Problems solved by technology

[0002] Domestic urban ring network transmission lines generally adopt a three-core structure, and the laying and installation are completed at one time. However, the heat dissipation of the cable is poor, and the thermal resistance between the cable cores is large. When the cable conducts electric energy, the conductor resistance becomes larger, and the power loss increases greatly.
If the conventional single-core structure is used, the heat dissipation is good, and the carrying capacity of the conductor is increased by 30% compared with the three-core structure of the same cross-section, but the workload of cable laying is heavy, which may easily cause unbalanced three-phase loads

Abstract

The invention provides a capacity-increasing, energy-saving and inflaming-retarding power cable. The portion outside a conductor of the capacity-increasing, energy-saving and inflaming-retarding power cable is sequentially wrapped by a conductor shielding layer, an insulation layer, an insulation shielding layer, a copper strip lapping layer, a galvanized steel strip armoring layer, an inflaming-retarding layer and a sheath layer. The capacity-increasing energy-saving and inflaming-retarding power cable has the advantages of being energy-saving, tensile, fire-proof, weather-resistant, good in bending radius and the like, and especially suitable for being used as main line cables in projects like power stations, airports, train stations, subways, buildings and tunnels.

Description

technical field [0001] The invention relates to a cable, in particular to a capacity-enhancing, energy-saving, flame-retardant power cable. technical background [0002] Domestic urban ring network transmission lines generally adopt a three-core structure, and the laying and installation is completed at one time. However, the heat dissipation of the cable is poor, and the thermal resistance between the cable cores is large. When the cable conducts electric energy, the conductor resistance becomes larger, and the power loss increases greatly. If the conventional single-core structure is used, it can dissipate heat well, and its conductor carrying capacity is increased by 30% compared with the three-core structure with the same cross section. Combining the advantages and disadvantages of three-core cables and single-core cables, a cable with easy installation and excellent heat dissipation can not only meet the saving of copper and aluminum metal consumption, but also reduce v...
