20kv Distribution Transformer

Product overview

This product has the performance ofo-load loss, low no-load current and low noise. It improves the quality of voltage and the reliability of power supply, and is a green energy-saving equipment that is beneficial to the environment

The company produces s13-mrl, s11-mrl, series of fully sealed three-dimensional three-phase coil core transformer different from the traditional planar laminated core transformer. The iron core is composed of three-phase column rail arranged hree-dimensional triangle. Each cylinder is made of high quality cold rail silicon copper thin strip continuous winding, the bandwidth is made straight line or curve shear by numerical control mate itter. the belt material is wound in the core coiler to form a nearly circular or flanged circular arc plate and then processed by vacuum nitrogen filling annealing to eliminate pro cessing stress, character reorientation, improve magnetic permeability, improve electromagnetic performance; The high and low pressure coil is directly wound on the paper sheet of the core pillar with a special winding machine. The overall structure is solid and compact. The upper and lower rail insulation and laminate wood are adopted for the body

Types of meaning

Product features

According to the current international GB/T6451-2015 three-phIl-immersed power transformer technical parameters and requirements, capacity 30-1600kva, S13-mrl series no-load loss decreases 50% on average, and load loss decreases 30% on average, S11-mrl series no-load loss decreases 30% on average, and load loss decreases 25% on average

Low no- load current

According to the current national standard GB/T6451-2015, the no-load current of s13-mrl series decreases by 75% on average, and the no-load current of s11-mri series decreases by 75% on average

Low operating noise

According to the noise standard of JB/T10088-2008, the noise of S13-MR L and S11-MRL series were reduced by about 79db

Strong short circuit resistance

The transformer body is in the shape of three-dimensional prism, and the tension screw is set around and in the center mhich is integrated with the insulation and laminated wood of the upper and lower rails, and can effectively resist the axial and dial mechanical stress in case of sudden short circuit
