When a depositor is inquiring about a single head heating tube, we usually ask whether the depositor needs an internal lead or an external lead, because the lead structure is not the same as the lifespan and profit of the heating tube. At that time, depositors would ask whether the single head heating tube is well constructed with an inner lead or an outer report? Yesterday we came to talk carefully. The difference between inner lead and outer report
1. The form of the entry is not the same
The inner lead is an indirect lead from the inside of a single head heating tube, while the outer lead is led from the heating tube by the connecting column and then connected to the lead.
2. The functions are not the same
When the inner lead is under internal bending pressure, it will not break, while the external lead is relatively simple to break.
3. The manufacturing process is not the same
The inner lead wire is normally made of export materials, with a nominal load higher than that of the external reporting single head heating tube. The manufacturing process is also different from the international heating control manufacturing method. External reporting is usually done using external heating tubes.
4. Profit is not the same
The manufacturing profit of single head heating tubes with inner leads is higher than that of externally reported ones. From the following points, it can be seen that the single head heating tube has a relatively good internal lead structure, but the profit is relatively high. The deformity can satisfy the user's request without special use of an external electric heating tube.
