation.Cable accessory kits available formost requirements make simple thesteps required to complete a highlyintegrated and reliable installation.The tough transparent oil reservoirper mits easy visual inspection andmain tenance, and the heat-shrink ableoutlets provided with pre-coatedadhesive allow a simple install ation.The photograph shows the lower endof the reservoir already fitted to thelead sheath with the upper outletsin the process of installation, allprotected against humidity and dustby rigid heat-shrinkable tubing.Transition sealing from connectinglug to cable core are protected byadhesive lined sleeves shrunk intoplace. Power may be switched on oncethe termination is filled with oil andconnected.Ease of installationRaychem terminations for belted MIpaper insulated cables up to 17.5 kVharness the abilities of heat-shrink ablematerials and special adhesives toform a durable seal against cable oiland moisture penetration.This system eliminates plumbing,soldering, gaskets or other skillsensitive operations. After preparingthe cable in the normal way, the cablecores are protected with heat- shrink -able tubing. Installation of atrans parent oil reservoir with ends ofheat- shrink able material and sealingsleeves over the cable lugs com pletesthe termination, which can then befilled with oil and con nected. Each kitcovers a range of cable sizes, comeswith detailed instructions, and requiresno special installation tools orequipment.Special purpose materialsLong term reliability requiresresist ance to oil and pressure in humidindoor conditions. In order to copewith these requirements the heatshrinkablecom ponents are formu latedfrom rigid poly meric materials special lydeveloped by us to withstand highhumidity under electrical stress.Sealing without plumbing orsolderingPre-coated, heat-activated specialadhes i ves are provided on oilreservoir outlets and sealing bootsfor a durable and inspectable sealto the cable sheath, cores andconnect ing lugs. The result is anoil tight moisture barrier from cableto lead sheath.Lightweight and compactThe practically unbreakable oilreservoir and lightweight polymerictubings make the ter mination lightand easy to handle and in s tall, eachkit consisting of only a few dis cretecomponents. As the whole outsidesurface of the termination isinsulat ing, a long creepage path isobtainable with a short overall length.PerformanceExtensive laboratory test programmesand field trials were followed byinstallation of large numbers of theseterminations by utilities, where longtermservice has con firmed theperformance of the system. Raychemterminations for MI paper insul a t edcables meet Raychem specificationPPS 3013, which encompasses therequirements of the major nationalstandards and inter national norms.Technical field serviceRaychem power cable terminationsare the result of a sustained researcheffort and long experience oftechnical field service. We support ourcustomers at every step, from specificproduct development and selection,through laboratory and field testing,to training of customer operators incable pre paration and installationtechniques. As the leader in heatshrinkable materials and one of thelargest cable accessory manufacturers,Raychem makes a wide range ofjointing, sealing and corrosionprotection systems to meet thedemands of the growing world ofenergy.1energy.te.com
