The outer protective layer is the protective covering layer wrapped outside the cable sheath (inner protective layer), which mainly plays the role of mechanical strengthening and anti-corrosion
. 
There are two kinds of cables in common use: the outer sheath whose inner sheath is metal sheath and the outer sheath whose inner sheath is plastic sheath
.
The outer protective layer of metal sheath is generally composed of backing layer, armor layer and outer coating layer
.
The liner layer is located between the metal sheath and the armor layer, which plays the role of anti-corrosion of the liner and metal sheath
.
The armor layer is metal belt or wire, which is mainly used for mechanical protection, and the wire can bear tensile force
.
The outer coating layer is outside the armor layer, which has anti-corrosion effect on the metal armor
.
The village cushion and outer cover are composed of asphalt, polyvinyl chloride tape, impregnated paper, polyvinyl chloride or polyethylene sheath, etc
.
According to the different environment and conditions of various cables, the composition and structure of the outer sheath are also different
.
The outer sheath structure of various types of power cables is shown in the table of various cable types
