2. Whether the installation of all wiring accessories is intact and whether the waterproof seal is damaged;
3. Whether the pipe fittings have been repaired and caused damage to the electric heat tracing;
4. Whether the insulation layer is damaged or crushed;
5. Isolate each section of the electric heat trace of the line and test the fault with a shake meter;
► Reason (4)
1. Mistakenly connect the two wires of the electric heat trace at the end end;
2. The insulation layer of the first and last section of the electric heat trace is thermally contracted, and the conductor is short-circuited with the pipeline or shield;
