PRECOMPRESSED PRESSBOARDS

WIPRESS, a hard and rigid board having high purity with excellent electrical and mechanical properties, is specifically produced for the high voltage and extra high voltage Transformer Industry. The product is made from imported virgin softwood sulphate pulp. WIPRESS is conforming to International and Indian Standard viz. IEC 60641 B.3.1, JIS C 2305, DIN 7733, BS 231-1975 & IS - 1576 - 1992 etc.

Thickness Range : 0.5 mm to 6 mm

LAMINATED PRESSBOARDS

A most modern multiday-light Hydraulic Press of 1200 tonnes capacity of size 2.2 x 1.1 meters with Thermic Fluid Heating is used for the manufacture of Laminated Pressboards.

Precompressed Pressboards are cellulose based and are produced from kraft unbleached softwood pulp having high chemical purity and low conductivity. They are produced on intermittent board machine and compacted without added bonding agents in multi day-light press under heat and pressure to achieve required properties. The boards are characterized by high density, high purity, uniform thickness, dimensional stability, low compressibility, low shrinkage and high electrical strength.

MACHINED COMPONENTS

We supply a varity of custom designed machined components of pressboard for production of output transformers and distribution transformers. Components of pressboard are used in oil-cooled power transformers and distribution transformers primarily due to their high purity, mechanical strength and optimal oil-impregnability. The components formed of pressboard, such as angle rings, snout segments and end leads, enable an exact adaptation to the electric field conditions prevailing in the transformer.

MOULDED COMPONENTS

We supply a varity of custom designed moulded components of pressboard for production of output transformers and distribution transformers. Components of pressboard are used in oil-cooled power transformers and distribution transformers primarily due to their high purity, mechanical strength and optimal oil-impregnability. The components formed of pressboard, such as angle rings, snout segments and end leads, enable an exact adaptation to the electric field conditions prevailing in the transformer.

Pressboard components are increasingly delivered in the form of pre-assembled winding kits. The kits are delivered to the winding machine complete with all necessary components for assembly of a winding. This cost-effective system saves our customer time and labor and solves the problem of limited floor space. More and more OEM‘s are taking advantage of this opportunity by switching from ordering individual components to pre-assembled kits.
