Problems solved by technology

[0002] Flexible cables for power station units 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; The above cables have a high scrap rate in the production process, and most domestic cable factories do not have the production capacity of this section
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

Embodiment Construction

[0022] The following are preferred embodiments of the present invention, and the present invention can be implemented by any method according to the content described in the description.

[0023] Describe in detail below in conjunction with accompanying drawing:

[0024] See attached figure 1 , the capacity-increasing energy-saving flexible cable for power stations includes: conductor (1), conductor shielding layer (2), insulation layer (3), insulation shielding layer (4), copper tape armor layer (5), outer insulation layer (6) , flame retardant layer (7), sheath layer (8).

[0025] The conductor (1) is made of multiple strands of tinned copper wire; the conductor shielding layer (2) and the insulating shielding layer (4) are extruded from semi-conductive rubber; the material of the insulating layer (3) is ethylene-propylene rubber; copper tape armor The armor layer (5) adopts S-shaped double-button armor structure; the outer insulating layer (6) is made of multi-layered pol...

Abstract

The invention provides a capacity-increasing and energy-saving flexible cable used in a power station. A conductor screen layer, an insulative layer, an insulative screen layer, a copper strip armor layer, an outer insulative layer, a flame retardant layer and a protective sleeving layer are wrapped outside a conductor in sequence. The capacity-increasing and energy-saving flexible cable used in the power station has the advantages of being energy-saving, pulling resistant, flame resistant, weather resistant, good in bending radius and the like, thereby being especially suitable to be used as a main line cable of a power station unit.

Description

technical field [0001] The invention relates to a cable, in particular to a capacity-enhancing and energy-saving flexible cable for a power station. technical background [0002] Flexible cables for power station units 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; The above cables have a high scrap rate in the production process, and most domestic cable factories do not have the production capacity of this section. 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 cab...
