Safety and Insulation transformers

The thermal insulation class indicates the ability of the enamel coating on the copper conductors to withstand the temperature rise generated during transformer operation.

In practical terms, it defines the maximum operating temperature the insulation can tolerate without degrading, thereby ensuring the product’s safety and long-term durability.

All our transformers are built using Class F materials (155°C), providing high thermal resistance and reliable performance even under demanding operating conditions.

There are different types of insulation, but the most common are basic insulation and supplementary insulation.

Basic insulation provides the primary barrier separating live parts from the rest of the system, ensuring protection against accidental contact.

Supplementary insulation is an additional, independent layer designed to act in case the basic insulation fails, thereby enhancing overall safety.

All our transformers feature double insulation between primary and secondary, achieved by increasing the insulating layers, to ensure enhanced safety and long-lasting performance.

A single transformer, more windings, more space at low cost

With the advancement of technologies, the challenges for plant designers increase.

O.c.e. , with its multi-output transformers, aims to help its customers with space problems. With our technology, users with different voltages and powers can be powered in a single product. This perspective shows some benefits:

More space available (one transformer, more customized outputs)

Low purchase costs

In control and command electrical panels, single-phase transformers are used to supply isolated power to low-voltage auxiliary circuits, such as relays, contactors, signal lamps and control devices.
This electrical isolation allows the separation between the power circuit and the control circuit, improving overall safety and reliability of the electrical panel.

Single-phase transformers are commonly installed in industrial and civil systems to supply auxiliary devices that require voltages different from the main power network (including 24 VAC, 110 VAC, 115 VAC and 230 VAC applications), providing the appropriate AC voltage needed for the correct operation of auxiliary and control circuits.

In industrial and civil electrical system revamping projects, single-phase transformers are often retained to supply already-wired low-voltage auxiliary circuits.
In many legacy applications, it is preferable to continue using safety voltages such as 24 VAC, avoiding a full replacement of existing wiring, electrical panels, and installed devices.

Using a single-phase transformer in these contexts allows for:

• Supplying the necessary power to auxiliary circuits without modifying the existing infrastructure

• Ensuring electrical isolation between power circuits and control circuits

• Maintaining compatibility with previously installed devices, such as relays, contactors, and signal towers

Voltage Supply and Adaptation – Marine Auxiliary Circuits

Transformers supply auxiliary circuits such as interior lighting, signal towers, control systems, and other onboard devices.
They also allow conversion of the voltage available from the vessel or shore power to match the requirements of the loads, ensuring compatibility with already installed circuits without invasive modifications to the system.

Electrical Isolation and System Protection

When connecting to external power networks (shore power), transformers provide electrical isolation between the vessel and the dock, reducing the risk of electrical faults, interference, and damage to sensitive equipment.
Transformers can be single-phase or three-phase, depending on the complexity of the system, and are used in both small onboard installations and more complex marine electrical setups.
