Three Phase Isolation Transformer By Shenzhen Wapower Electrical Technology Co., Ltd.

With a sole aim in delivering quality products, we are the prominent Exporter, Manufacturer & Supplier of Three Phase Isolation Transformer in Shenzhen, Guangdong, China. Three phase isolation transformer is mainly used in low voltage distribution system, isolating load from power supply. Distribution system is divided into TN, TT and IT. The first T indicates that the neutral point of power transformer is directly grounded. I indicates the neutral point of power transformer is non-grounded(or grounded through high impedance). The second T indicates that the case of electrical equipment is directly grounded, but have no connection with the power grid of ground system. And N indicates that the case of electrical equipment is connected with the grounded neutral wire of system.

IT system: the neutral point of power transformer is non-grounded but the case of equipment adopts protection grounding.

Technical parameters:
1, Power range a 1600KVA
2, Dielectric strength: winding-winding, winding-earth 3000VAC / 50Hz / 60s no arcing or breakdown
3, Insulation resistance: cross-core screw rob - earth 500VDC, insulation resistance value a Y100MIC
4, Noise level < 65 db (The testing point's horizontal distance from transformer should be 1 metre.)
5, Protection grade: IP00
6, Insulation class: H
