Protecting the Environment with an Appropriate Containment Solution

Compliance with Dielectric Oil Retention Requirements

MV and HV electrical transformers contain dielectric oils or hydrocarbons whose leakage can cause major soil and water pollution. In accordance with regulations, each unit must be equipped with a containment system (tank, pit, or liner) capable of holding at least 100% of the volume of dielectric liquid present. These systems ensure environmental safety and the regulatory compliance of industrial installations.

Total Containment Capacity for MV and HV Transformers

The full dielectric capacity containment pits designed by SANERGRID® guarantee optimal watertightness and high mechanical strength. Their robust and modular design meets the requirements of distribution transformers, power transformers, and sensitive industrial installations.

A Complete Range for Standard Requirements Not Subject to Fire Risk

BDRG Metallic Containment Basins with Removable or Welded Panels

BDRG metallic containment basins are available in versions with removable or welded side panels, offering high installation flexibility.

They are available in hot-dip galvanized steel, painted steel, or with CH5 GALVAGRID® treatment depending on environmental exposure conditions and technical constraints.

These models provide a durable solution for permanent installations.

 

TRFLEX Flexible Liners for Temporary and Long-Term Containment

Lightweight, cost-effective and easy to deploy, TRFLEX® flexible liners (ECO, ECO+, SUPER-ECO) provide an ideal temporary containment solution for difficult-access sites or maintenance works.

The reinforced version, TRFLEX®-REFOR, equipped with a high-resistance tubular structure, is designed for the most demanding conditions and also enables long-term storage of oil-filled transformers.

Manufactured from waterproof and resistant materials, all liners ensure effective dielectric protection while simplifying logistics.

 

TRT-MODULO Modular Basins for Specific Installations

The TRT-MODULO® system, composed of multiple assembled sections, allows adaptation of containment systems to the most complex configurations.

Its modular design adjusts to transformer dimensions and geometry, ensuring a tailor-made installation even on sites with space or accessibility constraints.

 

Standard or Custom References According to Your Equipment

Distribution Transformers from 160 to 3150 kVA

SANERGRID® containment basins are available in standard references for MV distribution transformers ranging from 160 to 3150 kVA.

These models cover most electrical distribution needs and guarantee a high level of safety and performance.

 

Autotransformers, Reactors and Oil-Immersed Power Transformers

Specific designs are also available for autotransformers, shunt reactors (IC) and HV oil-immersed power transformers (such as KOLEKTOR ETRA types).

SANERGRID designs custom containment basins adapted to the technical characteristics and operational constraints of each installation.

 

Containment Basins Designed for Long-Term Durability

Galvanized, Painted or GALVAGRID® Treated Steel

The materials used ensure excellent resistance to corrosion, weather exposure and transformer mineral oils.

The choice of coating (galvanization, industrial paint or CH5 GALVAGRID® treatment) depends on environmental conditions and guarantees optimal long-term durability.

 

Resistance to Outdoor Environments and Hydrocarbons

Designed for both indoor and outdoor use, SANERGRID® basins maintain their mechanical properties even when exposed to UV radiation, temperature variations or hydrocarbons.

They provide maximum safety throughout the entire transformer lifecycle.

 

The Most Comprehensive Range on the Market, Designed for Field Constraints

Indoor or Outdoor Installation with Rainwater Filtration

SANERGRID® solutions can be installed indoors or outdoors and combined with SPI filters for safe drainage of rainwater contaminated with hydrocarbons.

These systems enable secure gravity flow drainage and prevent overflow risks.

 

Load Capacity Adapted and Transformer Rolling Inside the Basin

Each basin is dimensioned to support transformer weight, including during movement.

Reinforced structures allow safe rolling of the transformer inside the basin, facilitating maintenance operations and ensuring optimal on-site integration.

 

Unique Accessories and Options to Customize Your Installation

SANERVIB Anti-Vibration Mounts, PTFE Plates, SANERBLOCK® Locking Clamps

To enhance stability and safety, basins can be equipped with specific accessories:

SANERVIB® anti-vibration mounts

PTFE (Teflon®) plates for electrical insulation

SANERBLOCK® clamps for locking transformer wheels

 

SPI® Filters, Fire Covers and Complementary Safety Elements

SANERGRID® also provides SPI® filters for rainwater filtration, fire-resistant covers and various protection devices to ensure a complete installation compliant with environmental and safety requirements.
