How To Install Mineral Insulated Cable?

1. Cut a trace line in the cable with a pipe cutter according to the required length.
2. Use a pair of diagonal pliers to twist the sheathed copper skin clockwise between the jaws, clamp the edge of the sheathed copper skin step by step, and rotate and peel the clad copper skin at a small angle until the cutting mark is reached.

3. Thoroughly remove the magnesium oxide insulation from the bare wire with a clean, dry cloth, then place the harness head on the cable and screw the brass sealing cup vertically on the copper sheath of the cable sheath. First, check the sealing cup’s verticality by twisting it by hand and sliding the bundle head over the sealing cap. Once truly vertical, clamp the sealing cup’s knurled seat with a pipe wire clamp and continue the installation until the end of the tiger skin is below the partial thread inside the sealing cup!

4. At approximately the distance, starting from the cable trip, heat the cable 600 mm using a torch flame and continuously move the flame to the cable’s open end to remove moisture. Remember to move the flame to the open end of the cable only. Otherwise, moisture will enter the cable.

5. Use an ohmmeter to measure the insulation resistance between the core and the sheath. If the measurement result meets the requirement, the sealing paste can be injected into the sealing cup.
6. Note that sealing paste should be added gradually from one side, not too fast, to expel air. When the sealing paste is completely filled, press the cup cover and then cover the wire core with a heat-shrinkable sleeve.
