Distribution transformer for explosive atmosphere
12 kV, max. 3 500 kVA Brush

The BRUSH range of dry type flameproof transformers are available with ratings up to 3500kVA, 12kV, and use class '220' insulation as standard, which possess superior thermal stability, are highly resistant to moisture and are impervious to deterioration by ageing.

The range of flameproof enclosures used have been type tested and certified by a notified body and are suitable for use in Group I atmospheres containing methane (firedamp), such as encountered in the mining industries. In addition a number of enclosures are suitable for use in Group IIA and IIB atmospheres containing Propane and Ethylene, such as encountered in the surface industries (e.g. petrochemicals).

Although originally designed for use in the underground coal mining industry, these flameproof and robust transformers are recommended for use in hazardous atmospheres such as carboniferous mining, the oil and gas industry and the chemical industry. Because of their very robust construction they are suitable for use in non-carboniferous and open cast mining, quarrying, tunnelling and heavy industry - where their robust construction is valued more than their flameproof characteristics.
