Three Phase Dry Type Distribution Transformer 30 - 3000kva Rated Capacity

Product Description

66kV Oil-Immersed Transformer Three-phase Dual-winding Voltage

Regulating Power Transformer without Excitation

Product Introduction

This product performance is low dissipation,good energy saving effect and economic operation,free maintenance.In addition to the process of advanced structure,short circuit,high level of lightning shock resistance,also has a resistance,moisture,dust,low noise characteristics,can be further load center.Being widely used in high-rise buildings,airport,station,whart,power plants,substations,ect.Especially suitable for installing on the places where inflammable and explosive fire prevention requirement high.

control systom.

Structure

High Electrical Strength, the use of glass fiber grid plate inside and outside the winding,

increase the mechanical strength of the coil, improve the ability of anti-short circuit products

. Good thermal stability coil, lead using copper wire, in the coil to add axial oil channel, leaving

a full margin of temperature rise, strictly control the heating part and the most hot spot

temperature rise, the main temperature rise index of the products is at least 5 degrees lower

than the international. flame-retardant and explosion-proof, high-voltage winding with copper

wire, low-voltage winding with copper wire or copper foil, glass fiber and felt filled and wrapped,

in vacuum, with epoxy without Filler, solidified to form a solid cylinder, flame-retardant and

explosion-proof. Low temperature rise, long service life, low temperature rise, strong heat

dissipation, in forced air cooling conditions can run 150% rated load. Optional Temperature

Control Protection System with perfect performance provides reliable guarantee for safe

operation of transformer and transformer. High reliability, intelligent temperature controller

for temperature control, easy maintenance, improved transformer, safe and reliable operation.

Maintenance-free, dry-type transformer without oil, do not need to regularly change the oil and

other maintenance products. Beautiful appearance, the core column of the product is tied

with Grade F weft-free tape, and the surface of the clamp and fastener is specially treated to

make the product more beautiful.
