Abstract

The invention provides a distributed optical fiber temperature measuring and communication cable, which comprises one or three cabling wire cores, wherein each of the cabling wire cores comprises a temperature measuring optical cable, a communication optical cable and copper wire conductors, the temperature measuring optical cable, the communication optical cable and the copper wire conductors arestranded to form a stranded conductor, and the temperature measuring optical cable and the communication optical cable are arranged in the copper wire conductors. The distributed optical fiber temperature measuring and communication cable can have functions of temperature measurement monitoring and communication control.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a distributed optical fiber temperature measurement and communication cable. Background technique [0002] As one of the largest supporting industries in the national economy, power cable is the foundation of various industries. Its products are widely used in electric power, construction, shipbuilding, petrochemical and other fields, and are known as the "blood vessels" and "nerves" of the national economy. closely related to national economic development. [0003] The design life of ordinary power cables in my country is more than 20 years, and the design life of medium and high voltage power cables is more than 30 years. The main factors that affect the life of the cable are the following factors: external force damage, insulation damp, chemical corrosion, long-term overload operation, laying environment, etc. [0004] At this stage, the popularity of electric power ...
