Product Description
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/T17467-1998 and we adopt standard of IEC1330-1995 for parameter. At the same time, we partly refer to standard of JB/T10217”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 300A, thermal stable current is 12.5kA/2S, dynamic stable current is 31.5kA, short-circuit closing current is 31.5kA, power frequency withstand voltage is 42kV, impulse withstand voltage is 75kV, on-load operation number is 100, mechanic operation number is more than 2000. For transformer of circular net type, rated on-load current is 600A, thermal stable current is 16kA/2S, dynamic stable current is 40kA, short-circuit closing current is 40kA, power frequency withstand voltage is 42kV, impulse withstand voltage is 75kV, on-load operation number is 100, mechanic operation number is more than 2000. For plug fuse and back-up fuse, we also use products from Cooper. For 400kVA padmounted transformer, we use B-O-N-40A; B-O-N-50A for 500kVA; B-O-N-65A for 630kVA; B-O-N-80A for 800kVA. 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. CJ19 contactor is used. We use whole-tight energy-saving transformers of S11 and its no-load loss is lower than that of oil-dipped transformers of SB10. High voltage 10±2×2.5%kV. Low voltage 00V/230V.
