3.Difference bttyz and BTTZ cable

BTTZ cable includes bttyz cable and BTTVZ cable, namely the relation between parent and subclass. Generally, BTTZ cable is not equipped with outer sheath, which can be directly laid or buried. However, if the laying environment, such as acidic soil, needs to be equipped with anti-corrosion coat, the outer sheath should be selected to protect. In addition, the terminal connector and intermediate connector of bttyz cable are the same as those of BTTZ cable, and the installation and laying are the same. So the difference between bttyz and BTTZ cable is one more layer of outer sheath.
