  • ED-2B Low Voltage Porcelain/Ceramic Shackle Insulator

    ED-2B Low Voltage Porcelain/Ceramic Shackle Insulator

    Low voltage line insulators are used for insulation and fixing of power line conductors with power frequency AC or DC voltage below 1KV. There are mainly needle type, screw type, spool type, tension and tram line insulator, etc. Butterfly and spool insulators can also be used for insulation and fixation of conductors on low-voltage line terminals, tension and corner rods. Tension insulator is used for insulation and connection of pole stay wire or tension conductor.
    Insulators are widely used devices, and their connecting fittings are also required to be interchangeable. In addition, the technical standards of butterfly insulators also require various electrical, mechanical, physical and environmental condition change tests on insulators according to different models and service conditions, as well as environmental condition change tests, so as to test their performance and quality.

  • Fuse Cut-out Bushing Insulator

    Fuse Cut-out Bushing Insulator

    A bushing must be designed to withstand the electrical field strength produced in the insulation, when any earthed material is present. As the strength of the electrical field increases, leakage paths may develop within the insulation. If the energy of the leakage path overcomes the dielectric strength of the insulation, it may puncture the insulation and allow the electrical energy to conduct to the nearest earthed material causing burning and arcing.

    36kv 30NF250 High Voltage Transformer Porcelain Bushing

    The transformer bushing is the main insulation device outside the transformer box. The lead wires of the transformer windings must pass through the insulating bushing to insulate between the lead wires and between the lead wires and the transformer shell, and at the same time play the role of fixing the lead wires. Due to the different voltage levels, insulating bushings include pure porcelain bushings, oil-filled bushings and capacitor bushings.
