Electric GW1-12 630A Isolation Knife Switch Outdoor High Voltage Disconnector MV&HV Knife Switch

Product Overview

The GW1-12LT outdoor high-voltage isolation switch is a double column vertical opening type, equipped with a manual operating mechanism of CS8-5D rainproof type and an electric operating mechanism of CX-6 type. This product is a three-phase common chassis knife switch, which can be divided into a chassis, insulators, and conductive parts. The chassis is composed of a frame welded with a rotating shaft, a bent plate, and angle steel. Six ceramic insulators are fixed on the chassis, with each two forming one pole. The rotating shaft is equipped with a three-phase operating insulator for operating the opening and closing movement of the three-phase knife switch. The conductive part is composed of a contact knife switch and a contact seat, which are compressed by a spring. When the switch is opened, the operating lever drives the rotating shaft to rotate, causing the operating insulator to push the switch upwards and separate the switch and the contact. The switch rotates around the contact seat, and the contact also moves upwards to the opening position under the driving of the switch. When closing, the operating lever drives the rotating shaft to rotate, causing the operating insulator to pull the switch blade and rotate downwards. After encountering the contact, it drives the contact to rotate and turn to the closing position together.
