JMB20KVASafety Lighting Transformer for Building Construction

JMB portable lighting safety transformer is suitable for circuits with AC 50Hz and voltage of 1500V and below.It is used as thelocal lighting power supply for machinetoolsand other equipment.

It is composed of BKseries transformer and protective shell.There are terminals for input power supply and load wiring on both sides of the shell and grounding

screws for grounding;It is a safe isolation step-down transformer.Because the "traveling crane"in the factory is a metal frame,when workers work on the traveling crane,if they usehigh-voltage lighting lamps,leakage is easy tocause

casualties.Therefore,the safety voltage of 36V and below is used aslighting power on the traveling crane.JMB portable lamp transformer is a safety isolation transformer that converts 220V or 380VAC into 36V and below safety voltage

through the transformer for local lighting It is generally converted into 12V,24V,36V,etc.itis mainly used in low-voltage power supplyoccasions,such as local lighting in factory production lines and site dormitories.

1.Scientific and reasonable design canwork effectively inthe rated load for a long time.

2.It is made of high-quality new siliconsteel sheet to effectively reduce iron loss and improve conversion efficiency. 3.It is wound with high temperature resistant high-quality wire to reduce the loss of the transformer,and soaked in   insulating paint fordrying.

4.H-class insulation material and high-temperature resistant DMD insulation materialare adopted to improve the high- voltage strength,insulation grade and prolong the servicelife.

5.Patented   design,beautiful   and   novel,high   power   density,smallvolume   and   high   space   utilization   rate.
