Underground distribution solutions for electric utilities

ISG-SD solid-dielectric switchgear

Available for padmount, vaultmount/wallmount and submersible installations, ISG-SD solid-dielectric switchgear provides a reliable, efficient and sustainable solution for underground power distribution.

• Reliable: ISG-SD switchgear is manufactured with stainless-steel tanks and enclosures for maximum durability and reliability
• Retrofittable: Designed to fit within existing padmount and vault footprints, ISG-SD switchgear allows for fast and economical upgrades
• Sustainable: Eaton’s ISG-SD solid-dielectric switchgear includes no oil and no SF6 gas, which means less maintenance and less environmental impact

Vacuum Fault Interrupter (VFI) padmount transformers

Eaton’s Cooper Power series single-phase and three-phase VFI transformers perform double duty in a single, compact and cost-effective package. Combining a conventional pad-mounted transformer with the proven VFI, units provide both voltage transformation and transformer/loop overcurrent protection in a design that simplifies installation, reduces costs and requires less real estate.

• Safer: Resettable fault protection eliminates the need for fuses, reducing outage time and providing better performance
• Efficient: Reduces installation, operation and maintenance costs compared to transformer plus separate switchgear
• Compact: Occupies as little as half the space of a conventional set-up while simplifying installation

Padmount voltage regulators and controls

Eaton's Cooper Power series pad-mounted voltage regulators provide state-of-the-art voltage regulation while reducing installation costs and preserving site aesthetics. The pad-mounted voltage regulator, in conjunction with pad-mounted transformers and switchgear, can be used to create low-profile modular substations. These low-profile substations will be unobtrusive and can usually be installed without fencing and possibly in shared rights-of-way locations. Pad-mounted voltage regulator offerings include single-phase, 2-in-1 and 3-in-1 versions.

• Versatile: Voltage regulation of 32 steps (approximately 5/8% per steps) for a maximum of ± 10% in wye-connected banks
• Compact: Low-profile voltage regulation for underground distribution applications
• Secure: Full metal cabinet meeting stringent tamper-resistance standards

Underground cable accessories and tools

Eaton's Cooper Power series insulated connector product line provides maximum flexibility and functionality for underground high-voltage distribution systems. The connector system provides full insulated and grounded devices for splicing and connecting underground cables to equipment and establishing multiple junction points. These products provide a high level of safety and allows for easy disconnecting and grounding of cables for equipment maintenance or change out.
