All products are developed using Raychem 's extensive service experience, as per the international standards including IEC, IEEE, ANSI and many national standards. Medium Voltage Raychem 's polymeric surge arresters for voltage power distribution systems upto 800kV are Surge Arresters designed to reliably protect your valuable assets from over voltage.

2 They withstand severe For indoor and outdoor applications, outdoor exposure over long operating lifetime for protection of overhead lines, DC. and help maintain service reliability in locomotives, switchgear applications both overhead and underground installations. and motor protection Raychem 's polymeric surge arresters have passed the most rigorous tests (IEC 60099-4, ANSI , IEC 61643). High Voltage Advantages Surge Arresters For protection of transmission All our arrester are manufactured using systems up to 800 kV. ZnO varistors, which display excellent thermal and current handling characteristics due to the guaranteed homogeneity of the varistor volume. This thermal behavior yields products with: DA Series Excellent temporary overvoltage (TOV) Corrosion resistant performance Structure of aluminium fittings ZnO (Zinc Oxide).

ZnO varistros The resulting new varistor has resulted in Glass filled excellent energy handling and TOV epoxy laminate performance Bracket Disconnector ELD. Earth clamp LV MV. Low Voltage Surge Arresters Medium Voltage Surge Arresters Raychem 's Bowthorpe EMP surge arresters provide active over Raychem 's low voltage surge arresters provide voltage protection that contributes directly to improved reliability of protection for low-voltage overhead lines, consumer in- your system, reducing lost minutes and protecting expensive assets.

4 House supplies, distribution transformers and other systems. The gapless metal-oxide varistor incorporated Bowthorpe EMP DA silicone surge arresters have been designed and in the surge arrester reliably imposes low-value limits on tested to meet our customers demands with reliability and offering surges caused by atmospheric over voltages and improved operational performance. switching transients, thus protecting the insulation of the consumer-side networks and equipment. product Features The LV surge arresters are in compliance with Class II. Raychem 's Bowthorpe EMP: requirements as defined by IEC 61643-1. They are designed for applications in which protection against Tested in accordance with IEEE , 2005. direct contact is not necessary. Direct molded housing to prevent moisture ingress Low residual voltages High- energy handling product Features Safe non-shattering short circuit behavior to higher current levels Suitable for indoor and outdoor use Maintenance free Integrated disconnector Hydrophobic silicone/ EVA housing: (Tracking and erosion resistant).

5 Excellent cantilever and tensile performance Housing and lead is flame retardant and UV resistant Quality design and manufacturing meeting international standards Easy to identify failure indicator Raychem 's Bowthorpe OCP: Easy to install (no tools required). Raychem Bowthorpe OCP' silicone surge arresters have been Large selection of standard accessories designed and tested to meet our customers toughest environmental CE certified conditions and to meet the requirements of IEC60099-4. Our gapless zinc oxide polymeric arresters now have the OCP ranges builds on this experience and know how. Superior protection margins Applications .. Direct moulded housing to prevent moisture ingress Superior TOV performance Applications Motor protection Protects transformers and other Protects distribution assets equipments in station and distribution including transformers and systems against the damage caused by cable-end terminations from environmental (especially lightning lightning and switching surge Overhead line Service entry through effects) and operational conditions.

Raychem Polymeric Surge Arrester is High Voltage Surge Arresters WHY better than other Surge Arrester available in the market? Raychem Surge Arrester has been developed using the Each surge arrester module is completely knowledge accumulated over 35 years of internal materials impervious to the ingress of moisture and utilises the high mechanical strength properties of the science expertise and experience, resulting in a material with ZnO varistors bonded by cured resin impregnated excellent tracking and erosion resistance, and known for glass fibre. operating in the world's toughest environments. Raychem 's Surge Arrester is made product Features possible by: Direct bonding of housing to fittings ensures optimum moisture barrier Proven moisture sealing technology No air gap therefore no internal ionization All arrester cores are encapsulated in silicon insulating housing Light weight compared to porcelain Invisible interface prevents moisture from entering Ease of installation during severe thermal fluctuations due to normal Non shattering housing climatic and energy absorption events Optimised voltage stress grading eliminates need to oversize stress Polymer Housing grading ring.

7 Therefore the compact Non-tracking and hydrophobic silicon insulating series parallel can be installed in tight material is used spaces without infringing electrical or surge safety clearances Housing material has proven performance in long Superior TERT performance The diameter of the series parallel term TERT and UV aging tests and proven design has been calculated to reduce the resistance to flammability radial field stress to a minimum, even under adverse environmental conditions Fully integrated, single piece and void-less design Can directly be mounted on equipments Manufacturing integrates all components in a single piece Design is void and gap free ensuring peak performance under the harshest conditions Applications Disconnector (optional). Robust ground lead disconnector Reliable and consistent Safe short circuit failure Arc Furnace Offers operational reliability and consistency Transformers Transmission Can be shipped and stored restriction free Line Arresters Safe mode of failure Cable Terminations Substations Quality Manufacturing in ISO accredited production facility Perform 100% routine testing on arresters Excellent hydrophobicity Bowthorpe EMP Remote Surge Monitoring Systems with Current Leakage Measurement The Bowthorpe EMP surge counters use patented Planar Magnetic Current Sensing technology to accurately and reliably detect and measure current impulses.
