Epoxy Resin Vacuum (Pressure) Casting Equipment for Mold Cast Coils of Dry Type Transformers

Description

This equipment is special for epoxy resin casting dry type transformers, bushings, current transformers, potential transformers, HV switch insulators, arc-distinguish coils and other electric apparatus.

It is applicable for with-stuffing casting and without-stuffing casting.

It is suitable for degassing, mixing and casting high polymer materials under vacuum condition, such as bisphenol-A, outdoor-type epoxy resin, polyurethane, etc.

It is applicable for processing both mixed material with stuffing added by user and double-component pre-mixed stuffing, very flexible.

The equipment system can be added or reduced according to user’s requirements. It can be modularly rigged. It is characterized by convenient installation, easy operation, and high automation.

Main features

- Perfect vacuum system: the whole process is carried out under vacuum condition.

- Reliable metering system: there are two kind of metering methods based on different process requirement:

l  Feeding pump + electronic scale (for casting with stuffing)

l  Metering pump + static mixer (for casting various kind products)

- Advanced and safe heating technology:

l  Mixing tank is heated by , good temperature uniformity, high precision temperature control

l  Casting tank is heated directly by electric heating plate

- Advanced & reliable metering and control system: controlled by computer, key process and those easy to be mis-operated are controlled interlocked; Process revising, process curve recording, process parameter adjusting, can be achieved by computer very conveniently. The whole metering control and vacuum control are all full pre-set automatic.
