Problems solved by technology

[0006] 2. Due to its poor mechanical properties, ordinary communication cables are easy to break in the harsh environment of the mine, which affects the communication function
[0007] 3. Poor environmental protection and safety performance
[0008] 4. Insufficient intelligent interaction, unable to conduct unified monitoring and management of electrical equipment under the mine
Due to the lack of collection and analysis of power consumption information, it is impossible to guide the reasonable power consumption during peak power consumption

Abstract

The invention discloses an optical-fiber composite low-voltage intelligent cable used in coal mine. The optical-fiber composite low-voltage intelligent cable comprises: an insulation core, a fiber unit and a control cable unit. The cable is characterized in that: rubber strip fillers are filled in gaps between the insulation core, the fiber unit and the control cable unit; a taped covering, a fire protection layer and an over sheath are successively arranged out of the insulation core, the fiber unit, the control cable unit and the rubber strip fillers. The optical-fiber composite low-voltageintelligent cable of the invention has good fireproof performance, a mechanical property, an insulating property, a flame retardant property and an acid-resisting / alkali-resisting anticorrosion performance, and possesses low costs and a fiber communication function.

Description

technical field [0001] The invention relates to an optical fiber composite low-voltage intelligent cable and a preparation method thereof, more particularly to a preparation method and its product of an optical fiber composite low-voltage intelligent cable for coal mines, which integrates the functions of optical fiber communication and power transmission. Background technique [0002] On March 5, 2010, Premier Wen’s "Two Sessions" government work report pointed out: make full use of the existing information infrastructure, actively promote the overall planning and co-construction and sharing of triple play networks, and vigorously promote the construction of smart grids. [0003] As one of the important cable products in the construction of smart grid, the optical fiber composite low-voltage smart cable for coal mines integrates the functions of communication and power. Using optical fiber composite low-voltage cable (OPLC) technology to realize power fiber to the terminal,...
