Tube & Rods For Insulation

Millborn Switchgears offers world-class SRBP (synthetic resin bonded paper) and SRBF (synthetic resin bonded fabric) tube and rods. SRBP tubes are produced by winding a pre-impregnated phenolic paper (electrical grade) through heated roller on high pressure rolling machine. It has excellent di-electrical strength in both air and immersed in oil and good mechanical properties, low water absorption and high insulation resistance. It is produced in various shapes like round, square, rectangular, hexagonal, etc., in inner dia 2 mm to 630 mm and length up to 1600 mm. Applications are in distribution transformers, expulsion fuses, switchgears, bobbins and for other electrical insulation purpose. The process for SRBF tubes and rods is similar: manufactured with fine/medium weave cotton fabric which is bonded with phenolic resin, developed to complement the range of moulded tubes and rods. Having good mechanical strength and low water absorption, it is resistant to weathering and chemical attack by mild acids and alkalis. These are most commonly used to manufacture mechanical and wear resistance components for a wide range of engineering applications like bushes, seals, etc. They are strong and rigid, with good bursting strength and excellent wear resistance in lubricated applications.
