Product descriptions from the supplier
The DNQ8 automatic transfer switch (ATSE) is a switch that integrates switch and logical thinking to truly realize electromechanical integration. It has the functions of voltage detection, communication interface, electrical and mechanical interlocking. It also can realize automatic, manual, remote control and emergency manual control. It is applicable to the automatic conversion of the main power supply and standby power supply of the power supply system or the automatic conversion and safety isolation of two load devices.
The operation is realized by the logic controller managing the operation of the motor and gearbox with various logic commands. The motor drives the energy storage spring to release instantaneously.

How Does Oil Loss Affect SF6 Relay Performance?1.SF6 Electrical Equipment and the Common Problem of Oil Leakage in SF6 Density RelaysSF6 electrical equipment is now widely used in power utilities and industrial enterprises, significantly advancing the development of the power industry. The arc-quenching and insulating medium in such equipment is sulfur hexafluoride (SF6) gas, which must not leak. Any leakage compromises the reliable and safe operation of the equipment, making it essential to monitor the SF6 gas density. Currently, mechanicalFelix Spark10/21/2025 -
MVDC: Future of Efficient, Sustainable Power GridsThe Global Energy Landscape Is Undergoing a Fundamental Transformation toward a "fully electrified society," characterized by widespread carbon-neutral energy and the electrification of industry, transportation, and residential loads.In today’s context of high copper prices, critical mineral conflicts, and congested AC power grids, Medium-Voltage Direct Current (MVDC) systems can overcome many limitations of traditional AC networks.

Grounding Causes of Cable Lines and the Principles of Incident HandlingOur 220 kV substation is located far from the urban center in a remote area, surrounded primarily by industrial zones such as Lanshan, Hebin, and Tasha Industrial Parks. Major high-load consumers in these zones—including silicon carbide, ferroalloy, and calcium carbide plants—account for approximately 83.87% of our bureau’s total load. The substation operates at voltage levels of 220 kV, 110 kV, and 35 kV.The 35 kV low-voltage side mainly supplies feeders to ferroalloy and silicon carbide plantsFelix Spark10/21/2025 -
Overhead Power Lines & Towers: Types, Design & SafetyBesides ultra-high voltage AC substations, what we encounter more frequently are power transmission and distribution lines. Tall towers carry conductors that leap across mountains and seas, stretching into the distance before reaching cities and villages.

How to Install MPP Pipes Without Excavation: Full GuideI. Management Regulations for Trenchless Construction of MPP Power ConduitsIn power engineering, cable installation often employs trenchless techniques such as "pulling pipe" or "pipe jacking" due to routing constraints, construction schedules, and other objective factors. While trenchless methods offer advantages like minimal traffic disruption and shorter construction periods, they also present safety and management challenges. This is because trenchless technology remains relatively new for pEncyclopedia10/21/2025
