Medium-Voltage Switchgear


IATS

General Characteristics
  • Highly Reliable
  • High electrical and mechanical life-tested for 2500 switching operations at rated load
  • Maintenance free (A leakage rate of < 0,02%/year, guaranteeing 30 years of service)
  • Ideal for the most adverse environments
  • Environment friendly (low SF6 pressure)
  • Several flexible solutions available

The system combines the following equipment:
  • A three-phase operated mechanism (motor) integrated in the switch body
  • A manually operated mechanism with interlocks
  • Bushing current transformers
  • A remote electronic controller cabinet, controlling a controller/RTU, batteries, battery charger and optional radio (or other) communications system

Advantages
  • Compatible with all SCADA/DA schemes
  • Simple and safe interlocks
  • Maintenance free-sealed for life SF6 tank

Installation
  • Compact and light-weight
  • Easy to install-one piece factory assembled
  • Ideal for adverse environments-sealed tank & non-ceramic bushings
