1. Armored cable mechanical protection layer can increase the mechanical strength of the cable to improve the erosion resistance, is vulnerable to mechanical damage and highly vulnerable areas of the design of the telephone cable. Can be laid in any way, more suitable for the rapid installation of rock areas. Armored cables are generally fixed laying power cables.
While unmour cable mainly be laid indoor or other general industrial environment.
2. Cable with the purpose of armor layer also can enhance the tensile strength, compressive strength and other mechanical protection to extend the service life.
Armored with a certain anti-external performance, but also can guard against the mouse bite, so that can protect the cable in power transmission process, armor bending radius to be large, armored layer can be grounded to protect the cable.
3. The cost of armour cable is higher than unarmour cable.
