ASG are converters and suppliers of pads, made using a multitude of materials, sourced from a range of high quality suppliers and material manufacturers, some of which are needed for specialist applications. One such range of products on offer from our vast catalogue are various types of electrical insulating materials with one type being Synthetic Resin Bonded Paper Electrical Insulation, sometimes also called SRBP Paper, SRBP Board or Phenolic Paper Laminate.

SRBP is usually manufactured in sheet form usually at 1220mm x 1220mm and in a range of thicknesses from 0.5mm to 20mm from which pads can be cut. SRBP pads are produced on-site using drawings or measurements provided by our customers, to ensure the final product is to their exact specification. Depending upon the size and quantity of pads required, one of many presses, bandsaws or CNC machines can be used to manufacture the final product, from one off samples to multiple batch runs

    What Are SRBP Electrical Insulation Pads?

    SRBP is a brown coloured composite material made of stacked layers of paper which is impregnated with a plasticized phenol-formaldehyde resin and bonded under pressure and high temperature, designed for it’s electrical insulation properties, manufactured in sheet form which can be cut and converted into finished products such as pads.

    SRBP pads are cut from stock sheets and often used in the same way as a gasket, whereby they are used to create a seal between uneven surfaces, fill irregularities or provide insulation. Our pads can be produced as squares or rectangles with the option of radius corners, and also as circular or oval shaped pads or ‘discs’, in a range of thicknesses from to 20mm.

    Why Use SRBP Electrical Insulation Pads?

    SRBP pads offer superior electrical insulation properties, making them better suited to medium or high voltage applications in comparison to those made from SRBF, even in applications where there is exposure to humidity and oil in comparison. Because of the rigidity of SRBP, we can convert the sheets using the same processes used for plastics such as routing, drilling, milling and sawing, in order to produce parts such as gaskets or SRBP pads in a range of sizes.

    The Benefits of Using SRBP Electrical Insulation

    • Excellent electrical properties even when submerged in oil.
    • Easy to machine
    • Low moisture absorption even in humid conditions
    • Operating Temperature of 105°C continuous (+120°C intermittent)
    • High thermal resistance.

    Grades Of SRBP Electrical Insulation

    Low Voltage:

    • Meets BS EN60893, standard 3-4 PFCP201
    • Temperature: Up to +100°C continuous
    • More economical grade
    • Used in Low voltage applications

    Medium Voltage:

    • Meets BS EN60893, standard 3-4 PFCP203
    • Temperature: Up to +105°C continuous
    • Better oil absorption than the high voltage grade
    • Low water absorption
    • Used in Medium voltage applications

    High Voltage:

    • Meets BS EN 60893 Standard: 3-4-PFCP206
    • Temperature: Up to +105°C continuous
    • Good electrical properties both in air and oil.
    • Low moisture absorption.
    • High thermal resistance
    • Used in High voltage application

    Advantages Of Using SRBP Electrical Insulation Pads

    Using SRBP pads offer a number of advantages, it is manufactured in a wide range of thicknesses and is available in 3 grades for use with varying levels of electrical voltage.

    As well as the excellent electrical insulation properties, SRBP pads offers a good mechanical strength, low moisture absorption and is easy to cut and form into complex shapes using a range of techniques including routing, drilling, milling and sawing to create pads which can be found utilised in electrical components, electrical switchgear, lighting, transformers and within many engineering applications.
