Product Overview
35kV series transformers are with the following characteristics,low loss, low noise, protection against thunder and lightninghigh short-circuit withstand capacity and beautiful appearanceetc. it is made by advanced assembling lines and methodwith qualified and refined accessories. it enjoys four remotefunctions."remote communication remote test,remoteadjustment and remote control". By remote control from acomputer, the power station could be free from supervisionin the office. 35kV series energy saving transformers havepassed the identification Test by State Bureau of Machinerylndustry, and State Power Corporation.
35kV series transformers are mainly used in urban and ruralpower grids and other industrial, mining enterprises,poweltransmission and distribution industry and also agricultureprojects.
The core is processed by advanced vertical cut, horizontalcut, and stacking with stepped lap core and grade 3 seamsit disperses the air distribution, improves flux trend, thus,anddecreases the no-load loss, no-load current and noise
The core uses particular adhesive for the plate, press ringand silicon steel surface; and a range of overall structureand measures are used to increase the mechanical strength
New structure of HV, LV windings and reasonable layoutof oil duct and connecting area increases the capacity ofmechanical strength and short-circuit withstand capacity
The tank is bell type or core-lifting type, and the tank side isas corrugated form, with flowing lines, simplicity and beauty.
