Description

S**-M. RL, Three Phase Distribution Transformer with three-dimensional wound core is a new type hi-tech and high energy-saving product. Compared with series S9, *0% of no-load current and ****0% of no-load loss can be decreased, ***3dB in noise level can be reduced. It is applicable for distribution, power supply and lighting in industrial, agricultural, mineral, petrochemical fields. Normal service condition: Elevation height less than ***0m Environmental temperature Max. Temperature **0 oC Max. Daily average temperature: **0 oC Max. Annual average temperature **0 oC Min. Temperature **0 oC Operation environment outdoor Symmetry of multi-phase power source Three-phase power sources shall be almost symmetrical. Feature: 1. Three-dimensional wound core consists of three core limbs whose cross-section is close to circle. Magnetic circuit in three phase is totally symmetrical and identical, which shortens the yokes but makes factor of core limb bigger. 2. After annealing, internal stress can be removed thoroughly for three-dimensional wound core. There is no higher magnetic reluctance everywhere in its circuit, so no-load loss and energizing current can be decreased greatly. The test shows that more than *0% of no-load current and ****0% of no-load loss can be decreased. 3. Only fewer joint caused by continuous wound core, there should no noise occurred due to the blocking inside the magnetic circuit of stacking core. In such way, ***3dB in noise level can be reduced, which is almost in the state of noise silence. 4. Triangle tank is used for such transformer so it is smaller than the normal one. In a word, it is impact, small size with artistic appearance
