1. Product overview
KYN48A-12 metal armored withdrawn mid-mounted switchgear is a new development developed by our factory to widely absorb the advantages of similar products at home and abroad, and choose VE vacuum switchgear technology type of mid-mounted switchgear. It is currently the most advanced switchgear in China. Control, protect and monitor the circuit, this switchgear meets IEC298, GB3906, DL404 and other standards. 2. Product use KYN48A-12 metal armored withdrawn mid-mounted switchgear is used for 6~10 kV power distribution device as a single bus system to receive and distribute electric energy, and control the circuit Control, protection and monitoring. 3. Environmental conditions of product use (1) Ambient temperature: maximum temperature +40 °C, minimum temperature -10 °C (2) Ambient humidity: daily average relative humidity ≤95%, monthly average relative humidity ≤ 90% (3) Altitude: below 1000m (4) Seismic resistance: the earthquake intensity does not exceed 8 degrees (5) The surrounding air should be free from obvious pollution such as corrosive combustible gas and water vapor (6) There is no regular violent vibration place. The harsh design meets Class I requirements under harsh conditions. (7) When used under normal environmental conditions exceeding the provisions of GB3906, the user and our company shall negotiate.Name | Parameters |
