Abstract
The utility model discloses a special-shaped armoured cable. The cable includes a cable core, a steel band armoured layer, a reinforced steel wire and a protective cover. The steel band armoured layer is disposed outside the cable core, and the cross section of the steel band armoured layer is triangle shaped. The armoured cable employs an armour having a triangle-shaped cross section. The tensile strength of the cable is enhanced by utilizing the stability of the triangle. At the same time, the cross-sectional area is reduced, and the cost is reduced.
Description
Technical field
The utility model relates to cable technology field, relates in particular to a kind of special shape armored cable.
Background technology
Cable is the bridge between power supply unit and power consumption equipment, plays the effect of electric energy transmitting.Along with the development of national economy, cable is more and more wider in the range of application of China, although adopt the cable of steel-tape armouring to be embedded in underground more, but the electric power that is also widely used in subway, factory building and house is simultaneously carried, when the effect due to gravity aloft time of cable level frame, cable can produce certain bending, if accumulation for a long time may make copper cash occur part fracture.Meanwhile, the cross section of cable is larger, and material used is more, and cost is also higher.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide the cable of a kind of low cost, tension, has solved the problem of the not good and high cost of pull resistance that existing cable technical field exists.
The purpose of this utility model realizes by following technical scheme:
Special shape armored cable comprises: cable core, steel-tape armouring layer, reinforcement steel wire and protective sleeve, described steel-tape armouring layer is arranged on the outside of described cable core, and the cross section of steel-tape armouring layer is triangular in shape.
Compared with prior art, one or more embodiment of the present utility model can have the following advantages by tool:
Adopting cross section is leg-of-mutton armouring design, utilizes leg-of-mutton stability, can strengthen the tensile strength of cable; Reduce area of section simultaneously, reduced cost.
Other features and advantages of the utility model will be set forth in the following description, and, partly from specification, become apparent, or understand by implementing the utility model.The purpose of this utility model and other advantages can be realized and be obtained by specifically noted structure in specification, claims and accompanying drawing.
