Monobloc or modular large volume retention tank, compliance with environmental standards under station and long term storage

The SONEC BGS range of galvanized bunds covers all the regulatory and technical aspects related to the long-term storage of transformer oils, hydrocarbons, esters or other materials. Mainly used in the field of electric oil transformers, the BGS bund is also intended for users of equipment containing all types of non-explosive hydrocarbons.

This range is composed of a series of monobloc or modular bunds that can be adapted to the required retention volume.

Monobloc bunds: Often used for small transformers less than 2200 mm wide, they are made of hot-dip galvanized steel and guarantee a similar internal and external life span to that of the electrical transformer or other machine they equip. The BGS range is not designed for use with live transformers: for this, please refer to the BCF range, made of metal but equipped with CCF fireproof covers

Modular trays: Used for larger transformers or power transformers, when the width of the transformer exceeds 2200 mm and the tray does not fit into a standard transport jig. These trays can be connected to each other.

These bunds are made of hot-dip galvanized steel, which guarantees a similar internal and external life span as the electric transformer or other machine they are fitted with. Unlike SONEC’s flexible BS bunds, the BGS is not very sensitive to UV rays and wind, and its anti-corrosion protection is superior. Moreover, if requested at the beginning, the BGS can be converted into a BCF by adding the CCFor LHDfirewall system.
