The construction of a mineral insulated cable is as follows:
– one or more wire- like conductors (cores) are embedded in a high insulation quality mineral powder and pressed into a metal tube (sheath) made of oxidation and corrosion resistant material. The entire material combination is then processed using suitable forming steps to obtain the final dimensions.

1. Assembly

First We dry the insulation material(MgO). It will improve insulation resistance of mi cable. 

Second We straighten the conductors. 

Third we will clean tube. 

To avoid humidity being absorbed by the hygroscopic insulation material the components are dried thoroughly and filled at an elevated temperature.

2. Drawing and Rolling

Swaging is the optimum forming method for certain types of our mineral insulated cables, naturally special equipment must be emplyed. Ther inner conductors are best protected when processed on a continuous calibre mill. However, the tolerances generally required for the sheath wall limit the use of the method to a few special designs.

3. Annealing

The production of a flawless mineral insulated cable right down to the smallest dimensions requires a considerable number of intermediated annealing processes.

4.Test

5. Mi cable in stock

We have a great stock foer most types mi cable.

Quality Control System

With experienced engineers and QA workers, each manufacturing process is checked and audited strictly. Incoming quality control conducts inspections and handle quality issues before the assembly process starts. Our In-Process Quality Control process governs our quality systems during the assembly process in order to detect and handle any problems that may arise during assembly. Outgoing quality assurance is the last process before products ship to customers, and hence is very important in ensuring our shipment is defect-free. Numerous redundancies with IQC and IPQC exist here to ensure the validity of previous processes.

We have a professional R&D team in the field to provide products with the best quality and high stability. Cooperating with well-known institutions of higher learning and research institutions at home and abroad. A number of the core technological achievements and technical indicators at the international advanced level.

We have professional technician team all in this area more than 10 years, welcome customers from all over the world visit our website, and inform us if you have any needs, we are looking forward to give you good services!
