110KV Power Transformers

110KV-Power-Transformers Product Description110KV Power Transformer has the features of low-noise, low-partial discharge, low-temperature rise, shock-resistance, short-circuit resistance, no lcakage and attractive appearance.Power-TransformersTechnical Parameters 1. 6300 120000KVA Two-winding Transformer Fitted Low-noise with On-load On-load Tap-changer 2. Rated Capacity (KVA): 6300 120000 KVA 3.Vecor Group: Ynd11 4.Impedance Voltage (%): 10.5% 5.Rated voltage: H. V.: 110, 121 KV (Or as customer requirement) 6.L. V.: 10.5, 11,33 KV (Or as customer requirement) 7.Tapping range: +/- 5% or +/- 2 * 2.5% (Or as customer requirement) 8.Frequency: 50Hz 9.Number of phases: 3 10.Cooling method: ONAN or ONFN 11.Temperature rise limits: Winding ≤ 65K 12.Top oil ≤ 60K 13.Standards: GB1094 Power transformer 14.GB/T6451 Technical data & requirement of three-phase oil immersed power transformer 15.IEC60076 Power transformerService conditions 1.The height above the sea level is below 1000m; 2.Ambient temperature: 3.Highest air temperature +40º C; 4.Highest daily average air temperature+30º C; 5.Highest annual average air temperature +20º C; 6.Lowest outdoor air temperature -25º C;Scope of application 1.Cooling and auxiliary equipment 2.Generally, it is ONAF/ONAN type, when ONAF, it runs with full load; When ONAN, the load is running 67% of the full load. 3.The radiator is flake type, the seam between the flakes is welded. 4.The open and close of the fan motor are controlled by oil temperature and olad, The controlling apparatus is attached on the transformer. 5.The conservator is in capsule type. There is oil-resisance, high temperature proof, air-sealed capsule to insulate the oil and the outside air, so that oil is outside the capsule and air is inside the capsule. In order to improve the stability of the transformer, the air room of the capsule closes the outside air through silicongel
