HV Insulation Components

    CYLINDER

Cylinders are made of ENPAYBOARD® and are used as support of the windings in Power Transformers.

ENPAY offers cylinders with or without dimensional stabilization depending on the customer preference. Cylinders can be produced in the form of open or glued types and are mechanically strong and electrically reliable which are used to form a barrier inside the windings of Transformer. 


 

    INSULATION KITS

ENPAY offers Insulation Kits which allows for optimization of the assembly cost of Power Transformers. Various forms of Insulation Kits are available at ENPAY offering less assembly time and lower production cost to Power Transformer Producers.



    SHIELD CYLINDER

Shield cylinder smooths peaks of electrical field occured around the transformer cores or between winding coils of power transformers.

 

 

    CAPS AND ANGLE RINGS

Caps and Angle Rings are produced from wet material by machine moulded method and they are used as a barrier at the end of the transformer windings.

Various diameters of caps and angle rings are available depending on customer’s specifications.

 

 

    SNOUTS, CHIMNEY SECTORS AND FLANGE TUBES

ENPAY offers tailor-made solutions in order to insulate the lead out of the windings. These products are used so as to isolate the terminal leads of transformer winding. They are final insulation components in the power transformers, regulates the electrostatic fields existing in the terminal leads and enable the transformer to work reliably.

These products are manufactured in the form of wet moulding method and customized solutions are available.

 

 

    EDGE PROTECTIONS

Edge protections are protective components commonly used between or over windings to cover winding edges.

These products are produced from either wet material or ENPAYBOARD®.

 

 

    END (CLAMPING) RINGS

End rings which can be manufactured from ENPAYBOARD® or ENPAY Laminated Pressboard are offered in various types to withstand against axial and radial forces in transformer.

 

 

    PRESS RINGS

Press rings can be produced as tailor made and have the function of clamping by applying pressure on the winding of transformer.

  

 

    SHIELD RINGS

Shield rings distribute the electrical field gradient over the top and bottom ends of power transformer windings and smooth the peak values of electrical field to the lower levels.

 

 

    SHIELD END RINGS

Shield end rings are used to smooth the electrical field at the ends of spiral windings and support the winding in axial direction.

 

 

    STRIPS 

Strips supported with cylindrical barriers have the function of radial spacing between different voltage level of windings in power transformers as well as supporting the outer barriers and kit packages mechanically. Strips well compatible with radial spacers offers a good guide for winding layers.

 

 

    SPACERS

Spacers with various channel geometries can be produced exactly compatible with trapezoid, rectangular or T-shaped strips facilitating a splendid separation of winding layers.

 

 

    CLACKBANDS AND TOOTHBAND

Clackbands and toothbands form a good duct for oil flow between winding layers. These products are produced by combining layers of insulation paper and small rectangular/trapezoid blocks chamfered at corners and made of ENPAYBOARD®.
