Product introduction
Gas Insulated Switchgear is an integrated power distribution equipment with sulfur hexafluoride (SF6) gas as the insulating medium. It is different from traditional air-insulated switchgear. The core components of the main circuit are fully sealed and integrated inside the metal cabinet. The equipment has a compact structure, high safety, and comes with intelligent monitoring function, which is suitable for 12kV-35kV medium voltage distribution field scenarios. At the same time, it supports flexible installation and personalized customization, stable operation and strong compliance, and is widely used in various power projects such as urban power distribution, high-rise buildings, data centers, hospitals and industrial parks.
Core Advantages of The Product
High space utilization rate: The compact sealed structure is adopted, which can save 70% of the installation space compared to traditional switchgear, effectively solving the installation problems of urban substations, underground power distribution rooms, equipment mezzanine and other space-restricted scenes, and the on-site arrangement is more concise.
Excellent safety and fire resistance: it is vacuum-cast and encapsulated with H-grade high-temperature-resistant insulation materials and F1-grade flame-retardant epoxy resin, and the equipment is oil-free and leak-proof. It has passed a number of international safety tests, has low partial discharge, no risk of fire or explosion, and is suitable for all kinds of places with high fire protection requirements.
Low-noise and high-efficiency heat dissipation: the standard natural air-cooling system can quickly dissipate heat without additional energy consumption, and intelligent forced air cooling can be switched under heavy-duty conditions. With shock absorption and noise reduction structure, the operating noise is low, in line with the national standard and IEC noise standards, and there is no noise pollution.
Intelligent operation and maintenance, flexible installation: equipped with an intelligent gas monitoring system, it can monitor temperature and gas density in real time, support automatic alarm and remote monitoring, and greatly reduce manual inspection pressure. Support a variety of installation methods, voltage, current, protection level and other parameters can be customized according to project needs, and the adaptability is extremely strong.
Stable and durable quality: the equipment technology is mature, the service life can reach 25-30 years, the average annual failure rate is extremely low, and it is equipped with perfect quality assurance and one-stop pre-sales, installation, and after-sales maintenance services, making the use of the project more worry-free.
Product Use Environment
The temperature range is widely adapted
The equipment can operate stably in a wide temperature environment from -25℃ to 40℃, and there will be no performance attenuation in extreme high and low temperature weather, and it is suitable for outdoor and indoor working conditions in most areas.
Strong protection and corrosion resistance
Fully sealed metal cabinet design, up to IP44 protection level, can effectively resist dust, moisture, salt spray erosion, and is suitable for harsh environments such as coastal high-humidity areas and dusty industrial parks.
Good adaptability at high altitudes
It can operate stably in plateau areas of 4500 meters and below, solve the problems of easy discharge and poor adaptability of traditional switchgear at high altitudes, and meet the long-term stable power supply needs of complex projects.
