Raychem MV Outdoor Surge Arresters - Yakir …

1 Raychem MV Outdoor Surge 113/05/14 16:03 Raychem pioneered the developmentof polymeric housed Surge Arresters in the early 1980 s and since 1986 have a proven service experience across the globe, operating in the worlds toughest HDA Ethyl Vinyl Acetate (EVA) Surge arrestershave been designed and tested tomeet our customers toughest environ-mental conditions and to meet therequirements of IEC60099-4. The final HDA qualifications are performed by an independent laboratory in is the latest gapless, zinc oxidearrester family from the core of the Raychem HDAdesign is our improved ZnO varistordisk, which has superior thermal andelectrical characteristics and new varistor and HDA design combination results in superior energy handling and TOV crimped structural constructionoffers a light weight product withoptimal mechanical manufacturing process ensuresvoid free construction and optimuminterface sealing.

2 This is achieved bybonding the EVA housing directlyto the ZnO discs and aluminiumfittings using a Raychem proprietarybonding of our new hydrophobicEVA HDA design are: Alternating sheds for superior pollution flash over resistance Superior TERT performance Constant voltage: , >360min - Stepped voltage: >300min - All eventual failures by erosion only, ie no tracking in step voltage test Housing tested to IEC 1000hr salt fog testExcellent hydrophobicitySafe non-shattering failure modeSuperior TERT performanceThe construction of the HDA design comprises of:1 ZnO, (Zinc Oxide) varistors 2 Raychem HDA proprietary EVA housing3 Flame retardant FRP structure4 Corrosion resistant aluminium fittings MV Outdoor Surge ArrestersBenefits Superior TOV performance Safe, non-shattering failure in the short circuit test by pre-failing to higher fault currents High energy handling capability Tested in accordance with IEC60099-4 Superior protection margins Direct molded housing to prevent moisture ingress Safe non-shattering short circuit behavior to higher current levels Maintenance free Hydrophobic EVA housing Excellent cantilever and tensile performance Excellent mechanical.
