Description

Padmounted Transformer (American Style Packaged Substation) Padmounted transformer of ZB series is widely used high buildings, residence community, industrial park, shopping center, air and sea port, school, industry and mining enterprises. The product complies to standard of GB/T*********8 and we adopt standard of IEC********5 for parameter. At the same time, we partly refer to standard of JB/T****7”Padmounted transformer”. The product has characteristics of strong distributing capability, low noise, low loss, small volume, compacted structure and easy installation and maintenance. For load switches, we use product from Cooper of America. For end-type transformers, rated on-load current is **0A, thermal stable current is *2.5kA/2S, dynamic stable current is *1.5kA, short-circuit closing current is *1.5kA, power frequency withstand voltage is *2kV, impulse withstand voltage is *5kV, on-load operation number is **0, mechanic operation number is more than ***0. For transformer of circular net type, rated on-load current is **0A, thermal stable current is *6kA/2S, dynamic stable current is *0kA, short-circuit closing current is *0kA, power frequency withstand voltage is *2kV, impulse withstand voltage is *5kV, on-load operation number is **0, mechanic operation number is more than ***0. For plug fuse and back-up fuse, we also use products from Cooper. For **0kVA padmounted transformer, we use B-O-N**0A; B-O-N**0A for **0kVA; B-O-N**5A for **0kVA; B-O-N**0A for **0kVA. In low voltage part, for main switches, we use OETL isolating switches which are imported ABB. For branch switches, we use S5N from ABB Beijing. Capacitor compensation is automatically done. CJ*9 contactor is used. We use whole-tight energy-saving transformers of S*1 and its no-load loss is lower than that of oil-dipped transformers of SB*0. High voltage *0±2×2.5%kV. Low voltage *0V/**0V.
