Description
Technical Field
The invention relates to the technical field of cable sheaths, in particular to an optical cable sheath and a preparation method thereof.
Background
The electric wire and cable are carriers for power transmission and information transmission, and are widely used in industrial and civil electric facilities. The requirements of the electric wire and the cable are different when the electric wire and the cable are used in different environments or occasions, which puts higher requirements on a cable sheath coated outside the electric wire and the cable. The main function of the cable sheath is to protect the transmission cable wires mechanically and electrically from the various conditions that would cause them to lose their transmission function. The cable jacket must perform this protective function during installation, splicing and throughout the service life of the cable. The sheath must protect the cable core from moisture and other contaminants over the service life of the cable to the extent that the loop performance in the cable core remains normal, and the transmission performance deteriorates significantly once excessive moisture or other contaminants enter the cable core. This requires the cable sheath to have high mechanical strength and internal toughness to prevent cracking or breakage in a harsh environment, which may cause malfunction of cable transmission or safety hazard.
