Onload Tap Changer Distribution Transformer
The performance of Farady SZ-M series SZ series 10KV and 35KV load ratio voltage transformer conform to the standard of GB 1094 and IEC 60076 ,the products are widely used in power transmission and distribution of indusrtrial and agricultural power networks ,because of the unstably of power supply.
- Load-ratio voltage regulation,
- high reliability,
- advanced level of performances,
- reasonable economical indictors
- The core joints are of stepped shape with 3 steps ,and the surface of the core is coated with cured paint to lower loss and noise
- a) Suitable for indoor or outdoor application
b)Air temperature: Maximum temperature: +40℃; Minimum temperature:-30℃
- c) Humidity: Monthly average humidity 95%; Daily average humidity 90% .
- d) Altitude above sea level: Maximum installation altitude: 2000m.
e)Max wind speed:35M/s
- f) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
- g) No frequent violent shake
Note: * Beyond those services condition should enquiry to manufacturer technical dept during order
