Introduction
A: Product Overview
The XGN2-12 Box Type Fixed Metal-Enclosed Switchgear is a robust, standards-compliant solution designed for reliable power distribution in 3.6–12kV, 50Hz three-phase AC systems. Built to handle rated currents from 630A to 3150A, it supports single busbar, double busbar, and single busbar bypass configurations, making it versatile for power plants, substations, and industrial mining facilities.
Manufactured in compliance with IEC 60298, GB3906, DL/T402, and DL/T404 standards, this switchgear meets the strict “five-proof” interlock requirements to prevent misoperation and ensure maximum safety for personnel and equipment. Its high short-circuit performance, with rated breaking currents up to 40kA and withstand currents up to 100kA peak, delivers dependable protection against overloads and faults. The design also ensures superior insulation strength, with power frequency withstand voltages of 24/32/42kV and lightning impulse withstand voltages of 40/60/75kV, guaranteeing stable operation under harsh electrical conditions.
Compact and practical, the XGN2-12 features a footprint of 1100×1200×2650mm and a weight of approximately 700kg, ideal for space-constrained indoor substations. It supports both electromagnetic and spring energy storage operating mechanisms, offering flexible control options for diverse system needs. With an IP2X protection rating, it operates safely at altitudes up to 1000m, within temperatures of -15°C to +40°C, and in environments free from corrosive or flammable gases.
Key advantages include its simple and reliable fixed structure, which minimizes maintenance needs and reduces long-term operational costs. The switchgear is engineered for easy installation and straightforward maintenance, with accessible components that simplify routine inspections and repairs. Engineered for low maintenance and long service life, this fixed metal-enclosed switchgear provides a cost-effective, reliable choice for medium-voltage power distribution projects worldwide.
