  • Temperature indicating (wax) sheet

    Properties and application

    SW series temperature indicator is widely used in the bus connection of substation to monitor whether the bus contact is good or not. It is an indispensable protection to ensure the safe operation of substation.

    In order to ensure the safe operation of substation busbar, it is necessary to know the temperature rising situation. The temperature indicator can be used to supplement the deficiency of general thermometer. In the inspection, it is found that the temperature ...MORE

  • Conductive Paste

    Properties and application

    Conductive paste is widely used in the contact surface of the bus-bars, bus-bars and equipment terminals, and disconnecting switch contacts which located in power substations. The conductive paste can be used to connect between two same or different metal conductors (such as copper and copper, copper and aluminum, aluminum and aluminum). The uses of conductive paste can greatly reduce the contact resistance (reduced by 35-95%) so as to reduce the temperature (reduced by 35-85%), for this reason, the conductive paste is an excellent replacement for tinning...MORE
