Time-voltage
sectionalizers

TVS time - voltage sectionalizer (Autoself TM) is a control system, including the control cabinet and a disconnector or a load break switch. It can be connected to the most existing switch elements in the network. The Autoself has the same purpose as a recloser but utilizes a much simplier sectionalizing algorithm. The product's reliability has been proven for more than 30 years of operation in electrical distribution networks.

ACCESSORIES

MOUNTING BRACKET
FOR OVX & EOA501TVS

Hughes sectionalizer

This mounting bracket for OVX (left) is designed for 6/15 and 22/27kV models. The mounting bracket for EOA501TVS motor drive (right) is universal for all voltage classes. It fits on wood and concrete poles in the range of 180 to 250 mm. The bracket mounts on wood pole with a M20 through pole pin bolt and one wood screw. The upper hole is designed as a key hole for easy installation. Installation on concrete poles will be done by 4 x 25 mm stainless steel straps.
