Insulation joints are used to interrupt the electrical conductivity of the pipe or the cathodic protection system. Integrated lightning protection for high voltage spark gap through patent. This means that the insulating joints are not electrically and surge occurred after the full function.
Lightning protection is attributed to the spark gap of the invention and the patent of the Shu Ke group. Construction to ensure that the electric field is concentrated at the point of this definition and that the spark does not propagate along the surface of the insulating material during the jump. If the spark is to jump on the thermal insulation material, the burning area, the insulation joint will conduct electricity due to the carbon fiber, so the defect. Spark gap rotation to avoid burnout. Therefore, the spark basically runs down.
SHD insulating joint has a variety of versions, the pressure level of various media such as gas, water and heat pipe connection type, is the traditional architecture in different channels, such as for plant construction and compressor and regulating station.
