Abstract
The invention discloses a distortion-tolerant fireproof power cable. The distortion-tolerant fireproof power cable comprises a cable core; the cable core is composed of a conductor, and an insulating layer, a mica tape wrapping layer and an inner extruded wrapping layer which are all covering the conductor, wherein a plurality of groups of elastic connecting pieces are formed on the periphery of the inner extruded wrapping layer in the extrusion process; the elastic connecting pieces are evenly distributed on the outer ring surface of the inner extruded wrapping layer and are as long as the inner extruded wrapping layer; meanwhile, the elastic surfaces, far away from the extruded wrapping layer, of each group of elastic connecting pieces are located on a same ring surface and the ring surface is defined as a top ring surface; grooves are formed in the elastic surfaces, far away from the extruded wrapping layer, of the elastic connecting pieces, and a plurality of groups of grooves are formed and distributed in the length direction of each elastic connecting piece; the top ring surface is covered with a wrapping layer which is formed by wrapping tapes wound in the grooves, and the thickness of the wrapping layer is less than the depth of the grooves; an outer extruded wrapping layer covers the wrapping layer. Due to the adopted elastic connecting pieces, the distortion tolerance of the cable can be improved; in addition, the cable is high in fire resistance.
Description
Technical field
The present invention relates to power transmission technology field, particularly relate to a kind of warp resistance fireproof power cable.
Background technology
Countries in the world have all turned one's attention to the clean energy resourcies such as nuclear energy, photovoltaic, wind energy, and the exploitation of renewable resource has become majority state energy strategy.Along with the bankruptcy of large quantities of photovoltaic enterprise, majority state is for the resistance of nuclear energy, and the spatter property of wind energy, recyclability, resource popularity make it get most of the attention, become on the largest scale in all new forms of energy, technology is the most ripe, the power generation mode that has business development prospect most.Also just urged the development of the supporting cable industry of wind power generation simultaneously.But due to wind field bad environments, and power cable swings and distortion with impeller, long-time impact by distortion also can cause cable core to break useful life of core, shortening cable.
Summary of the invention
Based on the technical problem that above-mentioned background technology exists, the present invention proposes a kind of warp resistance fireproof power cable, and this cable distortion resistance is strong, can prevent cable to break the problem of core because of distortion cable core.
The present invention proposes a kind of warp resistance fireproof power cable, comprise: cable core, cable core is by conductor and be coated on the insulating barrier of conductor periphery, Mica tape layer and the interior layer that extrudes from the inside to the outside successively and form, wherein, what inside extrude layer organizes Flexible Connector extruding in process to be formed with on its outer peripheral face more, Flexible Connector along in extrude layer outer ring surface to be uniformly distributed and the length of Flexible Connector is consistent with the interior length extruding layer, simultaneously, each group of Flexible Connector is away from the interior elastic surface extruding layer on same anchor ring, and to define this anchor ring be apical ring face; Flexible Connector is being provided with groove away from the interior elastic surface extruding layer, and groove is provided with many groups and length direction along Flexible Connector distributes; Face is coated with lapping layer to apical ring, and lapping layer is formed by wrapped twining package tape in each groove, and the thickness of lapping layer is less than the degree of depth of groove; Layer is extruded outside lapping layer periphery is coated with.
Preferably, Flexible Connector is organosilane crosslinked polyethylene.
Preferably, extruding layer outward is also organosilane crosslinked polyethylene.
Preferably, conductor is closed by multiply soft copper skein silk and forms.
Preferably, fire resistant infilling is filled with in the gap between lapping layer and cable core.
The present invention arranges the distortion resistance that can improve cable by Flexible Connector, and elasticity connects the resistance to tension also adding cable accordingly as connector, simultaneously, fire resistant infilling is filled with in gap between lapping layer and cable core, fire spreading speed can be effectively delayed in time running into fire, extend the uptime of cable core, improve the fire resistance of cable; In the present invention, the periphery inside extruding layer is formed organizes Flexible Connector more, Flexible Connector along in extrude layer outer ring surface to be uniformly distributed and the length of Flexible Connector is consistent with the interior length extruding layer; Such structural design can make Flexible Connector extrude a layer one-shot forming when extruding with interior, and production technology is comparatively simple; Flexible Connector is being provided with groove away from the interior elastic surface extruding layer, and groove is provided with many groups and length direction along Flexible Connector distributes, and lapping layer is formed by wrapped twining package tape in each groove, and the thickness of lapping layer is less than the degree of depth of groove; Such structural design can guarantee Flexible Connector extrude outside can be deep into time layer carries out extruding outer extrude in layer with extrude layer outward and became one, strengthen the stability of Flexible Connector.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of warp resistance fireproof power cable that the present invention proposes.
Embodiment
