Product Introduction

The LXG-40.5 type gas insulated metal-enclosed switchgear is suitable for power transmission and distribution in new energy power generation fields, compact secondary substations, commercial buildings, rail transit, underground substations, and remote area substations, especially for installation in places with limited space. The product adopts a design concept of high performance and miniaturization, with full SF6 gas insulation. Equipment operation is independent of the external environment, such as high altitude, salt spray, condensation, dust, humidity, and other climates, truly achieving maintenance-free and highly reliable applications to meet the needs of various power users.

Product Features:

·Comprehensive functions, compact and flexible, convenient for installation in space-constrained areas such as wind towers.

·Modular design, can be combined and expanded arbitrarily, and can realize splicing and replacement inside wind towers.

·Gas tanks of switchgear are factory-assembled and transported as a whole. Reliable busbar connectors are used for cabinet combination, and no on-site insulation gas handling is required.

·All high-voltage live parts are sealed in a grounded 3mm stainless steel gas tank, effectively ensuring personal safety of operators.

·The gas tank filling pressure is as low as 0.02MPa (relative value, 20°C). Rated insulation level and breaking capacity are guaranteed at zero gauge pressure to ensure power supply reliability.

·High-quality stainless steel gas tank with full laser welding, with an annual gas leakage rate of less than 0.05%.

·Solid interface plug-in technology, using fully shielded high-voltage components for safe and reliable operation.
