Description

TECHNICAL FIELD

[0001] The present application relates to the field of optical cable monitoring, in particular to an online monitoring device for power optical cable. BACKGROUND

[0002] At present, the power optical cable is usually a cable similar to a rope formed by several or several groups of twisted wires, the wires in each group are insulated from each other, and are usually twisted around a center, and the whole is wrapped with a highly insulated covering layer. The cable has the characteristics of internal power supply and external insulation, and is used to connect circuits, electrical appliances, etc.

[0003] In the existing optical cable use process, long-distance laying is required. Due to the limited production length of the optical cable, several rolls of optical cable are required to connect during the laying process of a long-distance optical cable. The joint is treated at the connection, and the insulation layer is rewound outside the joint for insulation treatment.

[0004] The prior art in the above has the following defects: after the joint treatment of the optical cable joint, the resistance of the joint is generally large, so that the joint is most prone to high temperature during the use of the optical cable. The high temperature of the optical cable joint will cause the insulation layer of the joint to age rapidly. If the optical cable continues to be in a high temperature state, the service life of the optical cable will be reduced. Content of the utility model
