Product Description:
Dry transformer is mainly applied to heating furnace such as glass furnace, electric resistance furnace, vacuum furnace, polycrystalline furnace and electroplate, traction rectifier transformer for first grade.
1. Copper conductor is used both for H. V. &L. V. Coils to strengthen the glass fiber. It is dried and cast by epoxy resin under the high vacuum. After curing, it is a firm cylinder with high mechanical strength and withstanding short-circuit capability, which is smaller to partial discharge, higher reliability as well as long service life.
2. Accordingly the imported epoxy resin and glass fiber compound insulation, materials are used and certain silicon powder is contained in the epoxy resin. Both heat conduction co-efficient and flameproof ability is greatly improved in comparison with old type materials. There would be no toxin and harmful gas caused by resin under high temperature.
3. The moist cannot be absorbed by coils. As the result of that the core clamp is coated with the special anti-corrosive materials, it can do as usual under the severe conditions. It is unnecessary to get rid of moisture for interval operation.
4. Excellent capabilities of withstanding short-circuit and lightning impulse.
5. Good heating dissipation due to thin resin coated on the outside of coils. Normally, natural air cooling (AN) is taken. Fan cooling system could be provided with the transformer in any protection grade to improve short time overload ability and ensure the safe operation.
Cast Resin Dry Type Transformer, Low Noise, Low Loss and Low Partial Discharge.

Circuit breakers shall be designed and carried out so that, in normal use, they guarantee a reliable operation without any danger to the user.

Circuit breakers are intended for a projecting assembly and fixing by screws on plastic or wooden board, and planned for possible fixing on DIN type rail.

Circuit breakers are intended for outdoor transformer protection so they should be supplied in a plastic self- extinguishing weather proof lockable boxes. The cable entry points on the boxes should be on bottom side of the boxes. Bidders should provide pictorial - drawings of the boxes.

For single-phase circuit breakers (1 phase and 1 neutral), breaking action shall be bipolar despite only one pole and/or both is protected. For the three-phase circuit breakers breaking action shall be 4-pole tripping despite protection on 3 poles only.

The apparatus includes:

  • A self-extinguishing insulating matter case (“boitier”) with sealable terminal cap designed in one or two pieces.
  • Design of the electric terminals shall be such as: even with removed case or terminal caps, it will not be possible for a user to touch inadvertently the live parts.
  • A mechanism with free release ensuring the hand drive operation (switching operation) and the automatic tripping in the event of default (overload and short-circuit.
