Little Known Facts About Pre compressed press board.
Pre Compressed Insulation Board: Critical Insulation for Electrical Applications

In the high-voltage sector, insulation is essential for ensuring safe and long-lasting operation. Among the most preferred insulating solutions, the pre compressed press board has become an integral part in transformer design. Its excellent strength, stable dimensions, and compression resistance make it well-adapted for demanding installations that demand both insulation and structural performance.
India has steadily emerged as a manufacturing center for high-grade insulation materials, with companies like Pristine Technologies standing out as a pre compressed press board manufacturer in India offering custom-fit solutions to a broad international client base.
What is Pre Compressed Press Board?
Pre compressed press board is a engineered cellulose insulation material created through advanced mechanical and thermal processes that improve its physical attributes. Made from unbleached cellulose kraft pulp, it undergoes sheet formation, precise drying, and heavy calendering to produce a uniform board with high strength and low moisture retention.
This material is extensively used in reactive devices, offering long-term insulation under high electrical load. Its compatibility with oil ensures that pre compressed press board maintains integrity for extended periods.
Applications of Pre Compressed Press Board
Thanks to its stability, pre compressed press board is a go-to material in multiple power sector components:
• Internal shielding in transformer windings
• Structural parts like U-channels and end rings
• Tubular shielding for windings
• Pressure-bound parts
Its low moisture absorption and tight dimensional tolerance allow clean integration into high-precision electrical setups.
