New integrated 600 A, 35 kV elbow surge arresters from Tyco Electronics protect underground cables and medium-voltage equipment from overvoltage surges from lightning and switching.
They combine gapless metal oxide varistor (MOV) technology into a fully shielded, fully submersible 600 A elbow configuration. The integrated arresters eliminate the need for bushing extenders and 200 A load break interface arresters. The elbow arresters use high-energy MOV blocks in a glass-filled epoxy laminate. The arresters will stay attached to the bushing during a fault, which enhances safety. The arresters are qualified to the latest revisions of IEEE C62.11 and 386. They are compatible with 600 A bushings meeting IEEE 386.
