Product catalog summary

Introduction
We are pleased to announce the development of a new Integrated Voltage Transformer (IVT) in collaboration with ENEL, Italy. This IVT is designed for use with the motor of the MV three-phase Outdoor SF6 Insulated Pole Mounted Load Break Switch.

Product Specifications
The IVT features a phase-to-phase voltage transformer connected to the MV line via plug-in bushings (type A interface) and protected by two MV fuses. It is housed in a metal case with a protection rating of ≥ IP 55, made of stainless steel, and includes hooks for pole mounting. The connection to the motor is facilitated by a plug with a protection rating of ≥ IP 55.
