Cable has a layer of external protection, I believe that this should be very well understood, for this layer of external protection, it has quality requirements, what are the quality requirements? Let me give you a brief introduction.

 

Quality requirements of cable external protective coating:

 

1, ac single-phase circuit power cable, it needs to be treated by female metal tape or steel wire to armor.

 

2. For cables used in harsh environment, its external protective layer needs to be specially treated by metal sleeve, reinforcement layer, armor layer, etc., so as not to easily cause damage in harsh conditions, which is also the foundation of its long-term stable use.

 

3, in the low temperature environment or in the use of medicinal chemical liquid immersion, when the cable needs to have the requirements of low toxic refractory cable extrusion jacket, so as to ensure its use.

 

Under different circumstances, there are obvious differences in the requirements for the external protection layer of cables. In practical use, we need to correctly analyze the differences and dialectically use them, so as to fundamentally escort their use.
