Product description

Product features of 1000KVA dry-type transformer

1. Low loss, good power-saving effect, bringing economic benefits to operation.

2. Flame retardant, explosion-proof, pollution-free, maintenance-free, can be dispersed and installed in the load center, reducing investment cost and saving costs.

3. The partial discharge amount is less than 10PC, the coil does not absorb moisture, does not absorb dust, has high mechanical strength and good reliability.

4. Anti-short circuit, good resistance to lightning impact.

5. The shell is made of three materials: stainless steel, cold plate and aluminum alloy, the type is divided into wind type and heat dissipation type, and the inlet and outlet lines can be up and down, down and out, and down and down.

6. The transformer can be equipped with temperature control and temperature display system according to user needs, and can be used with temperature control system. Sales Hotline: 13508930968

1000KVA dry-type transformer structure features:

1. Iron core

The 1000KVA dry-type transformer adopts high-quality cold-rolled grain-oriented silicon steel sheet, and the iron-core silicon steel sheet adopts a 45-degree full miter joint, so that the magnetic flux passes through the direction of the silicon steel sheet joint.

2. Winding

1000KVA dry-type transformer windings are as follows:

(1) 缠绕式

(2) Epoxy resin and quartz sand filling and pouring

(3) Glass fiber reinforced epoxy casting (i.e., thin insulating structure)

(4) Multi-strand glass filament impregnated epoxy resin winding type

3. High voltage winding

1000KVA dry-type transformer generally adopts multi-layer cylindrical or multi-layer segmented structure

4. Low-voltage winding

The 1000KVA dry-type transformer generally adopts a layer or foil structure.

1000KVA dry-type transformer environment: indoor use
