비정질 합금 3차원 권선 철심 분배 변압기

SBH25-M·RL-200/10-NX1
This product is the SZBH13, SZBH21, and SZBH25 new energy efficiency series Class I energy efficiency amorphous alloy three-dimensional wound core wide-range on-load tap-changer distribution transformer, independently developed and designed by TBEA. Its function is to enhance the power quality in low-voltage areas of the power grid. This product combines the advantages of amorphous three-dimensional wound cores and is the first high-end distribution network product to adopt an independent oil chamber vacuum on-load tap-changer, applied to low-voltage management.

Product advantages
Low loss.
There is little harmonic influence.
The transformer is free from core lifting and maintenance.
Low noise.
Application Scenarios
This product can be widely applied to urban and rural distribution networks and other regions.
