Cartridge heating element is made of a metal tube as a shell, which is loaded with alloy resistance wire as heating element, filling and compaction around the alloy wire with good insulation and thermal conductivity of oxidation powder, in the end of the tube out of the terminal post or lead.
Why does an electrically heated lead break? It is that using outside wiring.
There are several solutions:
1. The use of internal lead
2.Using metal hose as sheath
3.Adopt metal braided protective sleeve
4.Using Magnetic bead leads
