Why NBR Gaskets Are Ideal for Transformer Sealing

Image
  Introduction Sealing in oil-filled transformers is critical to prevent oil leaks, moisture ingress, and insulation damage. Choosing the right gasket ensures safety, performance, and long service life. What Is NBR (Nitrile Rubber) NBR (nitrile-butadiene rubber) is a synthetic elastomer known for its oil, grease, and fuel resistance, good mechanical strength, and flexibility. Its acrylonitrile content affects oil resistance and low-temperature performance. Key Advantages Oil & Fuel Resistance:  Prevents swelling and leaks. Mechanical Strength:  Tensile, tear, and abrasion resistant. Temperature Range:  Performs well from -40°C to +100°C (air) and up to ~120°C in oil. Cost-Effective:  High performance at lower cost. Compression & Seal Integrity:  Maintains a tight seal under load. Limitations Not suitable for prolonged high temperatures (>120°C). Can become brittle below -40°C. Sensitive to strong chemicals, ozone, and UV exposure. Tips for Select...

Transformer Insulation for Oil cooled Transformers

Image
Oil cooled transformers form the basis and backbone of any transmission and distribution system of power in a country. Oil cooled transformers are the most preferred choice due to their relatively better efficiency and life compared to other types of transformers. Transformer insulation  used in such oil-cooled equipment is cellulosic material made from pure unbleached kraft wood pulp. These can be in different forms namely, Transformer Insulating Pressboard and Insulation paper. Given below are different types of Transformer Insulation which are being generally used: Pre-Compressed Press Board components Pre-Compressed Press Board components  like spacers, ducts, trapezoidal strips, T- strips, blocks, washers or circles, yoke insulation, phase barrier insulation, cylinders, ladders, etc. These are manufactured by machining of transformers insulating pre-compressed pressboards by process of shearing, punching, moulding, rolling, etc. These components are used in ...
