During the use of Cable Protector, there will be some factors that cause its malfunction. These factors are either internal or external. Everyone should understand and correct them after identifying the fault. The causes of Cable Protector malfunction are as follows.
Due to the breakdown and destruction of the outer sheath of the cable due to the overvoltage of the metal sheath, the ultra-high voltage cable is often forced to reduce the transmission capacity. In order to reduce the overvoltage of the sheath to the ground and avoid the breakdown of the outer sheath, a sheath protector is widely used as a voltage limiting device to ensure the reliable operation of the cable. Cable Protector has experienced the evolution history of spark gap, silicon carbide valve plate protection cover, and metal oxide protection cover.
The Cable Protector sleeve is the outermost layer of the cable, as the most important barrier to protect the internal structure of the cable, and protects the cable from mechanical damage during and after installation.Cable Protector sleeves are not intended to replace the reinforced armor inside the cable, but they can provide a fairly high level but limited means of protection. In addition, the cable jacket also provides protection from moisture, chemicals, ultraviolet rays and ozone. So, what are the materials for the Cable Protector sleeve?
