M.O.V Shielded Sub-Surge Arrester

The CEE AKBLQ-H M.O.V shielded sub-surge arrester combines metal oxide varistor technology in a pre-molded rubber elbow to provide over-voltage system protection in an insulated, full shielded, submersible, dead-front device. It is typically used at the end point of a radial circuit or at the open point of a loop-feed circuit to provide surge protection in a more compact configuration. The M.O.V. shielded sub-surge arrester housing interface conforms to ANSI/IEEE 386 standard 386--Separable Insulated Connector System. The arrester housing is molded with high quality EPDM insulating material, when mated with a comparably rated product; it provides a fully shielded insulating connecter for energized operation. This M.O.V. shielded sub-surge arrester provides high voltage lighting and switching surge protection of transformers, cable, equipment and other components typically located on underground power distribution systems. Proper placement, voltage selection and coordination with riser pole arresters minimize damaging surge voltages by improving protective margins.
