Product Introduction

GW4-126 Outdoor High Voltage Isolating Switch is a 3-phase AC high-voltage electrical appliance, used in power systems with a voltage of 40.5, for no-load switching in high-voltage lines, and for electrical isolation between high-voltage busbars, circuit breakers and other electrical equipment under maintenance and energized high-voltage lines.

Product Structure

GW4-126 Outdoor High Voltage Isolating Switch is double-column horizontal rotation. It includes 3 single poles, each pole is a double-column structure, mainly composed of a base and a support insulator. Each pole consists of 2 insulators, which are respectively installed on the bearing seats at both ends and connected by cross-links. It can rotate horizontally within a range of 90°. The conductive part is divided into two halves, which are respectively fixed on the insulator pillars, and the contact is in the middle of the two porcelain pillars. When the mechanism is in motion, one of the pillar insulators rotates 90°, and the other insulating pillar also rotates 90° at the same time due to the connecting rod transmission, and the switch is opened and closed on the same side. In order to ensure the correct operation sequence between the disconnector and the grounding switch, reliable mechanical and electrical interlocking devices are installed on the product and mechanism.

Product type

GW4-126 Outdoor High Voltage Isolating Switch have 3 types :

1. Ordinary type, pollution-resistant type, plateau type

2. Electric operation, manual operation

3. Ungrounded, single grounded, double groundedis
