Product Description

The outer casing and the like can be carefully designed and manufacturedaccording to the requirements of the user.The winding adopts the method of winding out of the whole row, thetransformer is vacuum-impregnated,so that the insulation grade of thetransformer reaches F grade or H grade, and the product performancereaches the advanced level at home and abroad. QSG/SG series three-phase dry isolation transformer is widely used incircuits with Ac 50Hz to 60Hz and voltage below 2000v.

Product Features

Electrical Isolation​: It realizes electrical isolation between the primary and secondary sides through electromagnetic induction. This effectively cuts off the direct electrical connection between electrical systems, preventing the spread of electrical interference and faults, and enhancing the safety and stability of the power system.
Fire – proof and Moisture – proof​: The windings are made of non – flammable insulating materials, and the structure is designed for good heat dissipation and moisture resistance. Compared with oil – immersed transformers, it greatly reduces the fire risk, making it suitable for places with high fire – prevention requirements.
No Oil Pollution​: There is no oil inside, avoiding environmental pollution caused by oil leakage. Also, it reduces the oil – handling process in maintenance, which is environmentally friendly and convenient for installation and maintenance.
