GN24-12D Indoor High Voltage Isolator Switch

Product Overview

The GN24-12D(I, II) and GN24-12D(I, II)C series indoor high-voltage isolating switches are indoor devices with a rated voltage of 12 kV and a three-phase AC frequency of 50 Hz. They adopt purple copper knife switches with excellent electrical conductivity and low resistance, and the purple copper is tinned to prevent oxidation. The support undergoes spray molding treatment, which is corrosion-resistant, exquisitely crafted, and durable. It is also equipped with high-strength resin insulators and high-quality silver contact micro switches, ensuring stable performance and a long service life. The product is diversified and supports customization; it can be customized according to drawings to meet the needs of different customers.

Structural Forms

a. The GN24-12D(I 1, 2; II 1, 2) Q-type isolating switch has a grounding form on the side of the moving (or stationary) contact. The main blade and the grounding blade are combined on an integral frame. Type 1 is operated on the left side, and Type 2 is operated on the right side. The Q-type is a product suitable for all working conditions and can be equipped with a live-line display device according to the user's ordering requirements.b. The GN24-12SDI, II (C1, 2, 3) type isolating switch has a grounding form on both the moving and stationary contact sides. The moving (or stationary) contact side can be changed into a wall bushing; or both sides can be changed into wall bushings. The main blade and two sets of grounding blades are combined on the same frame. One set of grounding blades can be operated independently, or they can be operated simultaneously by one operating mechanism.
