The development of the square power cable of the low inductance of Environmental Protection in China type direct current is started late, the technical merit of each producer is uneven, add more and more higher to the requirement of base station power wiring system in recent years, cause many producers due to technical force limited, can not design, produce the square power cable product of the low inductance of environment-friendly type direct current meeting technical requirement.And there is following problem in production technology: 1, processing capacity is large, and production cost is high.2, be unfavorable for laying, managing, risk factor is large.3, be unfavorable for the assembling of finished product, the production cycle is long.4, volume is comparatively large, waste material.
Utility model content
The purpose of this utility model technical problem to be solved be just to provide a kind of not only have good corrosion-resistant, oil resistant, heat-resisting, ageing-resistant, Halogen, low cigarette, low inductance, low-loss, low noise properties, also have excellent bending, the low inductance power cable of environment-friendly type direct current that soft tensile property can be widely used in the system of the power transmission that communication base station requires.
The low inductance power cable of a kind of environment-friendly type direct current described in the utility model, this whole cable is square structure, and area of section is 4-16mm
2, comprise cable core, the outer overlapping wrapped double-deck PBT polyester band inner covering of cable core, inner covering weaves tinned copper wire screen, high strength fibre silk reinforced layer outward successively, then outside reinforced layer, extrude 125 degree of cross-linking radiation polyolefin outer jackets; Described cable core is made up of the rectangle insulated wire cores of 2 parallel placements; Described rectangle insulated wire cores is made up of flat rectangle conductor and the 125 degree of irradiation crosslinked polyolefin insulating layers be extruded in outside flat rectangle conductor.
Further improvement, the parallel placement of tinned copper wire that described flat rectangle structure conductor is closed by the 6th class bundle is formed.
The beneficial effects of the utility model are:
1, the utility model conductor is flat, rectangular structure, is that many 6th class tin-coated copper tow conjunctions form, enhances the tension of cable, bending, soft, decay resistance; Employing strap is arranged in parallel, and cable can be made to possess the performance of low inductance, and surface area is large, strengthens radiating efficiency, then increases current load amount.
2, the utility model insulating barrier adopts and sheath employing cross-linking radiation polyolefine material, after electron accelerator irradiation, its heat resistance strengthens, guarantee that cable can for a long time at 125 DEG C of operate at ambient temperature, and can bearing great current, strengthen system cloud gray model fail safe, extend the useful life of cable.
3, the utility model screen adopts tinned copper wire braiding, and this braid not only can replace ground wire as concentric conductor, bears the effect of unsymmetrical current, also greatly increases the softness of cable.
4, the utility model reinforced layer adopts the braiding of high strength fibre silk, and as heavy seal coat, it has that quality is light, tensile strength is large, quality is soft to this braid, further enhancing the softness of cable.
5, this product structure is simple, and stable performance is easy for installation, good looking appearance; And product with short production cycle, output is high, production cost is low.Personnel reduce 20% compared with traditional processing technology, and the electricity charge reduce 30%, save protective cover material, packing material 50%, conserve space 25%.Volume is little, and saving space and material are beneficial to mounting and installation, reduce the production cost of manufacturer to greatest extent, improve the cost performance of product, really reach efficient, energy-conservation object.
