Densified Wood Laminate
InsuLam® is a specialty wood composite product that combines the dielectric properties and stability of thermosetting resins with the strength and toughness of wood fibers. The result is essentially a wood reinforced plastic material whose mechanical properties can be engineered to meet the needs in a variety of applications.
InsuLam® is manufactured in two specific grades Insulam LH™ and Insulam EH™
Insulam EH™ Fully Impregnated densified Laminated Wood
Insulam EH™ is a fully impregnated densified wood product that offers high mechanical strength, high dielectric strength and dimensional stability. It is usually significantly less expensive than NEMA-grade glass laminates – and stiffer than other phenolic laminates. The veneer grain of Insulam EH™ can be arranged to put the greatest strength where it is needed. The product is easily machined and can be used in cryogenic applications. Insulam components are widely used in Electric Power equipment.
lnsulam EH has been proven in service by liquid natural gas (LNG) transportation and storage vessels. Successful land and sea applica-tions include tank sealing rings, pipe saddles, tank supports, keys and pitch-and-roll chocks.
Insulam LH™ Non Impregnated Densified Laminated wood. (IEC 61061)
Insulam LH™ is non-impregnated product which is manufactured to comply with DIN 7707, and IEC 61061. This is used primarily for structural electrical components in oil- insulated power transformers. The Major uses of Insulam LH™ are in pressure rings and blocking for power transformers.
Rings are manufactured in 2 densities LH77P72(IEC TYPE T4R), and LH77P60(IEC type T2R)
InsuLam® offers high mechanical, thermal and dielectric strength as well as dimensional stability. The veneer grain can be arranged and pressed to put the greatest strength where it is needed. The density and impregnation levels can also be varied to match the desired properties for the application. The product is easily machined with good dimensional tolerances, and it is compatible with most paint, varnish and transformer oil.

The process begins with select thin red beech veneers from Europe where the wood is of the finest and most consistent quality. Depending on the desired properties, the veneers are either impregnated or surface coated with a specially formulated electrical grade phenolic resin. Following resin treatment, the veneers are dried or “B-staged” then arranged and stacked into the defined configuration and thickness. Lamination, densification, and curing are accomplished simultaneously in massive presses under high pressure and heat. After the pressing cycle, the material may be precision machined, assembled and finished per the requirements of the application.
