Product Information

Specification

Also known as:

Single-phase transformers, Submersible electrical transformers, Electrical transformers, Low Voltage Current Transformer.

About:

The tank of these transformers is made of high quality stainless steel sheet and with a special electrostatic paint coating, which allows a surface of great resistance and durability in corrosive environments. Additionally, the equipment has dead-end bushings and special elements for protection and maneuvering, which are located on the tank lid, which facilitates operations using a pole from the surface, even in flood conditions.

Notes: This product can be customized as per customer requests.

Elements Of Protection And Maneuver:

• Removable and interchangeable Bay-O-Net type fuses, which protect equipment against extreme network failures and overloads.
• Built-in limiting fuses that protect the primary network from high current faults in the windings.
• DPS or elbow-type overvoltage arresters, which protects the equipment against over voltages produced in the network.
• Disconnector with opening capacity under load, which allows maneuvering operations.
