10 Spares for Substation
Resin cast current transformers are available for metering and protection application. These current transformers are mainly fabricated according to client’s specification. Ct coils are encapsulated in cast resin (polyester / epoxy). Secondary terminals are provided with either screws or studs. The main insulation between primary and secondary and earth is obtained by this epoxy resin. These transformers are of compact design with high mechanical and electrical properties. These are non-hygroscopic and hence give very good insulation properties even in given humid conditions.

We manufacture highly efficient and accurate resin cast potential transformers. These resin cast potential transformers are used in ac circuits, for the purpose of measuring large voltages. Their main function is to reduce the supply voltage to a small value so that it can be easily measured with standard low range ac instruments of moderate size and capacity. There are many advantages of using resin cast potential transformers for range extension of ac meters. We also offer resin cast potential transformers of dual purpose metering & protection that are also commonly used.
As a leading manufacturer and supplier in this domain, we are offering a high quality compact substation which has compact and sturdy design to save space. It is pre-fabricated secondary sub station containing, distribution transformer, medium voltage switch gear, low voltage switch board, connections and associated equipments in a compact unit. All components are housed an enclosure, which protects the equipment from environment hazards and unauthorised access. The electrical equipment is cooled by natural ventilation through openings in the sub station. It is designed in accordance with IEC-61330 standards. The Compact Substation is computerised with suitable medium voltage, low voltage sections and transformer section with separate doors for each compartment.
Industrial metering cubicles are used for the controlling of the incoming power supply voltage and its distribution among the other appliances in the industry in most appropriate and desirable manner. These are provided with auto sensing and intelligence technologies to make its work more efficient and reliable. The cubical are dust proof and pilfer resistant. The cubical are available in three phase three wire or three phase four wire systems. It is widely acclaimed in the industry, owing to its ease of operation, minimal maintenance and low cost.
Features:
Used for indoor/outdoor installations and completely sealable in order to prevent power theft.
Mainly used for amr systems.
Dry type resin cast cts and pts are used.
This being a compact unit is easy to handle.
Less in weight in weight and volume as compared to 5/6 single phase units.
