The 500mm construction hydraulic butt fusion machine selects electrodes with different outer diameters, and selects a smaller diameter on the side of thin parts or workpieces with good electrical and thermal conductivity to increase the current density on this side and reduce the influence of heat dissipation of the electrodes; For different electrode materials, copper alloys with poor thermal conductivity are selected on the side of thin parts or workpieces with good electrical and thermal conductivity to reduce heat loss on this side; A gasket made of metal with poor thermal conductivity is placed on one side of the good workpiece to reduce heat dissipation on this side.

　　To prevent electric shock of 500mm construction hydraulic butt fusion machine:

　　1. The casing of the 500mm construction hydraulic butt fusion machine must be grounded. The purpose of grounding is to prevent the 500mm construction hydraulic butt fusion machine from accidentally hitting the shell and injuring people, and it is indispensable in any situation. The grounding body of the 500mm construction hydraulic butt fusion machine can widely use the natural grounding electrode, such as the water pipeline, the metal structure of the building that has a reliable connection with the earth, etc. However, it is strictly forbidden to use the pipeline of inflammable and explosive materials as the natural grounding body. If the resistance of the natural grounding electrode exceeds 4Ω, use an artificial grounding body, otherwise, it is likely to cause an electric shock accident or even a fire.

　　2. The insulation of the welding tongs of the 500mm construction hydraulic butt fusion machine must be reliable, and it is strictly forbidden to use electric welding tongs without a casing to prevent accidents.

　　3. The staff must wear gloves when changing the welding rod. If the clothes are soaked with sweat, they are not allowed to lean on metal objects to prevent electric shock.

　　4. The construction personnel must disconnect the power switch when repairing the 500mm construction hydraulic butt fusion machine, and the switch must have an obvious disconnection gap, and then use an electric pen to check to ensure that the power has been cut off before starting maintenance.

　　5. When the 500mm construction hydraulic butt fusion machine is moving, the power must be cut off, and it is not allowed to move the 500mm construction hydraulic butt fusion machine by pulling the cable.

　　6. If the 500mm construction hydraulic butt fusion machine has a sudden power failure during work, the power supply should be cut off immediately to prevent electric shock from suddenly coming.
