Transformer breather Hawke

HB Type Transformer Breathers

The HB Desiccant Breather is ideal for a large range of Transformer sizes. The charge is constructed from high strength poly carbonate with the additional protection of a polythene coated metal screen, it's identical die cast end plates are sealed in position to form a very strong unit.

HBP Type Transformer Breathers

The HBP Desiccant Breather has been specially designed to provide an economical protection device for smaller Transformers having a low oil content. The Breather body and oil seal cup are moulded in high strength polycarbonate, which offers mechanical strength and weather resistance, the transparent material also allows all round visability of the Desiccant at a distance.
The design of the HBP Desiccant Breather allows the capacity to be increased for use on larger Transformers. This is known as the HBP/2.

Multiple Breather Units Types: HB55, HB66, HB77 & HB777

The design of the Hawke Desiccant Breather in its single unit form (i.e. HB2) has been limited to weights and dimensions which enable easy handling during initial installation and subsequent charge replacement. However, parallel arrangements are available for those situations where the oil volume of the transformer requires larger volumes of Desiccant gel.
Where Breather charges are operated in parallel, it is essential that only one oil valve is used, this maintains a balanced air flow through each branch of the multiple arrangement. The pipe work for the connection of two and three breathers in parallel are standard fittings.
