Solid insulation performance dị mfe: E na-enye advanced solid insulating materials dịka epoxy resin iji fully encapsulate internal high-voltage live components, na insulation strength dị mfe na-enye ike inwe electrical stress at 12kV or 24kV voltage levels. Na anya traditional insulation methods, enweghị ike inwe environmental factors dịka humidity, dust, and pollution, enweghị ike inwe risk of flashover and breakdown, na-enye long-term stable operation of the equipment in complex environments.
Compact and space-efficient design: Metal-enclosed structure bụ extremely compact with a small footprint, dị ka ọ ga-enwe ike inwe installation in space-constrained locations dịka urban distribution stations, commercial building switchrooms, and industrial park substations. By optimizing the internal layout, various functional modules are closely integrated, reducing installation space requirements while facilitating transportation and on-site installation and commissioning, thus improving the utilization efficiency of the site space.
Multiple safety protection mechanisms: Cabinet body na-enye fully enclosed metal shell, na-enye ike inwe shield the internal high-voltage electric field and prevent accidental electric shock to personnel. O na-enye complete internal mechanical and electrical interlocking devices to strictly prevent dangerous situations such as incorrect switching operations, on-load switching, and entry into live compartments. Some products are also equipped with live display devices to intuitively show the live status of the equipment in real-time, further ensuring the safety of operators and equipment.
Low maintenance and long service life: Solid insulating materials na-enye strong stability, and internal components are sealed in the metal shell, effectively isolating external erosion, reducing component aging and failures caused by environmental factors, and achieving long-term maintenance-free operation. Under normal circumstances, the service life of the equipment can reach 20 years or more, reducing the life-cycle maintenance costs and equipment replacement frequency, and providing users with reliable long-term investment returns.
Flexible power distribution adaptability: Supports multiple wiring methods such as ring network power supply and radial power supply, and can be easily connected with 12kV or 24kV transformers, cables, and other power equipment, flexibly adapting to different medium-voltage distribution network topologies. It can easily meet the needs of various power distribution scenarios, whether for urban power grid upgrading projects or complex power supply requirements in industrial plants.
Outstanding environmental performance: Different from SF6 gas-insulated ring main units, this equipment does not use SF6 gas, avoiding potential environmental hazards caused by SF6 gas leakage, and conforming to the current concept of green environmental protection. It is especially suitable for the construction of power distribution facilities in areas with strict environmental requirements, such as ecological protection zones and urban core areas.
