Enhanced Fire Safety with SANERGRID® Technology

Prevention of Hydrocarbon Pool Fires Under Transformers

Designed to replace traditional gravel or pebble beds, SANERGRID® fire-resistant containment basins provide passive fire protection for MV and HV oil-filled transformers.

Their innovative design acts effectively from the very first minutes on the phenomenon known as a “hydrocarbon pool fire,” while ensuring full regulatory and environmental compliance.

Operation of ERT® and TRT®-LHD Fire Suppression Basins

ERT® and TRT®-LHD basins operate on the same passive safety principle: SANERGRID containment systems are equipped with fire-resistant covers. In the event of burning oil discharge, hydrocarbons are directed beneath fire-resistant shutters or gratings, where oxygen is deprived and combustion is almost instantly extinguished.

This simple, robust and autonomous technology requires no electrical power supply and no mechanical maintenance. Regular cleaning is sufficient to ensure proper operation of the fire-resistant covers.

Regulatory Compliance and Certifications

NFC 13-200, IEEE, IEC Standards

SANERGRID® fire-rated containment basins comply with the most stringent international standards, including NFC 13-200, IEEE, CIGRE and IEC, guaranteeing optimal passive fire safety for all oil-filled electrical installations.

CNPP, SP Boras, Leipzig Testing

Their effectiveness has been validated through independent testing conducted in several European laboratories:

CNPP (2009 and 2011)

SP Boras (2015)

Leipzig (2004)

These tests confirm the proven performance of SANERGRID® technology under real fire conditions and various dielectric oil fire scenarios.

Standard or Custom Models

Adaptation to Center Distances, Weight and Oil Volume

ERT® and TRT®-LHD basins are available in standard versions or configurable custom designs to meet all installation constraints.

Fixed center distance versions (ERT-F® / TRT®-LHD-F) or adjustable configurations allow precise adaptation according to transformer size and weight.

Compatible with MV, HV, AT, TSA, IC Equipment

Our containment basins are compatible with standard equipment including:

MV distribution transformers

HV power transformers

Autotransformers (AT)

Shunt reactors / compensation reactors (IC)

Auxiliary substation transformers (TSA)

SANERGRID® Custom Engineering: Large-Capacity Modular Solutions

For larger transformer dimensions, weights and oil volumes, the modular design of SANERGRID® fire-rated containment basins ensures compatibility with a wide range of equipment by assembling multiple modules into a single integrated solution known as ERT-MODULO® or TRT-MODULO®.

MODULO® Versions for Heavy Transformers and Large Oil Volumes

ERT-MODULO® and TRT-LHD MODULO® models are specifically designed for very high-power transformers weighing several hundred tons and containing tens of thousands of liters of dielectric oil.

Their segmented modular design facilitates transport and on-site installation, even in constrained environments.

Containment up to Tens of Thousands of Liters

These modular basins ensure full dielectric retention and optimal control of pollution and fire risks, regardless of substation configuration.
