Abstract

The invention provides a high-efficiency energy-saving environmental-protection fireproof flexible soft cable used for an intelligent electric network, relates to the field of the manufacture of cables and comprises an insulated cable core, wherein the insulated cable core comprises a power cable core, a control cable core and a signal shielding cable core. A high-flame-retardant glass fibre belt wrapping layer, a copper belt wrapping and shielding layer, a double-layer copper wire weaving and shielding layer, a shielding and wrapping layer and a ceramic fireproof silicon rubber sheath layer are sequentially arranged outside the insulated cable core from inside to outside, a filling material is arranged in a clearance between the insulated cable core and the high-flame-retardant glass fibre belt wrapping layer, and a heterogenic halogen-free filling framework is arranged between a power cable and a control cable; and by the arrangement, the cable can have the capability of resisting strong electromagnetic interference and strong static interference and also has stronger capabilities of high-temperature resistance and fire prevention.

Description

Technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to the technical field of manufacturing cables for smart grids. Background technique [0002] In May 2009, the State Grid Corporation of China announced a three-step development outline for my country's "strong and smart grid", which has aroused strong support from several major power groups. As of the end of 2009, my country has carried out pilot and demonstration projects in many aspects of the smart grid, including large-scale grid operation and safety, smart dispatch, digital substation, distribution automation, user information management, renewable energy grid integration, and electric Key pilot projects such as car charging and discharging stations. [0003] According to data, the State Grid’s investment in power grids in 2010 will be around 270 billion yuan, and the total investment in smart grid construction in the future is expected to reach 400 billion yuan or more. ...
