Product Introduction
Our company has adopted high-quality materials and advanced process technology to produce SBK-SG series three-phase line type transformer for years. This series transformer can be inserted into the load center, which is mainly used in various power supply locations with AC 50/60HZ, voltage not surpass 500V. Allocation of various input, output voltage, joint groups, and tap line group capacity can be designed and made according to user requirements. Moreover, it has advantages of fireproof, anti-moisture, safety and reliability, energy save and convenient maintenance.
Application
It can be widely used in subway, high-rise buildings, airports, stations, printing, CNC, dock , power distribution and transmission of industrial and mining enterprises and tunnel and usage of imported equipment.
